Guys,

When I bought my 88 IROC with 5.7 TPI, I quickly learned that it had a gutted cat. Unfortunately, I have to pass an emmissions test in my area so I knew that I had to get a new cat. I researched Random Tech, SLP, Catco, and stock and decided on the Random Tech for my car.

The new cat was installed Thursday and I have been test driving. When compared to driving with the gutted cat:
1) The car sound has less of an "edge". I have a Dynomax Cat-back system and the change in sound isn't all that much.
2) The car seems to pull harder in lower rpms. For instance, I find that under moderate accelleration, the 1-2 upshift (700R4) is now more likely to produce wheel spin on dry pavement. Wet pavement magnifies this.

Overall, it feels like it has a little more torque.

I couldn't be happier.

FYI

Oops. Forgot to say - I passed emmissions by a mile. Not bad for a 90,000+ engine.
