Okidokie so I have a 00 Si. Tired of my exhaust. I hate it quite frankly hit the gas and it sounds like a pissed off cat corralled in a corner. So my gf just purchased a new Si and the exhaust is sex . Its the exact sound I want for my old and decrepit em1.

I did the research and looked around on majestic honda and did some eyeballing and tape measuring on the gfs car (much to her irritation she thinks im trying to sneak parts on there) and I'm getting ready to build my own and from what ive seen the midpipe is approx 2.24" (57mm) at the catalytic converter and then 1.99~ (50mm) at the end of the resonator and then ~2.5 inches (60.mm) at the beginning of the muffler.



I had a couple questions
1. Is the pre muffler (8 on diagram) muffler straight through or chambered like the magnaflow xl?
2. Is the entire midpipe 2.25" until after it leaves the resonator? So does it continue to be 2.25 until at that flange were its 2.0"?

Thats all the ones I had for now. I'm planning on using my DC header and a resonated test pipe (good quality one) with a 2.25 midpipe and an 06-09 Si muffler. I know other people have tried this and I took a stab at it once before but i used a 2.5" pipe before and it sounded like bahoojo. Yes, I said bahoojo. Any advice helps. Thanks

i tried that actually. funny story. She came outside and found me laying under the car with tape measure and tool. I **** you not she got in the car and put it in gear as if to drive off. Burnt the **** out of my arm too cuz she had just driven the thing (i was wearing nomex mechanix gloves before you ask how i handled the pipe) and she told me if she found out i went under her car again she'd run me over. She's country too () so i'm not going to test her conviction. Anyways long story short, its not a viable option.

put the car up on jackstands or take 2 tires off. od disable the engine by unpluging the fuel injectors, starter, or coilpacks.
