Hey kind of new here,
I have a beautiful bone-stock 88 tc that I'm trying to put 3" exhaust on. (No cat, Cherrybomb ler, header down). But the shop I took it too said 3" wouldn't fit, 2.5" probably wouldn't either. my car is kind of low to the ground, but i've seen punks in hondas where the pipe is a hairs breadth from the asphalt and they do fine. (some of those "punks" are my friends lol). So does anyone here have some input?
Lots of guys here run a 3 inch single from Stinger (http://"http://www.stinger-performance.com/headerparts.html")
Yea I'm going to get a stinger my self
I custom build those exhausts all the time. 3" in to a CAT then back with 2 1/2 all the way past the axle. Don't use a ler . Use only a cat. If you use a ler you are going to loose HP & Torque. I have been building Coupes since they came out. Forget a ler it will cost you ponies. Other than if you want it super quiet that is. Installing a system that is to large will cost you ponies,
:burnout:
I had the stinger 3" to dual 2.5" on my silver TC no issues. but mine was at stock ride height... I will snap a pic of the exhaust.
here is what I have, it is the stinger 3" to dual 2.5" and flowmaster 40's

That sounds good
Makes me want to keep my flowmasters
My bird is lowered with a 3" all the way to the rear with the Magnaflow straight-through ler and no cat - all from Stinger - all installed by me, in my garage. I have no fitment issues or rubbing. Kinda scared of speed bumps, but it's been on a year now and no issues. Here's a short video I took (with the help of a co-worker) to show another guy how the system sounds:

It won't let me view it
Do you have any you tube clips? That is the set up I'm leaning towards
Dangit... I'm really starting to dislike Photobucket. Ever since they updated the site, nothing works right. I'll upload it to YouTube later tonight.
That thing sounds absolutely beautiful. Your setup was basically what I was going to put on mine. My honda friends taught me all about avoiding speed bumps lol, I think ill do it. :D
Cool it could also be that I'm on my phone a lot of stuff dose not work right

And this is how the car sits:

