As many of you know I started ,designed, owned M&K exhaust and sold it now about 6 years ago. The new owner and I have been discussing the need for a quiet good flowing muffler that is stainless and of the highest quality. So I decided to design a new muffler that mimics the original design and something that could be marketable. After much analysis of the stock muffler this is what I came up with. I will be offering a group buy in the near future on these mufflers. Please note these will be single out let only and I will still need to do some testing. I may offer a few good deals for those willing to test the completed mufflers.
Please note these are completely my design and will be sold with the m&b specialties name but others will carry the product like m&k.. |

So testing is going well and we new we needed to change tail pipe locations so that was just a confirmation.. Sound levels are hitting targets and the good news if someone wants it louder the old factory mods to a sport muffler work the same on this muffler..here is the feedback as quoted
" Ok Ben, Just got home from muffler install. First impressions: The fit finish quality is great. As I am sure you know the tail pipe does not match up to the stock outlet location. Height wise and angle, it appears fine, but exits considerable more outboard from stock. It seems to me that the muffler body will have to be shorter or the tail pipe bend radius will have to be very tight. I know you were trying to match the stock sound level. In my un-instrumented opinion, you pretty much did that. I can detect no significant difference in sound level or sound quality from stock. I suppose this will appeal to many, but for me, I want something more sporty when shelling out the bucks for an "aftermarket" muffler. Sorry, but if I wanted stock sound why wouldn't I just buy a stock muff? Weighs in at 18 pounds even. The stock Liefrentz (sp?) comes in at 21.5. No discernible difference in seat of the pants dyno readings. So looks like I am all set for the track day on Saturday. Plan is to run it up the flag pole and see who salutes. Wish it had a little snarl to announce it's arrival. Keep in touch. " |
