Heres one for a 3.5 cc engine. Anyone running one of these pipes? Are they any good.
Thanks

I don't know that they are "new".

I talked with MAC awhile back about them, and they said they are just their stock pipe, with the can added onto the end of them. They have two versions, depending on if you are running the high nitro, or low nitro 3.5 pipe.

I have not tried it yet...but probably will sooner or later, if they keep calling me out for being too loud. I would imagine the performance would be very close to their normal pipe, since that is what is under the can.

Looking at my notes, if your current pipe is 1 3/8 at its widest point, the muffled equivalant is the the MAC 1328. If it is 1 1/4, the muffled equivalent is the MAC 1327.

I don't think they are all that new also. I bough a 7.5 muffled pipe as well as a 13cc muffled pipe a long while back. I'm happy with the performance of the pipe with the addition of the muffler. The first thing I noticed is how well it improved the tune of my engine. Must be from increased back pressure.

Sean, which pipe are you running. In marine Mac makes 3 different non-silenced 3.5 cc pipes.

I have not pulled it to measure it yet...but plan to so I can go to a muffled pipe when I swap motors out later. There is also some aircraft 3.5 pipe(s) too.

I am running the one Twisted Liquid carries. I think it is the part of theirs I have on my boat. I asked James once which it was, and he said it was the high nitro one...
