Just Recently Put In A 2 And A Half Pipe

ALL OF A SUDDEN IM LOSING THE BACK END TORQUE...ANY QUICK MODIFICATION SO THAT I COULD GAIN THIS TORQUE BACK BESIDES REVERTING BACK TO A 2" PIPE...ENGINE IS STILL THE STOCK SOHC FROM THE 91 SI WHICH IS THE D16AZ I BELIEVE

gotta revert back to 2" piping if you wanna get the back pressure back, not to mention that your car probably sounds like shit with the larger piping.

IT SOUNDS PRETTY LOUD...LOL
ITS LIKE I WENT FROM A PIPE TO A BONG....

what do you mean by back-end?? My SOHC d15b2 got stronger at anything above 5K with my 2.25" pipe and turbo muffler. :confused:

And it only has 92 HP to start with. I love my sleeper exhaust. Just need that damn ZC in there ;)

any backpressure at all = bad.

no back pressure at all = no torque

no back pressure = torque at higher rpm.

yeah...well who needs torque at higher end..you're already in motion ;) ..honda's have like no torque to begin with..why make the problem worse

HMMMMM...

all the ideas about backpressure really depend on each individual situation.

soo then whats a good size 2inch?

2 1/4

Ive got 2 1/4 inch pipe...with no problems....

2 1/4" pipe seems ideal for a mildy modified engine. If you are getting crush bent piping, i would suggest 2 1/4" on the straight, and where it starts bending, go to 2.5" as the crush bends tend to restrict the pipe.

thats what i was thinking

I WONDER...SHOULD I JUST LEAVE IT OPEN HEADERS?
LOL....IT HAS NO BACK PRESSURE WHATSOEVER AND ITS LOUD BUT DAMN....
