Possibility to make 500whp without having to do bottom end. b6/b7 s4

I couldn’t find a shop to do just flex joints either, they were all worried about aligning them correctly. Kind of a catch 22 since they can’t weld on them while the DPs are installed but they can’t align new ones when the DPs are out… However, they are available to purchase separately in various sizes (lengths/diameters) and just weld on, if you do find a shop willing to try. The shop would be able to source them quite easily I think.

Why the hell wouldn’t they tack them in place on the car and finish weld on a bench? It’s surprising how many fucking retarded shops there are out there.

Oh fuck I know… I ended up buying FI downpipes that needs new flex joints because they got squished in and I got the same answer… They’re not willing to attempt the weld since the DP are off the car and they don’t know if they can align it correctly. Kinda a noob question but would it be a problem lining up my Europa exhaust (2.5"diameter) to my FI downpipes? I’m not sure if the DP are necked to 2.25" or 2.5" but I’ll check that out today.

the downpipes are never necked on the B67 FI stuff…but the catbacks often are. If yours is true 2.5" it should be OK. They will have to figure out a clamp setup.

Make sure your Europa isn’t necked down because many of the catbacks that did come 2.5 had neck downs to mate up with the 2.25" downpipes.

That is correct.

Next week I have to cut off the necked down portion of a FI catback and weld on some 2.5" sections to make it a 2.5" exhaust all the way back. Should match up well with the V1 headers at are also going on the car.

Yeah I just found out that it is necked down… I currently do have stock DP on so that would make sense.
