Its the same setup as the tsudo. I dont know the quality comparison but if your on a tight budget and need to save some, there you go.

And you'll have to modify some. I had to cut my subframe to make it fit. Expect the gaskets to be a pain but you'll feel a noticeable difference once installed.

Alright, since a lot of you 2.2 guys are already chimed in, and this is on topic, I'm reviving it. Some of you have gotten things done since this, what? and how did it work? Clutch is going to have be done soon so I'm biting the bullet and doing the headers at the same time, with that, comes new exhaust.
Headers- http://www.ebay.com/itm/M2-Stainless...1663d7&vxp=mtr
resonator- http://www.ebay.com/itm/Vibrant-Perf...a7c7e8&vxp=mtr
Muffler- I'm still going catless despite the filth that now covers my tips. The sensor is tuned out, I'm on a budget, and the ultra quite resonator should make up. This is going to go right behind the resonator on the strait run mid-center of the car, for ease of getting over (or under) the rear trailing arm before y-ing off, and a few pounds placed a little better on the car. http://www.summitracing.com/parts/sum-630812
All that being said, everything will be fresh fabed between the header outlet, and however far he has to go splicing into the runs off to the tips. I really want to get some nice tips with all this but I can't swing it right now, once all that is done and they hung up against the bumper they'll be sufficient. Besides the fact I cleaned the car today and the crap on them from running catless is just awful, half of it wont come off but where it did, they shine again!
