I bought mine used and never have an issue with it. Had it on for over 6 years now...who knows how long the original owner had it. What I liked about Remus is that it comes painted in all the places that gets welded, which is where things usually get rusts. Best tips ever made for any exhausts, IMHO.
Powers1,
To me, Remus has a better quality "feel" than Supersprint. I had Supersprint on my MCoupe and it didn't look top quality...sounds great, but it was loud. Ultimately, I grew tired of the drone and got a set of Remus for it as well. Now both of my cars are running Remus

If I can find a set of Eisenmann for the coupe, that will be my next exhaust for it
