The hooker and summit sites. Plus my mechanic who is going to install them for me. They are recommending HOK-16767HKR with HOK-2460-2HKR .

2460s are made out of heavier gauge stainless steel, and don't normally come with AIR tubes. 2055s should fit your car fine if you have a 3" single cat.

Those are Dyno Don's custom headers. Those are the only ones that work with dual cats. The other companies stopped making dual-cat headers.

If your '91 is single cat, it'll be the small 2-1/4" one. The 2055HKR pipe to the cat is 3". '86-'90 TPI single cat application cat & cat-back will fit the chassis just fine (might have to alter a hanger or two).

Not completely true. Hedman 68491, $365.95 from Summit (the picture and application button info are screwed up on summitracing.com).

I have a single cat system with the Borla Cat back exhaust. I have no problem changing the cat to handle the 3".
