Creating Custom Exhaust w/Hotchkis Sub-Frame Connectors

OK, I have the Hotchkis weld-in sub frame connectors and trying to route the exhaust along the passenger side of the vehicle with the subframe connector there is a major pain in the butt. How have others handled this issue? Is it possible to run a true dual exhaust in the center of the car like a Corvette?

I'm not familar with the Hotchkis SFC, but I dont see any reason why some of the dual set ups from the sticky wouldn't work. https://www.thirdgen.org/forums/exha...l-exhaust.html

I did a copy MW66Nova's duals with hedman headers, 2.5" s extentions, and full 2.5" exhaust with bullets. I also notched my tranny X member for clearence, but the exhaust still hangs 2.25" under the car under the tranny. I hit the S extentions alot at first, but they kinda self clearanced lol. Now I just kinda drag the bullets out back, or the H pipe under the tranny if I dont go slow over speed bumps, or the driveway. I still have the original V-6 struts and springs up front, so it sits a bit lower, and bounces a lot on the roads.

I have those subframe connectors...I dont know what size pipes your wanting to run. But i have 2.5 pipes running thru there. Its tight but fits if you run them side/side in the factory location.

I doubt you could get two 3" pipes thru there though.
