Evo X Problem After Exhaust install!!!
Hey guys I have a stock 2008 Evo X and today I intsalled a 3 inch cat back straight pipe to axle then 2.5 out to the tips no muffler. Sounds great but when im getting on it at about 6k rpms pulling hard it makes a studder like its hitting fuel cut of or somthing just for a split second then gets write back into it! does car need to be tuned for exhaust? overboost? any ideas will help thanks

Interesting, we installed a fully downpipe and exhaust on a stock EVO9 for a customer, we did a dynopull before and after. Stock eveything looked typical for the 9, but after the exhaust downpipe and test pipe, the thing went hard into the 17 AFRs above about 5K.. Anyways, the customer said he was gonna come back for a tune and was gonna park it.. Wonder if your having the same issue..

I'm running the ETS V2 cat-back exhaust, and the mufflers are quite small. I imagine your system is pretty similar.
You might also want to check your exhaust to make sure there are good seals with the gaskets. You replaced the stock gaskets, right? If the pipes aren't sealed correctly, this will have obvious effects on performance.
Good luck
