I want to get the Greddy exhaust but I had a couple questions about the metal. I know the muffler is stainless steel but what about the rest. Basically what Im asking is have these been know to rust because thats the last thing I want to happen for such an expensive exhaust system. I dont want to wait for the full stainless steel greddy to come out because I have know idea when it's gonna come out plus I heard the sp sounds better than the sp2. Please give me some helpful information.

 

I had a Greddy SP exhaust on my I30 for about 8 months. I drove it while I was in Colorado. During that time, the muffler did not rust, but the flange where the Cat and B-pipe meet had rust on it. It looks like exterior rust. I still have te b-pipe on my car, but I have a stock muffler now. I think the B-pipe portion is anondized steel...someone please confirm?

 

yes, I am fairly sure the B-pipe on the sp is not SS. I believe the sp2 is already out which is supposed to be all SS, but I would not be too worried about the sp. Many org members have the non SS y-pipe and I have not heard about rusting problems. Of course SS is better and will last longer so I would go with the sp2

 

I keep hearing people say they think its out but where is it. I dont know anywhere that sells is and redlinemax says its coming soon.

 

the b-pipe is aluminized

 

www.southwestautoworks.com has them

 

How come when you go to SWA and click on 1995-1999 and click the performance link, you see the sp2 for sale but it says 1995-1996 yet its in the 1995-1999 section. Does this mean it will work for the 1995-1999 years because I have a 98, or is it a mistake?

 

the only difference between the 96-97 and 97-99 is one has an o2 bung on the b-pipe and one does not. It is just a matter of pluging the hole if you don't need it.

Just call southwest autoworks and verify.
