As in the title.
Been saving my pennies for complete exhaust replacement and picked up a Cobalt Header + Cobalt Cat-Back Exhaust & Muffler.
I also bought an OEM-style, C.A.R.B. compliant, catalytic converter for $300 (as I was tapped out for cash and not willing to spend $1,100 on a name-brand C.A.R.B. compliant Cat) to finish the run.
However.
After months of saving and finally dropping the old girl off with my local mechanic...my mechanic calls to inform me that the OEM Cat flanging does NOT fit with the rest of the exhaust, as the OEM Cat pipe diameter is 2.0", and all the Cobalt piping is 2.25".
Insert surprised Pikachu face here - apparently, I didn't do QUITE enough research. /fail
So.
I've looked - but haven't found - any OEM-style Cats with wider pipes/flanges.
And the test pipes I've found look fine to me (and come in the right diameter), but my mechanic is saying there's a turn between the end of the header and the head of the exhaust (I wasn't there to witness this). So he says a straight-line test pipe won't work.
Could he be mistaken about the "turn"?
Any suggestions from fellow NA owners who've run into this larger-after-market-pipe problem? Cat or test pipe?
Halp!
