Hello people I have a duplex sports exhaust to build on my Audi 80 B3. I have already found some, but my problem is that the ones I found are all from 1.8. I have a 1.6 with 51KW. My question is: Is there a duplex sports exhaust for the 1.6? Would it be possible to have the duplex ESDs or systems that are from 1.8 on registered for my 1.6? MFG
