My car has been at Fabspeed (
www.fabspeed.com) being used as a template for a new exhaust system. They already manufactor a Tubi like system that replaces the rear mufflers and increases the growl. If you look at the entire system though, you'll see there's a center resonator, infront of that a set of secondary cars (not required in the US for emissions since they are AFTER the second set of O2 sensors), and a bend in the pipe that pretty much flattens it out completely.
The new system sounds amazing and looks great. The clearances are no issue and it looks like the flattened out pipe is just the factorys way of being extremely conservative clearance wise.
Fabspeed also has a complete system from a warranty car from headers back that they've been experimenting with.
Car goes to the dyno tomorrow and after any needed tweaks, will go into production.
Rear mufflers w/SS tips: $1495
Center Resonator bypass kit (set-up still with an "x-pipe" design): $1000
Secondary CAT bypass pipes, $1890
All pieces are polished SS and drop in fitments, none of the above void warranty
All three can be used individually to tune the sound to your liking or order all three togeter and get a $300 discount or free local installation in the Philadelphia area.
If there are 5 or more people interested, there are 2 options for new headers as well (count me as #1 in line). This might or might not affect the warranty depending on your dealer and the problem since you're replacing the CAT. Car is still emissions legal and guaranteed no check engine light issues
opt 1. Take existing system, replace 600 cell count CAT with 200 cell count CAT and clean up some of the welds and bends (there's a 90 deg. bend in there!). $2000
opt 2. Complete new header with F1 style collector and 200 cell count CAT. $4000.
I will post pictures in a few days but while they have the car, wanted to see how many might be interested in headers, so if you are (or any of the other pieces), please PM me and I'll start a list for the group buy. 5 or more people upfront they'll knock 15% off the headers. 10 or more people and they'll knock 20% off
