hey guys. looking to do a full custom exhaust on my celi. planning on doing 2.25" or 2.5" piping, not sure which would be better though.im buying those ebay headers everyone loves so much,a magnaflow HF cat converter, and a generic/universal muffler ( 2.25" inlet, 4" tip). only thing though, cant seem to find a flex/down pipe to replace the original size and should i run a resonator or leave the stock one, at least i think its one, its more near the gas tank? any suggestions or description of how you run your set up would be helpful.thanks

I plan on doing the same thing - gotta get the headers powdercoated first and talk to a few muffler/machine shops for custom piping.
I plan to throw in a resonated test pipe and 2.5 piping all the way to the muffler (try to find one with a 2.5" inlet) But let me know how yours goes (or how it went considering the original post date )

Thanks!

I did mine about a month ago, 2.5" all the way back, no cat, with a Borla muffler. Only cost me 110 to get the exhaust done. Muffler was quite a bit more expensive but. . I would say go with a 2.5 in exhaust get a muffler with 2.5 inlet, and forget the resonator. About the flex pipe, idk what to tell ya. . I just kept my stock one cuz they don't make one for the 2.2 liter. . I want something different but I think that will have to be completely custom and fabbed up. .

well i had mine done for awhile now. i decided to go with the 2.25" piping, a oval resonator, under axle, and magnaflow muffler oval street series. it sounds great, well at least for my liking. its quiet ( bit louder and deeper than stock) then when you step on it gets more "throaty" sounding so so speak but still sounds deep and swell
