Thanks fellas.

Honestly, I love greddy stuff. Tanabe is suppose to be quieter and all, but their tips are ugly IMO. The double rolled tips are too thick and the way the off set the tips on the pans takes away from the exhaust. Sure it gives some ground clearance, but not enough to matter. My car is lowww, I doubt my resonators will scrape unless I'm going over some serious speed bumps.

Just go with a greddy exhaust. anything below 3k you hear slightly inside the cabin, about 3k... silence. Outside its a little louder then a G35 (I've always loved how the G35 coupe sounded stocked)

 

I've loved my Tanabe MT. Definitely not the loudest but my priority was to avoid in-cabin drone. Great sound when you punch it--and the tips integrate very nicely with the rear of the IS (IMO)... Got it from another member in the classifieds for $400 + negotiated shipping cost
