They need to be brought back into production because they have bigger tubing and Ypipe than SLPs
nah dude there not bigger tubing than slps the holes on the flanges where they join to the y pipe on both sides are just bigger on the accels, the pipe is expanded to fill up the larger hole on the flange its expanded at just that area about a 1/4 inch deep looking at both sets side by side it would appear that the accels are bigger though
you can actually see this expanded area im talking about in bigblocks post where he has them hanging up ceramic coated
the rest of the tubes are exactly the same i own both sets and just checked, some primarys check out at 1-5/8 and some at 1-1/2 on both sets the y pipe tubing is also exactly the same when comparing the same area
the slps are still superior b/c of the stainless steel
I'm wondering if Accel also had 2 sized headers like SLP?
I do have pictures of a accel(?) tri-y dual cat Y pipe with 2.5" tubes. Maybe 2 sizes there too?
I saw a set on craigs list. They had the air tubes removed and were very rusty.
I contacted him and he said he just sold them.
Two guys got into a bidding war and he got $800 for them.

I finally got these off my car and they are 1 5/8"
Had some one contact me last month and his accel headers are 1.75.. Also am looking at a set that are 1.75 header and 2.5" Ypipe
I wish I could find a old accel catalog, it would go nice with my new cabinet !!!
I will take a better measurement with my dial caliper today, but I did take a quick measurement with a tape measurement and got 1-3/4". Let me make sure.
Damn, I'm jealous on that Accel cabinet, there was/is a Accel book rack in eBay, might make a nice pair! Has anybody ever scaned any of the Lingenfelter catalogs?
Bring this up from the dead looking for collector gaskets for these? IIRC thought some import used same gasket.
I picked up a set of these but for a G-body - I never know SLP made G-body headers
if anyone has a G-body with SBC they are available PM me thay are in great condition
