Does anyone have any 3" inch exhaust system they are willing to part with? Do not need mufflers, pretty much any shape.
Have a few ideas I want to try......

thanks

I've got a complete low mile Borla Cat back including resonator. Its in great condition but appears to be 2.5" O.D.

Borla was avail in 2.5 and the 2.75 Challenge system

Corsa is 2.5

Stainless works, Desert Development and B&B are 3"

Magnaflow is also 3" but you need the LT1/4 exhaust then get the headpipes fitted for our cars

Yes I am aware.
I have a very nice 2.5 inch corsa and will be needing a 3 inch B&B.
I would be willing to trade my corsa as well, it is in very good shape and has had the H pipe widened up internally to the full 2.5 inches. sounds deeper and has more power than stock.

A 402 with stage III cams.....
ported heads, big valves, ported housings and siamised plenum

should get the cams in in a week or so, can't wait. I am sure I will be beat up by a million little things as it starts to go together... :)

still looking for a 3 inch system, B & B is preferred.....

will be selling a Corsa once the 3 inch is installed

thanks John

Desert Development made a 3 inch system but I don't know if they still exist or if any are around. Huge drone/resonance problem with it but otherwise fine. See Marc's 2011 article on c4 ZR-1 exhaust systems--Bob
