So I just got my evo x. I've been tryin to do some research on cattback exhausts. I don't plan on doin a downpipe or high flow cat. I am trying to keep the exhaust under 600. I was looking at the cnt catback but does anyone know if it fits on a stock cat? I know there are threads about exhausts, but they don't say whether or not they will fit a stock catalytic... any input would be great.

 

yes they should fit the stock cat.. and if i were you id spend the money for the full TBE youll be thanking me later only cause youll want it trust me

 

Trust me I've thought about the tbe, but this is a daily driver. I've modded heavily a few dsms in the past few years and I'm ready to just slow down my modifying days. But I figure if I do want to buy a downpipe and cat/test pipe down the road I can just add it to the catback.

 

Honestly with the Minimal gains of a "catback" it woldn't be worth the money spent. If 8-10hp is worth $600 to you. Not to me. If its a DD car, leave it stock and save your money. The OEM exhaust is actually quite good. Its the CAT and downpipe that are restrictive. I am in the process of switching back to an OEM exhaust after 4 yrs of a BR Turbo back. The po po are cracking down on "noisy" cars. BR exhausts aren't known for their quietness. So do yourself a favor, do nothing and wait for QTP to have a set up for the X unless they already do.
