Parts: 3"in/out Dynomax bullet, 3" cut-out

Idea: think of a borla system...

That seems a little bit like the "dynomouth" exhaust people have been making with a cutout added. A friend of mine did almost the same thing.

 

I did the same thing too, but with a 50 series instead of a bullet.

Sounds awesome, and works well. You'll probobly want to upgrade to a bigger I pipe later on, but for now it works well. You can tell how well Flowmaster mufflers scavenge exhaust, because at idle, there's no exhaust coming out of the open side.

Edit: You probobly won't even need a cutout, unless you want to cap it. They just cut a hole in my I pipe after the axle, and welded the open pipe up to it.

 

Since you're putting a bullet muffler in there I'd have to say the cutout is pointless. For one thing, opening the cutout isn't going to provide you with any more power since the bullet muffler has a straight through design. Plus, whether the cutout is open or closed isn't going to sound much different with that bullet muffler in there, it hardly has any packing material. Now if you had a Flowmaster/Dynomax/Magnaflow/Hooker or something like that, it would sound different.
