Overkill looks very good also, better than the others. What are your thoughts on going 91+ if I am keeping the car NA?

 

If you want to pay for it, it's pretty good. Going higher octane allows him to put a few extra degrees of timing in the car for you.

 

Looks like you got plenty of ideas here man but, ill put my 2 cents in anyway lol. I have a pair of thrush turbo mufflers on my monte along with a shorter resonator. i really enjoy the thrush turbos there just loud enough to get noticed and not too raspy either. plus there relativity cheap i think i only paid 40 bucks each for em.
