V6 Exhaust System:
The inside diameter of the V6 exhaust from the downpipe to the tips is 1 7/8" and the exhaust tips inside diameter is 2".
Here is my custom exhaust system:
Custom made total 2 ½” exhaust system consisting of; very high flow 2 ½” Random Technology cat , Muffler – 2 ½” dual Flowmaster 80 Series – this is the same muffler that the 5.7L Tunnel Port GM motor uses. This exhaust system is much better than the Borla system. 90 db loudness at idle !!!
