Just wondering if the Hks hi power exhaust or the carbon ti will bolt up perfectly to the helix 3" hfc? Thanks Also if anyone knows if the hks exhaust is quieter then the Greddy?

 

I was told by gruppe-s that they bolt to HKS exhuast just fine. However it may not bolt to stock dp. ANyone know for sure about the dp? HKS is definietly quieter than the Greddy Ti. I ahve the carbon ti and my friend has the greddy ti. I believe the Greddy is slgihtly voer the legal dB limit. HKS is safely under the dB limit.

 

I have a Helix high flow cat bolt up to my HKS Hiper exhaust

Yes it does. I have a helix downpipe and Helix testpiep bolted up to a HKS carbon exhuast with no problems.

 

any difference between the carbon ti hks and the other hks models? as far as sound and performance? only difference i see is the cosmetic.

 

The HKS hi power is made of mild steel. thats the main difference besides cosmetics. ANyone know if Helix HFC bolts to stock dp?

 

The 30th anniversary hi-power is fully polished stainless.

 

can someone verify if stock dp will bolt to the 3 in Helix HFC? I was going to buy one, but the vendor said it wouldn't bolt. can someone verify?

 

I guess my hks 30th anni doesnt bolt up to the helix High flow cat, since the hks tapers down at the cat end making it too small to line up with the helix high flow cat. I went with my stock catalytic converter. Anyone else get the hks 30th anni to bolt up to there helix?

 

My hks 30th bolted up to my Helix cat just fine. No leaks. Even with the taper, it'll bolt up and seal.

 

Mine bolted up perfectly....but some advice.

Make sure you get all NEW gaskets. The cost a few bucks, but will guarentee NO leaks.

Throw away your stock crap exhaust bolts and buy some new stainless ones. They will look better to match the exhaust and will NOT rest like the stockers!
