Default Exhaust question.

ok, im wanting to know the diameter of the inlet pipe on the stock muffler of a 2000 camaro SS. is the inlet 3 inch or 2.5? im wanting to know because my car already has the slp dual dual tips but not the muffler. and versus buying a cat back for just the muffler, im gonna try to purchase the dual/dual muffler on its own but SLP said to make sure my inlet was 3 inch. not sure if it is, dont have calipers to tell. can anyone help me out?

Should be 2.75", at least that's the i-pipe diameter.

actually the dual dual is a 3inch system...figure out if its just the tips or if its the factory dual dual and someone replaced the muffler along the line. i know my car had the dual dual and someone swapped the muffler so im in the same boat.

If your car did not have the OE dual/dual then your I-pipe is 2.75".

If you're unsure because the muffler has been replaced, check the I-pipe. If it is a solid pipe then it's 2.75", base exhaust and someone changed the tips. If it's clamped together before the bend over the axle, then it's probably the OE dual/dual that's 3", and someone just swaped mufflers.
