exhaust question

[rockitman]

i have 40 series flowmasters with stock h pipe, i i go with o/r x pipe will it sound more agressive (louder,rasper) will i gain any performance? thanks Don

i prefer the sound of an x over the h. i think it sounds more racy. the x will be a better performance choice, an x configuration will scavenge and balance exhaust pulses better throughout the entire rpm range

it has been said the x is more raspy and the h is more like the sound of a big block.....not make this up I promise....MM&FF....

x-pipes sounds freaken awesome

Where you gain performance is in the size of the pipeyour stock pipe is 2 1/4" and most aftermarket pipes are 2 1/2" . I have had both the X and currently back with the H pipe i like them both.

I have the flows with an x-pipe. I think headers have to be done with aftermarket parts!
I had flows on my stock setup and then got bbk headers with an slp hi-flow x-pipe and it made a huge huge difference. The stock headers are absolute garbage!

It will give you about 15rwhp. Sometimes less, sometimes more. It will depend on how bad it throws off your fuel trims in your tune. A good tune with the off road pipe will give you the best performance.

The general rule of thumb as far as sound is:

X-pipe with straight thru mufflers

H-Pipe with chambered mufflers.
