hey guys im planing to get an hks 30anni cat back...i cant decide what kind of downpipe i should get...i was thinking of going hks being it is an hks cat back...and i want something smaller than a 3" but bigget than the stock...any suggestions of any good and efficient downpipes?

 

If you're gonna keep the stock cat and run the HKS 30th anniv catback, then the HKS 2.56" (65 mm) DP is one of the better, but pricier options (part # 3306-SM002, MSRP = $445).

If you intend to replace the stock cat with a 3" test pipe or 3" high-flow cat, then there are probably more/better options than the 65 mm HKS DP (the HKS would still work fine, but you may be better of with a full 3" TBE).

 

im in the same situation and i think im going with the helix 3" dp, a 3" hi-flow cat, and the 30th ann.

 

I've heard the Helix dp's rattle and don't fit all that great. Anyone have any thoughts?

 

Just got my dc sports s.steel downpipe that eliminates cat put on saterday. Let me tell you this thing is light, and is top notch. Fitment was perfect, sounds and looks great. You can find them for about $240 shipped, its a great bang for the buck.

 

is it true that the 30th ann. hi power tapers down to 2.5" at the cat?

 

I sure hope this isn't true being I'm about to have one of these installed soon...

 

yeah, can anyone verify the rattling?

 

I have the Helix DP, and I have no clearance issues, or rattling. I have heard some people do, but it could be an installation error, like not tightening the DP bolts evenly.

 

consider tanabe DP - it's bigger than hks dp and the $ is just rite.
