Need a better exhaust sound

[phalcrow]

I currently have BBK shorties, off roah h-pipe and flowmaster 40 series. I wanted to know which component of the exhaust gives it the deep, throaty growl I hear from other mustangs that mine seems to lack. I had XE-262AH and am replacing them with XE-270AH as soon as I get my motor fixed. I was wondering if long tubes change the sound much because if it does, I'll go ahead an do that while the motor's out because we all know how much of a pain in the a** changing headers on a 4.6 are. Since I have to get a new mid-pipe, I'll probobly get cats on this one because CA is pretty strict about that stuff.

Swap the h-pipe for a prochamber. If this doesn't do it for you, get some MAC mufflers.

If you are in ca then don't do longtubes...you won't pass smog and will have to put your stockers, or shorties back on.

Yep, California. But I'm running XE-270AH and a tune and stuff. I don't think my stock exhaust can help me anymore. I'd practically have to swap in my old stock motor to pass and if I do that I would swap the exhaust back as well.... or just pay someone off and not get greasy.

I have a 2011 Mustang v6 that I just purchased, and the person i bought it from, made it into a Cobra tribute....but I wanted to just drive it this summer, than maybe drop a coyote into it next year, but i wouldnt mind it sounding better than stock....any suggestions?? Are bolt on kits from the axle back worth using on a stock exhaust?? Thanks!!

Kdub96,
I put Pypes, Pype Bomb exhaust on my 97 Cobra. I think it had a Flowmaster catback system on it. I love the sound of this system. To me, it's what a muscle car should sound like. It has a deep, throaty sound to it. It's pretty loud, but not annoying loud. The mufflers, if you want to call them that, are just open, no restrictions, with resonators for the tips.
