wats up guys, im driving a 2001 Mustang GT and im thinking of ordering a Flowmaster 40 american thunder exhaust. ive been told flowmaster sounds nice at high and low RPM ranges but just wanna make sure if this was wat i want. im hoping to be getting a much deeper sound than the stock exhaust i have now and noticeable performance change. anyone with ideas and opinions would be great.

 

you wont see a noticeable performance gain with a catback. if you do full exhaust (headers, midpipe, catback) you will definitely feel it...but just a catback will net you myabe 3 hp tops or so...nothing noticeable from a butt dyno. but it will definitely be louder and deeper than stock. supposedly flowmasters have a drone somewhere around 2000 rpms ive heard (dont know...ive just heard). If you want deep...Bassani...very deep low rumble that sounds great with no drone. get an o/r H pipe with a Bassani catback...and youll sound INCREDIBLE.

 

you won't notice any gains out of a catback (NA) just the sound.

 

yeah, you can't hear yourself think

 

dam that really brings my hopes down on just getting a simple exhaust hAHA, so wat should i be getting in order to get a nice performance boost and same time nice deep sound? or am i just better off getting an x pipe or h pipe

im looking at this now, its catted so its legal
