I have a 92 RS 305 TBI. What headers will perform the best, install the easiest, and not rust for atleast a few years? I was looking at the edelbrock tes, slp,and dynomax. I was reading on the dynomax headers and they say they come jet hot coated. Also I dont want to have to bend anything for the stering. Let me know. Thanks

 

the dynomax one's are supposed to be pretty good. I had headmans on my 87, but the AIR stuff didn't line up right, so I just didn't use it. I don't really like the Edelbrock TES headers, if you don't get them powder coated they rust almost instantaneously.

 

The dynomax Y pipe is small. I REALLY doubt they're are coated. I think only the LT1 and LS1 ones are. Get SLPs if you can. Hookers or Edelbrocks if you can't.

The Dynomax shorties (the one made for our cars) are 1 1/2" primaries into a 2 1/2" collector. Then into two pipes, 2 1/2" on the y-pipe. Then into a single 2 1/4" pipe for the cat. Kinda defeats the purpose of headers. Better than stock manifolds, but not much. I dunno about the ones for the TPI motors though. They might be a little bigger.

If you go to their web site, you should find out more.
