Header Advice
Car is a 1987 IROC Z with 350 TPI.
So after some research I decided to go with a set of hooker headers. But do i go with Shorty Headers as there seems to be some clearance issues with Long Tube headers?
I will be replacing the Y-Pipe as well. So do I go 3" to 2-1/4" is that correct?
I replaced from the CAT back last year and pretty sure it was a 3" Y-Pipe that was on the Car. Its in storage and I am away working so cant check exactly.
I can get a good price on a new set of MagnaFLow Headers and 2.5" Y-Pipe from my Buddy who drag races and has his own little Performance shop. Whats the verdict on MagnaFlow? Overall between Hooker and Magnaflow I am looking at $210 more for the Hooker Header and Y-Pipe over the Magna Flow.

Re: Header Advice
Typically try to get the matching brand header/y-pipe combination. I know a dougs y-pipe will go with hooker shorty headers. I'm not sure magnaflow will fit it perfect.

Re: Header Advice
Magnaflow makes thirdgen headers? Not finding anything on their website. You're not thinking Flowtechs? MF made a y-pipe, but last I looked it's discontinued and it was meant for stock manifolds anyway.
Which Hookers? The 2460s are OK, the Y-pipe they offer necks down to 2.5" after the Y. It can be cut where it necks down and weld a 3" extension on it to the cat. By all accounts the Dougs D901 is the same thing as the Hooker Y-pipe for $100 less.

Re: Header Advice
Yes the 2460s, and I asked him to price the Hooker Shorty Header and he gave me that price and came back and told me a price for magnaflow as well. Thanks for the info on the other y-Pipe!
I'll get him to check into it further!

Re: Header Advice
Both the dougs and hooker Y pipe really suck after the merger. They neck down horribly. I would cut off the area after they merge and weld on some 3" pipe

Re: Header Advice
2.5" to the merger then 3" all the way after that. Add in a resonator if you like. Finish off with the muffler of your choice.
