Exhaust Update...
The car was one of the first 4L80e swaps into a C5 so a few things were a bit dated. The main one being the exhaust. From the turbos back it was a 2.5 inch setup. The x-pipe had about 7 (not joking) bungs welded in it over the years all at incorrect angles. When it came time to go around the fab aluminum tranny pan things got tight and who ever built the exhaust chose to scallop the pipe down to almost half thickness in order to clear the pan corners. I'm honestly amazed the car runs what it runs with such a huge restriction. From there the pipes went up and over eventually ending in a 1-off set of mufflers made just for this car by Borla. These mufflers flow a ton, and are insanely quiet. Too quiet for most peoples liking. Like, as quiet if not more quiet than a stock C6. Over time the hangers on the can's got trashed and they were barely hanging on there so that had to be fixed as well.
So...here's what it went in looking like.

Now, time for the good stuff. We went with a full 3 inch stainless setup using all V-bands for ease of removal. The whole thing was built sectional so just pieces I needed to could be removed without disturbing the rest. The car is a Hot Rod Drag Week car so roadside repairs happen. Dennis was able to retain the mufflers and utilize the factory mounting points at the tail of the car. One bolt on the V-band and the cans come right off. Eventually extensions will be made for when the muffles are removed. The whole update was not cheep, but its top notch work, and I don't mind paying for quality.
So, here you go....

Not sure if the car will gain some power or not, but that wasn't really the point anyway. Only time will tell I guess!

Finally looking as it should. That old x-pipe was incredible. Lol.

Nice craftsmanship on that exhaust. Well done.
