Well, I guess this Eddy Catalytic catted downpipe gets the award of looking most like the OEM downpipe, but c'mon even going direct to the Stone Exhaust website it doesn't even mention if it is a 200 cell or 300 cell specification.
All things being equal, when I pull the trigger on a downpipe I think I'd go with the very well reviewed evolution racewerks high flow 200 cell catted downpipe which is even available in 3 different finishes (brush, polish, or ceramic thermal coat black). Additionally, the catalyst is metallic instead of the lesser quality ceramic. Most all the joys of catless without the stench or check engine light.

ER downpipe might throw a CEL, Eddy downpipe guarantees no CEL. If you car is tuned and your tune hides the CEL, get Evolution Racewerks. If that's not the case, your better off getting an Eddy pipe or something similar (Active Autowerke or CG Precision)

Hello, 1-We do not remove comments, it's disgusting of you to post that claim without even checking with me if it's true. The only time's posts are not approved are if they violate one of our rules. 2- this is a stone Thread, not evolution racewerks so you might be mistaken between the 2 brands. If you bought an Evolution Racewerks downpipe relying on comments from this thread, then that's a mistake and you should delete your post.
