During cold morning starts, I can smell a little exhaust fumes in the interior for just a few seconds (20secs) and then it's fine. Most likely just a small leak.
Also, there is a crust of rust on the lower portion of the muffler tips. I was only curious to know what options are available for 02 Q45?
I'm a big fan of Borla exhaust but they do not have a system for my car. I'm looking for an exhaust that is quiet and freer flowing if possible.
Thanks!
where in NOR CAL are u?I'm in sacto and drive to san ramon a couple oftimes a week.THe system acually works very well......making it difficult to improve on w/ aftermarket. some of us have removed the rear muffler and have stright pipes to the tips. a couple have experienced slightly better milage as a result.What I find interesting, on the 03 M45, they have a slightly different exhaust setup than the 03Q45. given the similarity in the two, I was surprised that they engineered a different system. Particularly the duals uot the rear on the M. And the M has less performance (supposedly).WHy did they spend the money on 2 suitcase rear mufflers??
Brian, did you see the post on the M site where the guy went pure dual and the post evolved into a discussion on 'cross-over and X pipes".
zer...e-pix
On the F50, right past the cats, it Ys into a single resonator the ys out into 2 small mufflers and finally duals into the single suitcase muffler.If I remember, the M didnt have the single pipe resonator.....
