m4 exhaust

Have been wanting to replace the exhaust for a while now and been looking around, im really liking the m4 slip on can (the noise as well as looks) n wondered if anyone has one or had any experience with them?
Have heard that some ppl say there too loud?! Is that even be possible!!

Cheers

Yep got one although i've got a full system. Wife reckons its effing loud, don't notice it myself. the house does vibrate a little bit when its out back ticking over.
bike revs freer with it as well.

Depends how friendly your local mot station is I guess, I've never had a problem with it in the last four years.

Bike was dyno'd bout an hour after it was fitted and was running just shy of 72bhp (about 6 or 7 bhp up on dyno testers expectations) on a dynapro which I have heard can give lower (more accurate?) readings than some dynos (although that is just hearsay).

i've got 2 Minitwin bikes both with M4 full systems and the quality and dyno results are superb. Well made. Excellent Product.
