I plan on purchasing the Hooker Shorty Headers that come with the y-pipe for our cars. I have a few questions though:

1. Will it bolt up to any 3" Cat?

2. Does it include all of the hardware and gaskets?

3. How loud will it be with the headers, a high flow cat, and the Hooker cat back?

Thanks.

Also, did you guys like the results of these headers? How's the low end power? Thanks.

 

If you're talking about their 2055 headers, then I can answer your questions.

1) The Y-pipe will only fit the '86-92 3" single-cats with the slip-fit connection at the front.

2) They included bolts and gaskets, but I used Stage 8 bolts and copper SCE gaskets. No leaks so far (once I put the gaskets in the right way).

3) It'll be sound really good with that combination. I have a Dynomax Super Turbo cat-back and it was somewhat loud with a gutted cat and sounded great. With a Random Tech cat, it's a little quieter (doesn't wake up my daughter now when I leave for work) but still sounds wonderful.

AFA results, I dropped a couple tenths and picked up 1-2 mph in the 1/4 mile. I can definitely feel the increased torque throughout the rev-band, at least from 2000 rpm and up. Spinning my tires became even easier.

Thanks for the info. I have an 84 Camaro, but I am putting in a 350 TPI and a new exhaust system. The headers will fit, even though it's an 84, right? (I ask because I assume that the years they are referring to are just for the size of the cat, but I'm not sure). Will they fit on a 3" Dynomax Super Converter? I don't know if they are slip fit. What other choices do I have for cats? I can't find any 3" cats at Summit or Jeg's besides the Dynomax. Thanks.

 

Summit also carries Catco. They don't list it specificly in the catalog, but with the p/n, you can find it on the web site.

JCW's high-flow cats are Catco, also.

These Hooker headers (#2055) will fit your '84, but you'll need to replace the cat with a 3" slip-fit model (like one from Random Tech or any other model for '86-92 TPI single-cat F-bodies). I think the connection between the back of the cat and the intermediate pipe (cat-back) is different too, so you'll either need to buy the right cat-back exhaust or have an exhaust shop modify your existing pipe.
