I have a HKS Hi-Power Turbo exhaust on my S14 with Redtop SR. I like it alot. The sound is phenominal, and it looks great. However i have 2 gripes, which may not matter to some people.
1. The piping isnt full stainless like the Ti-C, but to me, it's not that big of a deal.
2. The rear flange is a huge 4 bolt flange and hangs down pretty low right next to the diff. I scrape occasionally on it, but i am pretty low.
