I’d think there is more “science” involved to properly size and install a crossover to make it effective. But, you could just do it, and if you aren’t happy with it, remove it and weld a patch back over the holes. Since they holes will be on the inside you won’t see them patches.

Cheers!

I think I had them listed here awhile back for $40 or $50 shipped. I'll do $30 for ya.

Thanks man. Tried PM'ing you, but your inbox is full.

I'm thinking of picking up a set of V&H Straight Shots slip-ons, which have the crossover pipe bungs already installed, and using them with the V&H head pipes, and stock crossover tube. Without the heat shields installed on the slip-ons,they are about the same the same diameter as the head pipes with heat shields installed. I think that will accomplish what I'm after - a crossover system with staggered drag pipe look.

If that all works out, I will do comparison dyno runs to see if there's any significant performance change for better or worse. That will be in the springtime.

Fingers crossed it all works out and I make some gains. Worse comes to worst, I'm out a few hundred bucks to satisfy my curiosity.

Cheers!

I'll empty again.
Here's a pic. They're 8" long, 2" in diameter, and fit snuggly in the muffler body of the straightshots.

Baffle

What an interesting design! I'd be willing to A/B them with the TTIs.

Thanks.

Cheers!

Khromewerks and now Thrashin calls them part of an anti reversion baffle. They seem to diffuse pretty well and have a nice deep tone. Those are inside another perforated baffle in the khromewerks and Thrashin.
Post your results. I'm curious how they really do in that setup.

I will for sure. As I mentioned in the PMs, I'm going to do a shootout with the different exhaust configs (starting with what's installed now: V&H Straight Shots full system, no baffles, with TTIs), and go with the one that performs the best.

Cheers!
