Still debating on the cats....seems like regardless of the 0 power gains by not having them there seems to be an awful lot of pressure there, has to be restrictive ???

The power loss is minimal, and if legality is an issue...Which it is whether or not your state has inspections. There aren't any inspections where I live, but I added the HF cats a couple of years later to tame the loud exhaust a little. Now I feel as self-righteous as a Prius driver.

PS: what's up with the cascading thank you buttons?

Yeah, idk what's up with all the buttons....

My next concern with the "cats" is that I'm adding nitrous in 6mo-yr.
Seems cats and nitrous don't mix ? If that's the case, I'll leave them off.

Testing here at the shop on the dyno using a car making approx 500 rwhp the cats in or out is about a 4-6 rwhp difference.

Yeah, I'd forgotten, but several years ago I called LG and talked to George, about adding cats to my LGPros, and he sent me two short adapters, and clamps for free. I just paid for the cats. I've heard alot of people complaining about the furnished clamps, but I've never had an issue with those.

Found similar ones locally, installed last night after I removed the cats...worked much better !

Clamps are good, its the bolts in them that suck. Replace them with good grade 8 stuff and they work great.
