why is it soo cheap? is the piping 2.5 inches? does it include the catayltic converter, so i can throw out that rusted piece of shit on my car? will it bolt right up to my star downpipe? tia.

no its a cat-back, sorry

No cat converter but what do you expect for $160. I have one with a different muffler welded on and I like it a lot.

so dave what did you do about your downpipe? are you still using the stock/hahn hybrid? if so, i think that you are really not getting ANY power from the pacesetter, or only a slight bit. also, are you using a gutted cat, a testpipe, a hi-flow, or stock?
im curious because thi sis my next power adding mod. either way, what gains did you feel with each part, and which ones do you have? (im especially curious what i am gonna do about a downpipe).

i need to know what high flow cats are good. i saw the one on machv.com, they got a Buschur Racing high flow cat, for 150, it comes in 2.5 and 3 inch diameter. which is better? im getting the pacestter 2.5 inch exhaust, so which diameter would be more efficient. the star downpipe is 2.75 inches. so would that all bolt up no prob or what?

I have the 2.5" hahn down pipe and I have the stock flex section welded to it. I think I am going to have that small section that is still stock cut out and get a 2.5" section welded in its place. And it made a huge difference from the stock piping I had.

The Pacesetter Catback WILL make a big difference by itself bolted to the stock DP and cat. Anyone with a turbocharged system will feel a sizeable improvement in HP with a cat all by itself, and then additional improvement per each increase in size at the cat and then the DP. Just make sure you upgrade from the back to the front and not vice-versa (i.e. Catback, Cat, DP).

The HRC DP is only 2.25". It's bolted up to the stock DP which is 1.75" to 2" depending on which part of the press bend you're referring to.
