Does anyone with a 2000 acura rl know the id and od of the pipe before the muffler? I want tocut the stock muffler out and put a new one in just wondering if anyone knew the dimensions! Thank you in advanced!

 

I think my 96 have 2.25~2.5" ID. I don't know if they are different or not. The OD is for your liking. I had a magnaflow with OD of 3'' dual tip and it was loud, so I took it off after a few months lol. I plan to put back on the magnaflow with an aftermarket resonator and see how it sound like.
