 MB 45 exauhst
Went out and ran my new boat and motor yesterday and all I can say is WOW! The only thing that I dont realy care for is how loud this thing is, it has the stainless dual pipes on it I love the way it looks and the low profile of them especialy for being on a gator hide but want some thing quiter and still low for duck hunting this fall what are my options?

 Re: NB 45 exauhst
Run the MB crossover with silencer or check into the MarshMellow exhaust. Either should be quieter than the twins.

 Re: NB 45 exauhst
the silencer doesnt help much on the crossover

 Re: MB 45 exauhst
off topic just a bit for a second, is there anything you can do to the stock exhaust to make it flow good but keep its quiet tone. Im thinkin this crossover pipe might be a little too loud for duck season and scouting for birds.

 Re: MB 45 exauhst
Thanks for the ideas might try the cycle baffles, but do they cut down on the flow

 Re: MB 45 exauhst

 Re: MB 45 exauhst
Dukkilr,
Did you notice any throttle response or performance loss with the restriction?

 Re: MB 45 exauhst
The throttle response felt the same Just running it in my shop the only differance I could notice was the noise level, plan on running it this weekend but I dont expect to notice any differance.
