I have intake and i just installed a cattman y-pipe, is it worth it?

 

Yea, all you need now is a hi flow cat and a cat-back exhaust and yoo are set with the exhaust mods on your max. You can get a good hi flow cat from www.randomtechnology.com

 

the Y-pipe's definitely worth it. as far as exhaust goes, if you really wanna spend the money, u can get that hi-flowing cat the other guy mentioned. also for catback, if you want a high-pitched sound, get the stillen, for a lower, droning sound, get greddy. if you want some small performance gains, but with as little sound as possible, get a stillen B-pipe and keep the stock muffler, or even better, install an Infinity I-30 muffler :-) personally, i don't see much at all of a performance difference between greddy and stillen, i went greddy cuz i got a decent deal on it. but if it came down to it, i'd go stillen becuz their products are top notch. good luck, and enjoy the Y!!

 

Good!

Y pipe with intake, Better!

 

the catback exhaust in itself doesn't yield HUGe gains but when you work it in conjunction with a less restrictive intake tract and a Y pipe, you'll get the most out of it.

The setup you have now is fine, but you'll take full advantage of the higher flowing Y pipe section with a less restrictive exhaust path after the Y pipe. You can probably find an exhaust shop to make the B pipe section less expensive than a Stillen or Courtesy pipe, but I recommend you spend an extra few dollars on the muffler section. The less expensive universal mufflers generally sound terrible. The Stillen muffler section or an A'PEXi universal muffler would be a good match.
