I'm looking to have a pipe built for my 131 Dyna w/B-2 heads.
I'm in the process of having Burns stainless spec a pipe for me but I am going to have to get someone to fab it up off the plans I get from Burns. I looked at SPF website but I thought I would get your thoughts on your pipe once mounted.
Are you going to get it dynoed after?
It don't look it but is it baffled?
It comes off the head at 1.75 immediately goes to 1.88 - 2in, then again
To 2.125, 3in collector, , 4.5 muffler, with 3in. Baffle, and 4 in reverse megaphone exit.
Its not equal length front is 10-10-10. Rear is 6.5-8-10. I didnt want to have rear
Going around cam cover, or upward next to aircleaner where it will suck hot air
and be a leg burner. SPF did the pipe for my 124ci. Dyna SB pictured in my signature. Will be running Megaflow 110 heads, 640-cams @11.5:1, hpi tb and backing plate. Most likely 58mm.
Steve got them as close to equal as possible, within.my parameters. Muffler and collector are from
Burns, and yes it will be tuned with tts.
