Ive got an 05 mustang 4.0 (V6) with axle-back flowmaster 40 series and it sounds good....but i want more sound. Any suggestions? Would running an x or h pipe into dual 40 series make a difference? Ive also heard that changing my exhaust pipe to 3.5 inch or 4 inch will make it growl...

yes h or x would help, but 3.5 or 4 inch tubing wont help sound, you will just loose back pressure.

hmmm...so running it from the single exhaust to the dual exhaust with an x or h pipe would help significantly with the sound. What about taking the cats off?

[IndyColts08]

okay...what about 3 inch tubing? THe x or h pipe to duals instead of singles will help sound sigificantly? WHat about taking off the cats?

[tjames]

yes true duals with H pipe will make a difference. now that i look again you have a s197 and idk alot about the s197, but i do know that duals with h or x will help but it will still be really quiet, look on youtube for some clips

2.5 inch pipes with an h pipe and flow 40s should sound mean and loud. plus give you a little more power, cam and headers will also add some nice growl to your exhaust.

S197 doesn't get loud -

You could try removing cats and going h/x pipe + long tubes.

ya like i said on youtube there are clips of the s197s but none of them are LOUD and IMO none really sound that great

yeha, it seems that the 4.0 just does not sound as good as the 3.8 in general. Not to say it cant sound good but i really have not heard any that sound real nice.

take off your mufflers and it will be plenty loud.
