hahaha hummmm
to be honest, I think you’d be nuts to do that. Sebring are great quality, great sound, great flow (straight through perforated core). MTM are probably going to charge you $2500 for their mufflers (if they’d even sell them).
If I were making an RS4 exhaust, I’d make it 2.75", gentle x-pipe, sebring mufflers and oval tips to keep the RS4 look. Of course that has already been done by JHM and that’s why I know it’s succesful, so ethically I’d probably go back to the drawing board and rethink that.
Making an exhaust with that exact layout, which is basically a straight up copy of JHM, is tantamount to ‘reverse engineering’ a tune. Oh they did that? OK, I’ll do that. I’d put that ebwerks exhaust in the SSAC category of copycats. Maybe not a perfect replica…just different enough to not earn you a lawsuit…but certainly close enough that it’s not fooling anyone (weill…anyone that doesn’t post on quattroworld).
