Shorty Hedders
I was looking at the Dynomx 3/4 length but they have 1 1/2" tubes into 2 1/2" collectors. I was told by the guy who built my motor to run 1 5/8 -1 3/4 into 3" if possible. I want to run the new super 40's in stainless and ceramic coated hedders. I was wondering if the Headman's would fit the same as the dynomax ?
What are you running ?

No, I just put the mufflers on about 30 minutes ago. Thats what it looked like after two trips to borrow the pipe machine at a buddies shop. I had a few odd bends at the collecter, that was the toughest section to get to fit and weld up. I have a video clip of what it sounds like I can e-mail to you. I think these are 1 1/2 and 2 1/2 collectors I cant remember. That and 2 1/2 inch duel pipes is good to 400 hp and is enough for my motor. I'll be back later, its time to shut it down and put it to bed. I need to get back to work on the cab corners.

I thought that the dynomax were1 1/2 " and you could get headman in 1 5/8 "or 1 3/4" I really want the 1 3/4 " or 1 5/8 if possible.
