Project _PTE_
Based on your experience I'm thinking my shorty headers and 300 cell 2ndary cats might hold me back....... perhaps kleeman mid-length headers and 200 cell cats next.
It never ends.
Please keep us fed with details.... we're eating it up.

I believe that you could go as large as (2) 2-1/2" exhaust pipe in the tunnel. getting around & under the Anti sway bar & diff. gets to be difficult.
Look to Blackbenz , He may have a post with Pictures . If I remember right He doesn't have any Mufflers and his exhaust is pretty LOUD!
If you are local you are welcomed to look at what I have while the car is on the lift, I still have the Carlsson ? Super sprint rear Muffler available , Single 3" in/ & could be made to Dual 2-1/4 in easily.

the original plan was to run 2 2.25inch pipe together through the stock exhaust tunnel until after it clears the rear suspension, then run the second pipe diagonal through the spare compartment through the trunk to the other tip. I am going to have a 4 inch pipe cut in half, have a 4inch section cout out of the spare tire well and then have the 4 inch half welded into the spare tire comp to make a new tunnel for the other pipe.
i am however going to price out the other spare tire comp that can be ordered for a cost comparison now.
also found a carbon fiber insert for the stock bumper that allows 2 new tips so i gotta price that out versus cutting and repainting the stock bumper. Something tells me cutting and painting will be cheaper but that insert has a much better look and i gotta weigh out the extra cost versus the more professional looking install when its finished.

1st - pic is a shot from the muffler to the cats ( Don't mind the shop, it's a mess)
2nd - pic is a passenger side B/S anti sway bar. as the 3" exhaust passes under loop in the anti sway bar ( Notice I used a MB exh Hangers & Grommets ,to keep the vibration / noise to a minum )
3RD - Left side pic of the passenger exhaust , under the B/S anti sawy bar
4th - Pic is the Drivers side 3" exhaust pipe as it passes under the anti sawt bar
5th - Pic is a shot of the pipes tucked up nicely and can not be seen from as the car sits . More to come as I dress out the bumper fit & install the rear hangers.

3" pipe and True duals , something seems to be holding the car / engine back , Not that 435 RWHP isn't enought. The last time I had a HP issue . It was resolved with installing the Klee headers. Hopefully This exhaust set up will Improve over the Single OEM 3"

Well I finally got to the Track, To test out my updated ECU & TCU I wanted the RPM limiter raised to 6800 rpm . But It seem to only go up there 1st thru 2nd . 1 too 2 shift is good & firm in dyno mode. I have the Blue top solenoids, and did a Complete trans service. ( no metal or clutch plate particals). just a 1000 miles ago. 2nd to 3rd , the shift hesitates badly. so bad
everybody asks why I am letting out of throttle. I'm using 275/40-17 Mickey Drag radials. But this also happens withStreet tire is sport mode.Here are some videos. Every body has good comments on the Exhaust

Exhaust is not too loud at all. Very streetable.
I wonder if a taller tire would keep you out of 4th gear at the top end?
Thanks for the film treat! It's making the wait for my ride that much harder!!!!!!!
