Thats the other thing...hpipes pretty much sound the same no matter what brand it is. X-pipes on the other hand sound different depending on the brand/design of the crossover. I havent heard many good comments on the sound of the bbk piece but i have no first hand experience.
woah there buddy. You can ask all those questions in one post ya know. Yes, headers will make it sound better. Your best bet would be longtubes cause they sound great.
This is the best way to tell you,if you go up to nmcgrawj he's on this page and click to listen to the sound clips of bassani and click on
[Bassani Bassani O/R X Shorty - - Nic 95Cobra] and thats the sound Im looking for.
I love the sound of my BBK, but as for fitment it is crappy. I have BBK headers with the BBK X and i can never get it to fit correctly. I have a leak at the header flanges. I also had an exhaust shop install it.
i know a guy with stock headers, bbk X pipe and flows, and i personally think it sounds badass, its a tad quiet at idle, he is fixing to slap on some bbk headers, that should help out. but at WOT it screams and sounds nice.
bbk e/l headers, bbk catted x pipe and flowmasters.... sounds damn good to me. had a few problems with exhaust leaks but not anymore and the x pipe fit like a glove.
x-pipe at wot has more of a scream.. h-pipes go great with flows.. deep throaty sound.. all depends on what you like.,. all my cars have dr. gas x-pipes
