Just got done modifying the borla exhaust with a borla muffler cat test pipe and installing a few flanges to swap out the muffler as well for the new muffler delete pipe. I am now left with a straight shot from the turbo a full 3" wide in stainless with only a slight graceful bend for track days... Can't wait to get the map done for C16 and the muffler/cat delete combo on the gt40 at some respectable boost.

Here is a pic:

Basically I have now a 3" straight pipe from the turbo to the back of the car for track days...

 

damn thats nice , it must be loud as hell!

 

I found the opposite to be true (mufflers shape the exhaust sound even more and are louder that muffler delete pipes) esp. on turbo cars.

Nice work btw
