Dyno Don Headers & Y-pipe
Headers were used on my 86 LB9 w/aluminum L98 heads. No need for them with the ls1 going in so they are for sale. Will throw in locking header bolts and gaskets, but you'd be better off buying new ones. Will also come semi new o2 sensor, and band clamps.
Headers have no air tubes, are 1 3/4", raised to work with d-ports and all aftermarket heads with raised exhaust ports.
SOLD

Re: Dyno Don Headers & Y-pipe
So are all Dyno Dons headers have 2.5in. collectors? I thought they were 3in. from the collector to the end of the y-pipe.

Re: Dyno Don Headers & Y-pipe
Do you still have these headers? I am interested in them if they will work with a 3rd gen LT1 swap. How many O2 locations? I need one in both sides.
I cant see the pictures right now since I am at work.
