Maxx,
I did the muffler delete and I don't think it's loud, I was actually disappointed.
The stock diameter pipes and cats just aren't loud with the muffler gone, I'd hoped for a much louder exhaust note.
I don't know what loud is to some people but it isn't loud at idle in the least bit.
Cruising down the road it isn't loud, it isn't noticeable. It's loud when you gear down and let the RPM's slow the car as you get loud rumbling and pops making the exhaust note more pleasing, I like that.
If you like the note that the GT cars make gearing down on the track, you'll be happy with the muffler delete.
I'm going to get Sean Roe's Hi-Flo Ovals and run 3" straights out. The stock diameter pipes and cats just aren't loud like you would think. Now a Luxo-Car driver or what-not may think it's loud , but it's not.
If you got a little bit of gear head in you, you will like it but later on you'll be wantin to turn up the volume.
