Diameter of Exhaust?
What's the diameter of the over the axle pipe on a stock LT1 car? I just might do a custom job myself.
|
I think it's 2.75"
|
Factory pipe is 2-3/4 and most aftermarket cat-back are 3".
|
2 1/2. I took the muffler off and measured. Thanks anyway guys

Wow....you sure that's a factory pipe? I always heard and saw that all 4th gen v8 cars had a 2.75" factory pipe.

pretty sure, the entire exhaust looks stock. I got the muffler off and measured the pipe and sure enough, 2 1/2
|
Your car single or dual cats, Pat?
|
single
|
The tailpipe outlets are 2-1/2 but the inlet should be 2-3/4 or 3". It actually necks down at the y-pipe connection too.
