I had one on my GTA for about 2 days with the same setup and a gutted cat. Thing was quiet as hell. Only thing gonna make it louder is a different muffler. Run a real 40 series or a V-force by Flo-Pro. They both rock.

the 80 series has sort of a raspy loud to it, the original 40 is the loudest since the super 40 came out, or so they say. i dont see how it can be quieter than the original 40.

thinking of maybe changing the muffler to a dynomax bullet will that be louder and still keep that agressive tone?

I wouldnt sugjest a bullet muffler unless you seriously want a rediculously loud car. They arent called race mufflers for nothing. I know a few people that bought the bullets and got rid of them the next week.
