I'm considering these two exhaust, and I don't know which to go with for my application, so I figured I would leave it in the hands of the s2ki community which do you perfer and why? Pro's/con's

HKS Hi-Power vs. Greddy Ti-C


2006 Bone Stock


Thanks in advance

What pipe size is the TI-C, and weight. From your research did the TI-C gain any HP?

HKS Hi-Power actually loses power... how do I know... stock AP1 vs Stock AP2... AP2 pulled top end...

when adding HKS same pull over a week later.. done 3 times... from the same speed AP1 pulled the AP2 up to 120. About 1 1/2 car lengths.

That's what I was worried about, I heard it doesn't add anything and sometimes hurts. . .


Is it true you need ap1 hangers if installing on a 06?

There are so many variables that could have come into play it's not fair to blame it on the HKS.

All I ever hear is that the HKS loses power, but I've never seen a worthy dyno plot to prove it.

The truth is that the HKS may not make 20 whp, but any gains or loss are not noticeable over the OEM exhaust. It might be a tad lighter, and it sound 100 times better and that is all we should say about it.

sorry but all i read was ass dyno talk ..

i had the hi power ..alot difference from stock

sold it to my friend which has an 05 ap2..and i couldnt keep up with him anymore.

Revenge

so what is the main difference between this and the EVO2 they sell for our car? Is it just lighter?

The HKS sounds great, but the quality isn't great. Even the newer ones can have issues.
