A question! do you hsve to run premium? Or will it run fine on regular?

I've been hunting around...Autoanything seems to have the widest selection right now..I might just call them...

I run it on regular, have tried premium and there's no difference in anything.

You can always drill a few holes in your muffler. Worked well when I was a kid. Now I like them as quiet as possible.

So no spark knock on regular? Good to hear, researching next truck.

I havent put one on this exact truck but have done everyone I have had. I sure do like the sound of flowmaster,gotta get a high flow cat.or take it off all togther. But magnaflow,borla are also some good ones. X back systems or the cheaper route single inlet dual outlets.

It has 2 cats, they ARE HIGH FLOW!! The GM cats have been since the mid 1990's, and it will actually run worse with out them.
