Title: turbocoupe side exhaust ?
Post by: quicksilver on July 21, 2009, 01:50:29 PM
does anybody know what a turbo coupe would sound like running a 3" magnaflow exhaust(cat and ler) that comes out right before the the driverside rear tire sounds like? just a single exhaust.

ive got duals on my 79 XR7,2.5 pipe with custom glasspacks ,i have them coming out right before the back tires on both sides and i love them,,if ur gonna spend the money id go with duals,heres a pic of one side of mine

Apples and oranges...a single 3" is just about perfect for a 2.3T.
You'll be hard-pressed to package a cat and ler and get out before the rear wheel. At least not w/o the tubing making a hard turn to get there.
How will it sound? Like a tractor, just like all 2.3T's. It will just be louder to everyone on the driver side of the car.

You could use a ler like my friend is using on his '67 Stang.They are from Flowtech,and the exhaust "in" and "out" are at the front of the ler,like the old T/A Challengers and AAR Cudas.

At that point, what's the purpose of a side exhaust (which is usually meant for the shortest, smoothest flow)?
You'll probabaly have to use a bullet-type ler if you want to package it with a cat and make the turn. And it won't be quiet, and it will drone under your seat the entire time...

I say,in my own opinion,keep the exhaust out the back.I always thought that,for most cars,side exhaust looks like the cheap way out,incomplete.......for most cars,ours included.

Post by: 1979 Cougar XR7 on July 21, 2009, 04:05:47 PM
it wasnt the cheap way out for me,,,u have to have the right kind of car for side exhaust tho, on that body style i would cut my tips off and put turndowns on where the exhaust couldnt be seen

ok thanks for your help. i didnt put into consideration how loud it would be dumping out right beside me. should i go 3 inch to the ler, then dual 2.5 running out the back?
Title: turbocoupe side exhaust ?
Post by: bhazard on July 21, 2009, 06:46:00 PM
Single 3inch gives the best flow, duals give the best look, they both sound great. Doesnt really sound like a tractor if you have lers.
If you dont have emissions ditch the cat.

how do you figure that 3" flows better than a 3" dual 2.5" setup? if you do some simple math you will see that dual 2.5" equals 5" wich would flow much better than a full 3" now I could be wrong but I think the duals are the better choice and is what is on my TC

You're not making enough power to take full advantage of either.
For most people it comes down to personal choice for looks, ease of install, or cost. A single 3" or dual 2.5" tails is not going to affect power output for 99% of 2.3T folks.

"Yawn" = the debate between the 4 cyl. engines and the V-8 engines.It's a pointless conversation.They both have benefits and disadvantages.6 of one,half a dozen of the other.I love my V-8,but,I also have a deep respect for the turbo 4's around here.The Turbo Coupes (and XR-7's) have proven to be great all around performance cars,as do the modded V-8's.A stock 5.0 car,in my own opinion,can't hold a candle to the Turbo Coupes for example.They can REALLY surprise a person who doesn't know any better.The debate will always linger,but there's no point in getting into it here.We all are here for the cars,whether it's a 4,6,or 8.We (Fox Cat and Bird owners) aren't nearly as large a group as the Stang guys,so we have learned to really respect these cars for what they are,and what they can be with very little work....even more with a lot of work and the right parts.

i agree there are some stout 4 cyl's out there especally on this site,,,but i dont have a stock 302,, i havent got anything against a 4cyl ,,but everyone has to admit to acheive a nice rumble and great sound from ur car uve gotta have a v8

X2 i love the rumble,... and when you hit the gas in neutral, the whole car shakes a bit,..... or a lot with a lot of horse...... oh yeah.......id love to ride in a turbo coupe tho......
Title: turbocoupe side exhaust ?
Post by: vinnietbird on July 21, 2009, 11:34:24 PM
No doubt about it,nothing is like a nice V-8 rumble,BUT,how many V-8's with 130 horsepower sound great,but can't hardly pull the car's weight.Sound is good,but that doesn't make the car move.Most posers rely on noise and stick on stuff for the look and sound,and hope that no-one calls their bluff.I've always thought a car should back up what it's selling (so to speak).
Now,let's drop this subject and move on to better topics.

To get theoretical flow capability one would take the area of the casing(s) that the fluid will flow through.
Keep in mind that most tubing is measured in O.D specs and that the real way to measure the area would be to find the inner diameter. To keep it easy, we'll use O.D as some tubing has different gauge thickness.....
One 2.5" circle has an area of 4.91 square inches
That means 2 have an area of 9.82 square inches. One 3" circle would have an area of 7.06 square inches.
More cross sectional area means more flow potential, but sometimes less is better. To put it simply you want the least restriction while in turn keeping the exhaust gas velocity as high as possible. Too big of a diameter pipe(s) will slow exhaust velocity and have a negative effect on scavenging resulting in less power AND efficiency. Remember that there are many other factors concerning flow as well exhaust port shape/size, header diameter, collector size/shape/length, exhaust piping diameter/length, the ler type/size/.......the list goes on.
Anyway.....................take it from someone who had side exhaust and switched to dumps. The side exhaust will annoy you after a while. Ground clearance will become an issue as well. I went with dumps simply because I didn't want tails -- I wanted a clean look out back.
An interesting exit for a 3" would be an oval tip dead smack out the exact middle out back though. It would certainly catch a few eyes.

You also have to figure that a Y pipe will cause a restriction. And not to mention another tailpipe, youll have twice as many bends back there to restrict.
The simpler way will flow better. One big pipe, no splits, less bends. Saying dual 2.5 will flow better than single 3" is like say dual 2" will flow better cause 2+2=4 and 4>3. We all know just looking at a 2" pipe thats not the case.

ok, i think this is what i can come up with, 3"turbo back, highflow cat, one flowmaster super 40, then split into 2.5 duals with 3" wide 12" long stainless tips cut at an angle. do you think that would flow pretty well considering i have a racing header and T5 turbo?
Title: turbocoupe side exhaust ?
Post by: quicksilver on July 23, 2009, 08:36:05 PM
oh thanks for your help and input, i appreciate it. im also thinking about 3" all the way out too.

dont buy flowmaster(restrictive overpriced junk) I run twin magnaflows on my turbocoupe to dual 2 1/2" pipes and my car makes 400hp easy and it has no problems and is quiet. Sounds like a stock 5.0 instead of a cammed out 4 cylinder. I went for sleeper status on my car, rofl.
BTW: what is a T5 turbo??
Title: turbocoupe side exhaust ?
Post by: quicksilver on July 27, 2009, 03:15:59 AM
so do magnaflows flow better then flowmaster super 40's? i also want something that sounds good. the T5 turbo is off of 5 cylinder volvos. yeah, im have problems spooling it.... thats another reason im looking for a high flow exhaust
