vorsteiner exh + intake
hey OP, I was looking at exactly the same combo (GruppeM + Vorsteiner ti exh). I am also probably going to do the AAA short shift while I'm at it (since you have to remove the mid-pipes to install it, might as well do in 1 shot).
The setup looks great, and I can't wait to order now.
My question is, do you think you need a chip flash to make it all work well together, or does it seem to be pretty solid without a chip reflash? This was my main issue with my e46 m3, the last 1 year I had it I ended up doing the exhaust and intake etc etc, and never felt like I got it right, figured I needed to get the chip reflashed. Ended up selling (back to stock) before I seriously considered that though. What are your thoughts on this?
