Wzup peeps, I just wanted to give my opinion on the catback and hope it can help the newbies with questions (hope it's not in the wrong forum). Anyway, my concerns with a diff exhaust were pricing and sound. I didn't want anything too loud (that's what my motorcyle is for) yet wanted performance gains cheap. Well let me tell you that for the money approx. $180 shipped from Nopionline this setup is good. Defenitely feel the diff. at top end, you can feel the higher than stock flow, allowing the car to reach higher speeds quicker and the engine to reach high revs quicker. I don't feel a noticeable diff. at low end. The sound is a deeper tone, I don't get the "coffee can" effect I've read many post about while regular daily driving. I do get it for just a bit when pushing the car (racing) but not enough to bother me. I LOVE my new setup. The mid pipe (connecting to catalytic converter) and pipe connecting to the muffler are identical to stock, the muffler is a little smaller than stock and the tip is 2.5", all pipes and muffler are painted black, only tip is chrome. My car is black and I like the look, I took off the gay yellow sticker and spray painted the yellow inside of the tip black also and to me it looks good. After working and installing this on my own which by the way is easy to do I realized that just getting a higher-flow muffler would've been just as good since the mid pipe and pipe connecting to muffler are identical to stock, these pipe have to bend around the gas tank in order to fit under car unless you plan on doing custom work. Hope this helps those interested in the Pacesetter catback and aftermarket mufflers.
