Part #11108FLT with long oval exhaust ports. I tried them out. They fit with lots of clearance.
Only issue is they come with 2.25" collector extensions. The collectors are 2.5". So I found some that were 2.5" to 2.5" on Ebay. Another $30.00.
I'm going to put 2.5" exhaust all the way through.
That's good it cleared everything very well. Their on Flowtechheaders.com. They didn't have the 2.5 to 2.5 extensions.
More yet to do.
