My Audi needs an exhaust center section made. Something to go from the 3" downpipe to the dual 2.25" catback. My neighbors are tired of open downpipe sounds, and to be honest, I am too. Unfortunately, there's nothing off the shelf for this car, and most of the shops that I can find locally are more in the business of patching things vs. making something from scratch.
Open to any suggestions, but Columbus area would be preferred! Thanks!
I've heard a lot of recs for mad hatter. I've never used them but they may fall more in the patching category than full system.
My first thought is what did the factory do forward of that dual 2.5? If they merged into 1 pipe then maybe get that merge from a junkyard then ask a shop to do a simple 3 inch to whatever size factory is. I can see that Y part being the PITA if fabed up.
In reply to Stampie :
They split at the downpipe, unfortunately. This is the full stock exhaust
The new downpipe is a single 3" that runs along the passenger's side. The car came with an aftermarket stock-style rear section that I'm hoping to reuse since most full 3" systems drone pretty bad on these cars.
Needs the rear hanger repaired though
I've had repair / patch work done at Mad Hatter and they might do it for you. They're certainly more adventurous than most quick exhaust shops. The welding was good but when they needed a donut gasket they didn't have they tried to make do with a flat gasket and high temp rtv. So that wasn't good. Swapping that for the proper donut made the exhaust 100% leak free again so no worries on the welded part at least.
You do get to see an interesting segment of the Columbus population there. Not my typical bougie NW side folks.
Could you do something like this:

I'm assuming that either ur-S4 parts don't fit or nobody makes them anymore.
This kind of work is easy for me but I don't work somewhere where we encourage this type of work.
In reply to Pete. (l33t FS) :
Urs4 stuff fits, but the 200's slightly longer. Nothing crazy though
Either way, Stromung's pretty much the only game in town for this stuff anymore. But it's about $1700 for their system (minus downpipe), and they usually need a group buy to build any of them.
Just one more reason why I need my own welder. It'll happen one day.
If I were doing it, if there was room I'd suggest a short single in/dual out muffler to be the splitter. Splitters usually suck for flow anyway, and quiet/lack of drone is the goal.
Stainless Works is a great place out of Bryan Ohio - not too far from ya that does amazing work. Give em a ring.
