N54 Which downpipe do you recommend? Which to avoid?
I had an exhaust leak from where the front turbo bolts to the stock downpipe so after pulling one out I decided to pull both and just replace them.
I am looking for recommendations on a good place to get down pipes from. I don't care about brand name, etc. I just want one that fits well and won't rust out or crack. |

I'd say the MMP currently on sale for $249 is the best quality for the dollar, right now. Othwrwise, VRSF is a good budget alternative that's been proven, and most have had good things to say about ARM, also a low cost option.

I have VRSF and its been great.
Stay away from no name ebay pipes. Ive installed one a couple years ago and fitment was terrible. Its still working but has a dent pounded into it for clearance.

That's good advice. I was literally thinking of getting the eBay pipes because I figured what's the difference? from removing the old ones I realize how critical fitment really is. I was actually going to try to fix this exhaust leak between my front turbo and downpipe and do aftermarket downpipes sometime later. After the hassle involved in removing these downpipes including all four bolts to the rear exhaust breaking off; I decided to do aftermarket ones now so I don't have to do this again. I can only imagine how much of a bitch it is when the pipe does it even fit right. I guess I'm also going to replace those gaskets where the turbo meets to downpipe. It looks like most people do not replace those but that is right where my exhaust leak was, around the V band. speaking of never effing doing this again any recommendations on a cheap place to get the front O2 sensors? I've got solder and heat shrink so they don't have to come with the factory plugs If someone knows of ones that are compatible.

Yes replace the gaskets under the V bands, they are cheap. As far as being a PITA, after a few goes this can be done very quickly. just takes a little practice.

the gaskets on the turbos look like they're on their pretty good. I haven't tried to remove them yet. Well they just pop off or will I have to scrape the bits off? just trying to figure out how much time I'll have to set aside to put them back on. I'm going to try to get some stuff done before the new pipes arrive.

Vrsf had issues with xi v1 downpipe as they were early adopters and they fixed them quick. Their were alot of haters when ss and ar were the only game in town and vrsf cut price in half. Either was vrsf may have had couple hiccups on early batches of products but he has perfect customer service and will go above and beyond. I know you already made your purchase I just wanted to make sure people dont get misinformation. The s55 platform is a little more sensitive to requiring a flex joint "supposedly I have no personal experience saying so" but I think Wagner is probably the only one that has a flex joint on this platform.
