Also, don't discount the Noblesse's performance. The Noblesse GD demo car (yellow) was considered the fastest Fit in Japan for a long time, even beat J's Racing's GD, but it got totalled a while back. The Racing muffler comes in two forms -- circuit and street. Both look the same, but the sound is toned down on the street type to meet inspection and also not to be annoying to local residents. I'm sure performance drops somewhat due to the extra sound dampening, but probably still quite good. The circuit type is LOUD, probably moreso than the J's even, and in Japan at least, you have to give a copy of your circuit license to Noblesse to prove that you're going to use it on the track only. Whether they care about that or not outside of Japan I have no idea, I would just ask if they'll sell it and leave it at that.

For the record, I have the J's 50RR, but have been following the Noblesse ever since it was being prototyped. I'd try the Noblesse circuit type myself if I were looking for a muffler nowadays as it's proven itself in regular racing and has a pretty regular history of track use.

J's doesn't focus on engine mods. They focus on suspension, handling, stability, and weight. Their best for Touge.
