new exhaust=how much hp?

[stangnut]

average horsepower gain from replacing exhaust? long tubes,catted x or h-pipe and exhaust. any guesstimates guys?

probably 15-20 at peak. But torque production will be up alot throughout the rpm range.

Magnaflow catback alone is an average of 10 rwhp.

 

[My94GT]

just changing cat bvack i gained maybe 2 or 3 rwhp

Magnaflow catback alone is an average of 10 rwhp.

Sounds a little high

 

[ogc]

I gained 22 rwhp with LT's O/R X and a catback.

255 - 277 rwhp a chip brought it up to 292.

 

[LILBLKSNAKE]

My car dyno'd at 272.9 with just a CAI and Magnaflow catted-mid and Magnaflow cat-back.
Longtubes and another tune might crank it up 10+rwhp???

I don't have an intake.

But yah car was running a little rich without the tune. So we messed around with it for a bit and got another 15rwhp with it
