the SW can is a great can. Not to loud and alright weight loss. For the money though there are a few other cans that will provide you with a greater weight loss like the ultra q, super q, and MBRP. The ultra q is pretty quite while the super q and MBRP cans are a little louder, but sound great.
Looking for advice on the best can for a stock 09 M8. I live and ride in MN and will also ride in the UP and Idaho. Plan on keeping motor stock for now. Do not want to loose power just for sound. Looking for the happy median on power/weight loss/sound.
I had a mbrp can at first fit was poor always leaked and it turned color.I returned it and got an slp.The fit was perfect sound was great and still looks like the day I put it on.
