Exactly what the subject says. Any comments on build quality, looks, or performance. Also just want to confirm that I would purchase the one made for the 99-00 Si, right? Heres the link to the one for sale on Nopi, $350:

as long as its stainess steal the header should work out. Im not positive if the header will fit, I think you have to flip the cat. dont quote me though. a DC one will work fine if you cheap. what are you plans?

I don't plan on doing much more, maybe 50 shot of n20. Nothing else as far as cams or anything though. I don't think the 4-1's are really what I need. I was thinking comptech or greddy. My thermal cat back is a 2 and 1/4 inch exhaust so I don't see the benefit in a 2.5 collector on the 4-1's. Am I wrong in thinking this?
