Just had Belanger headers and r/t cats(ceramic) installed...my impressions...
I have a Corsa 3" cat back, with the cross over tube.
The idle sound is much better...louder and deeper/raspier...can even notice a slight lumpy cam at idle...
Decell is awesome...loud snaps/pops...
3000 rpms and WOT up to redline...Very Loud and the Performance SOP gain is Impressive...
Cruising on highway...much "quieter" than before, and runs MUCH cooler on side sills and inside cockpit...heat shields on Headers.
Better and smoother throttle response!
Upon startup in the garage, I used to see condensate "dripping" out of the 4" chrome tips, Now It SPRAYS out 2 feet! That should tell you something.
Will get sound files and videos soon!
Very Pleased!!! Sorry I didn't do it sooner!
TT or S/C next!
