I have TKC691 on my car: http://www.macperformance.com/macsto...o/cmroctbk.asp

I have decided that I don't care for the tips - they're not wide-open; they have a sub-wall in them. They look too large, IMNSHO.

That said, it was extremely easy to install once I got the stock exhaust out. The only confusing part was how to hang the tips. Everything else was a breeze.

The sound of the headers/cat/cat-back is nice -- not too loud. Good rumble. A bit too raspy for my tastes, but there's only about 200 miles on it; I'm sure it'll be very mellow after I finish the exhaust breakin.

I have a friend who has that cat-back and nothing else done to his TPI Camaro. The best way I've heard it put is a cross between Flowmasters (growliness) and Borla (tone). It does mellow out, but their older models also rust out. A quick coat of hi-temp POR 15 cures it. Overall, I can't think of any other $300 system that beats it's sound and flow. I've heard results of over 15 rwhp with this cat back alone.
