I heard the greddy evo's have problems w/ rust. How common is this? Is it like a guaranteed thing that it'll rust? Does the rust affect anything?

 

The piping isn't stainless

 

Actually Greddy has a version 2 of all thier exhausts that are stainless all the way through, these exhausts do not rust like the version 1.

 

well, i might be able to get a used one. so i was wondering about the rust problem. it's been used for almost 3 yrs now, should i be expecting any problems? is it a pretty common problem w/ the evo's?

 

If it is 3 years old I'd probably look elsewhere... chances are the muff. is blown or there will be some rust on the piping. Just examine it closely and shake the muff. and see if it rattles before you buy it

 

I have had mine for not too long and it some rust. Still sounds bitching though.

 

To prevent this rust would it be good to spray paint it with some high temp heat spray paint? Just an idea. I have one too and was goin to do this which is why I want to know.
Thanks!

 

so a 3 yr old evo isn't worth buying?

another exhaust that i was considering getting was an N1. I live in California, so you guys know how strict the damn laws are here. If the only other mod I have is a typeS intake, would the N1 be under 95db or no?

 

i think the n1 would be pretty loud. my buddy had one for his b16 si and it was loud as hell.

 

hmm..so does rust on the piping affect the performance at all ? or what does it affect?

 

don't think it would affect piping, but i guess eventually it could eat throught it. damn car cancer.
