I had em on my old mx. Same as the ss-autochrome ones, same weight and everything. One year driving in the winter, the secondary was kinda rusty looking. That being said, I never had a issue with them at all, they worked well and didnt crack/leak

yah the only real problem that your gonna run into, is the egr pipe doesnt fit. Just pick your self up a propane torch or even oxy/acetelene if you got it, and just keep heating the pipe up red hot and bend it till it fits.

yeah, but the cat has to be moved a bit further back, wich suck, as it now sits a lot lower because it has to clear the shifter linkage.

Hey I got a question
Do un-equal headers make the car sound kind of like a WRX? Some dude that I know that has a WRX says that his headers are all unequal that why his car sounds bad a--. I told him its because his engine is a flat 4 not a Inline 4 and that the firing order is the reason why it sounds so good

Infact, would having one stock header and the other header as a SS AutoChrome make the car sound any better then just having two SS AutoChromes?