Must be his phone cause it loaded up fine for me, but maaaan that thing is pretty low, whats the drop on those springs?
I went old school (read FREE)... cut roughly a coil and a quarter off the fronts, about an eighth of a coil off the rears, and lost the isolators all the way around. I can't remember how much it dropped it. This was a couple of years ago. But what you see above was the result. :)
Lol nice, well it looks good. Hope you got shocks to compensate XD
OH shiznit HERE WE GO AGAIN
The Y and the duals are a killer for flow. That system is very restrictive. A single exhaust flows much better then the dual setup. Other than looks. And a passion for 2 pipes out the tail a single system out performs the dual system hands down. Ok now you can pound me.
Hla issue!!!
Lol I realize the whole exhaust topic has probably been done many times over so i'm sorry ;] . But yeah I totally agree, Dual exhaust is awesome for the v6's and the v8's. But I got a TC, I just want one fat pipe all the way to the end just like Bleavitt23.
Make sure you wrap the down-pipe. I'd run a highflow cat and a straight thru ler, single tail.
I have 3" on all my turbocoupes. two have 3" all the way back and the third is dual 2 1/2" out the back. I havent found a whole lot of stingers stuff that fits to my liking, but still fits fine. I don't have any cats and run nothing but Magnaflow lers. Flowmasters are proven power robbers! I actually have 2 different magnaflows on my autox car, and its still almost too loud to pass the 100db at 75' or so thats required at autox
Thanks for all the input guys! I always wrap my headers/exhaust, the extra bit of power IS noticable. But how about straight-through glasspacks? (I have a 3" cherrybomb just sitting around I was planning on throwing on there). Should I use it?
A cherry bomb is not a glasspack. Its a resonator, and its loud as shiznit. If you run glasspacks, make sure you pay attention to which way you install them. One way will sound good, the other will sound loud as shiznit. The turbo will quiet the exhaust somewhat, a glasspack will quiet the exhaust more than a magnaflow, but you may take a hit on flow.
You can try a dynomax ultraflow vxt, its straight through but it has a spring loaded redirect door in it.
FOE just for the record a ler even a HI flow one robs HP. Yes running a CAT is the way too increase HP. I guess you have been to the Ford TECH schools. They teach you that in those courses. Have you been to them. Cats makes more HP. Think about this why do the V engines connect each bank together at the engine pipe??? You know an X pipe !!! Same theory. But an INLINE does not like to much exhaust and no engine likes a ler . It robs HP. The CAT increases flow and by a good amount!! LOW CELL COUNT ONES, Modern ones i should say. Some cars are CAT ONLY FROM THE FACTORY. The Engineers know this now. Been messing with exhaust for years. lers rob HP. Other than noise or to pass an inspection i do not run lers.
OK why do people WRAP PIPES is what you sshould be concentrating on. Correct now WHY!!!! For the same reason you should not run a ler. But for the same reason to run a CAT. Think about this and i will post back. I have dun extensive Dyno testing on the 2,3 over the years and i know what works. The DYNO DOES NOT LIE.
Very restrictive as well. Think about it FOE.
Glass packs and cherry bombs have an arrow on them. If not they should be installed with the cones facing the engine to make them Quieter. Away from the engine to make them louder. I do not use them they SUCK and rob Ponies from the PONY.
We're talking about street cars, Tom. I wouldn't give up a ler for anything, I just couldn't live with all the noise. I think that even though a straight through ler cuts flow, it doesn't cut much. And I'd be willing to bet you can't tell when driving it. From my reasoning abilities, a straight through with a flow tube equal to the size of the inlet and outlet should only reduce flow in that it allows the gas to expand and slow down in the ler (which is why it works). I can't see this being detectable on the street. The dyno, yes. The track, maybe. On the street, no chance. Livability has to be considered. THAT, and it's required by law in every place I've ever heard of. Maybe you're so hardcore that you can deal with no lers, but I'll bet that's not the case with everyone.
I noticed a difference when I went from a true dual with a 2 inlet/2 outlet flowmaster, to a 2 into 1 pipe, with a single in/out flow and a 2.5" tailpipe. Big difference, both in power and sound.
But I had to do it that way to get it to pass inspection. Come spring, it'll go back to a dual in/out and have custom pipes ran to the rear.
Got it FOE. Not the answer though. The lers have the greater losses not from restriction issues. By the way HP IS HP and the difference on the street is most definitely noticeable. By the way more and more manufacturers are eliminating lers and just use the cat as the ler. As far as sound if you read my post i clearly said if sound was an issue use lers. But the 2.3 with a full exhaust single in nature cat only is not loud by any means. Ok enough said. But that is why people have cars that outperform others. They realize exhaust tuning can net several HP gains. And substancial gains. Thanks for listening!
The worst lers bar none are as follows. The Thrush Turbo and Flow Master lers. This is a fact and we proved it. Just saying.
Anyone have a clip of just a cat
My car is so quiet it sounds like its powers by lithium ion battery's lol
lmao that sucks... Mines just factory stock, it lollops like a v8 at idle but once it revs it doesn't make much noise. Hell the whizz of the turbo and the BOV is louder lol =[. But yeah we're talking street cars, if I could get away with a straight pipe I would because I love manly loud engines, but gotta keep it legal. No cat, but yes ler. Technically not legal, but my state doesn't have smog checks :evilgrin:
I would never recommend a chambered ler to anyone. Straight through are best, but not all are equal. Turbos are only for the guy who wants a better quiet ler. Most turbo lers are garbage, so if thats your thing, do your homework. Mine is a daily driver so I'm running Dynomax Superturbos, just because my upstream is currently small (Mark VII stock h-pipe and stock HO headers) and I really hate drone. I'm gathering parts to make my headers and h-pipe bigger (down stream will come later) I'm going to send the headers to be ceramic coated and because, for budget reasons I'm going without cats, I'm thinking about wrapping the h-pipe to the balance tube. Tom recommend cats so ardently because the reaction creates heat downstream and acts as a scavenging aid and helps to keep velocity up. I'll be wrapping to try to get some of that effect and to keep the heat away from my trans.
Yeah that's what I was thinking, chambered lers are garbage, and turbo lers are next to garbage. I work under cars for a living and you should see some of the trash they put on cars these days (newer volkswagen lers look like a freaking second gas tank).
I just got the car not long ago it has stock down pipe cat with dual flowmasters
I hate it!
I've Ben looking for the cheapest way to get the sound and power
I would love a strate 3" with a strate through ler but that would have to wait a while
Tom recommend cats so ardently because the reaction creates heat downstream and acts as a scavenging aid and helps to keep velocity up.
OK NOW YOU GET THE IDEA!!!
Running a to big of an exhaust hurts this and that is why pipe size is critical. The CAT makes the car emission legal and keeps the gases flowing. This is better than most people think. Actually a proper running car with a low cell count cat can net good HP gains. Thanks
Thanks man, you really know your stuff! Yeah I did some research and to me it looked like anything bigger than 3" on the 2.3 turbo was too much pipe. Hows a car sound with no ler and cat only though?
That's what I want to hear
It would be ez and cheap to keep the cat and have A ler shop just run a pipe off the cat
Easy Way To Estimate: Your intake system needs to flow 1.5 CFM per engine horsepower, and your exhaust system needs to flow 2.2 CFM per engine horsepower.
Good Way To Estimate: Take engine RPM x engine displacement, then divide by two. This is the intake volume. Use this same volume of air for the exhaust system, but then correct for thermal expansion (you need to know exhaust temps to figure things out).
