Exhaust Flanges I am looking for a place that makes flanges to weld to 2.5" tubing that bolts to the headers. I have JBA short headers that use a 3 bolt pattern on a LQ9 engine in my 1978 trans am. These flanges would bolt to the exit side of the header and get welded to the 2.5" exhaust tubing that goes to the mufflers. I realize most people have probably used longtube headers with a standard collector. These headers fit without any modifications. What are people doing that are running with the stock manifolds?

I was going to use JBA short headers from a 2000 camaro. I tried the LQ9 manifolds and the 06 LS2 GTO manifolds. The truck manifolds kiscked out too wide and the LS2 manifolds were close to working except the bolt pattern on the passenger side was orientated to the outside. I found a set of SLP headers last night I am going to try. They look like they will fit if I move the brace behind the control arm bracket. If these work I will sell the JBA headers for $200. I liked these because they were stainless. I found a place to get the flanges last night for $20 delivered.
