Helix up, down, and cat back
i have it, and i think its great
fitment is perfect and its just a beautiful piece, shame its under the car. but it is a little bit on the loud side, but if that doesnt bother you than its a great exhaust.

i DEFINATLY felt a difference with each part, i put on the uppipe, the down pipe, and the cat back on all at separate times, albeit a day apart from each other, and there was a dramatic difference each time. the uppipe and downpipe made the biggest difference, spool was quick and the power didnt taper off like it did with the stock downpipe, it held on pretty well towards redline. but as a side note, i have the catted downpipe so i dont know how much of a difference this is against a non-catted downpipe, so yea, but it is definatly worth the money for all the exhaust pieces.
and the uppipe does not have a cat, but unless your smog ref is going to take part of your car apart to look, he/she will never know, its only used for cold-start emissions anyways.

Everything you wanted to know about Helix products but were afraid to search for.
i got the catted downpipe because i could not stand the smell by going catless, so its a little bit of piece of mind for me, the legality of which i could care less about.
oh yea, the helix cat back is LOUD, but nice loud
it sounds very similar to hks exhausts i've heard

XkrazyAsianX- the Helix Up/Down pipes are great compliments to many catback exhaust w/ 3" piping, including the HKS Hi power exhaust. We have had several customer cars w/ that setup; they were all very pleased w/ the power gains.
