Hi-Flo cats

I notice that very few of the members here have hi-flo cats. My experiences in the past show that a hi-flo cat can do wonder on these types of cars...I'd guess about 3/4whp with the cat alone, coupled with a catback you'd probably gain up to 10whp...views on this???

nightowl, where did you get your thermal cat-back and how much did you pay? If you don't mind me asking.

I've heard that with a bit of grinding and polishing the exhaust manifold is fine. The flex pipe is, I'm told the real problem in the exhaust system.

no kitty....

I removed one of my cats and my exhaust resonator and noticed a huge difference. There is though, not much you can do about the stock header design(2.0 Protege).

I'm thinking about getting this done, but I don't want it to be too loud, I mean obnoxiously loud. Did it end up this way? I might get a high flow resonater to help it quiet down. All this will be done when I get my CheckPoint cannon style muffler installed..

The guy who did my exhaust told me the same thing too.
