Title: h-pipe
Post by: tbird96h on February 01, 2005, 10:32:07 AM
will a bbk h-pipe with cats bolt up to some mustang headers i'm going to be putting on my 1988 5.0 tbird?  how about the catco h-pipe with cats?

i'd rather use the bbk because it's 2.5" rather than the catco 2.25" but if the bbk won't bolt up to easy i'll prolly save the trouble and get the summit h-pipe and buy some high flow cats, thanks guys  :)

Yes it will....I run BBK shorty's and a MAC 2.5" H with cats on mine...fits no problem.

Nice pic Hawk. Did you just clamp those at the seams?  Or did you weld them also? I had been wondering if you could get away with just clamping an exhaust together or not.

yeah man it should fit fine.... all except if you dont have the double hump crossmember im gonna be running everything stock until i get to the catback, mustang shorties LSC h-pipe and a flowmaster 2.5 american thunder catback system with 3.5 inch tips

btw hawk, that car is freakin' sweet! you must win alot of races with that baby ;) and have drooling doofuses like me staring at it  :evilgrin:

BTW tbird96h- is your car stock? if so... you might loose all your torque if you run 2.5 all the way out  someone correct me if im wrong....

it's stock, maybe i'll throw some lers on there, that should keep enough back pressure right? i ran straight piping on my last bird a 96 4.6L n/a, and i think i did notice a loss in low end torque, if i were to put glasspack lers on it, would that keep enough torque and give it a nice low rumble? if not what ler would give it a really loud and agressive sound? i don't want the transam sounding exhaust, or mustang exhaust, i want some nice loud agressiveness to it, any input is appreciated, thanks

I personally like the Dyno Max Ultraflo's. Decent sound, decent backpressure. Good product.

That is what I got. If they make a 3.8 sound decent, I can only imagine what they could do for a 5.0.

Hey tbird96h,what part of Texas are you in?I'm in Ardmore ,Ok.South central part of the state right above Gainesville.
Oh,I now have the Mark VII headers and H-pipe with the cats hollowed out.I cut the intermediate pipes (so I could unbolt and swap exhaust parts easier)from the Mark VII and spliced them to my lers and tailpipes.Since I got the Mark VII for parts,my total cost was $8 for 4 clamps and 2 connecting pipes (6 inches long).I can feel a difference in the car.I'd like some Flowmasters now,but,my attention is on getting the H.O. 5.0 in it.

 Thanks bro. As for races.....never really had one yet. I played with a Pantera GTS once and a modified Camaro SS (pulled on both) while getting onto highways but other than that nothing....most would be's don't bother me at stoplights when they hear it idle...the lumpy idle and whine from the blower seem to scare people away which is fine with me...I've never been into the street racing thing.

No clue...car hasn't been down a strip since '91 and probably never will be again.....I'm not into the drag racing thing at all and with the suspension setup I run it won't hook for shiznit on a track.
