so have a 2004 lancer ralliart and was wonder what was the best aftermarket exhaust to go with for it? I was looking at the srs r1 but couldn't find it for the ralliart. Also what about the o2 sensor that's plugged into the exhaust does it go into the aftermarkets?

From what I have seen, a lot of people tend to go with a Magnaflow cat back.

i think magnaflow is the only company that makes a cat-back for a FWD lancer...lol

and yes you need your oxygen sensors plugged in, that should be a given.

(might be looking to purchase) i've heard that they sound pretty good anyone's opinions on this as well? also just out of curiosity has anyone found videos of stock exhaust vs aftermarket? horsepower and what not? thanks

There is nothing really good as aft mkt "OEM" replacement.. but find the stainless OEM used on the 05+ and it works nicely for those with the 04 (like mine) that had rusting exhaust.. or go to speedy etc and get parts bent in alu pipe using 2.5" diam. saving $ vs fancy aftermarket setups.. unless it's turbo.. and that's another ball of wax lol
