Header interchangeability - y pipe
Header interchangeability - y pipe
Hi,
I'm planning a top-end rebuild on my 305 soon. I have all the parts ready, I just have to start wrenching.
I'd like to get a set of headers for the car, and I know which types I'm considering.
BUT, I only really have the money for an uncoated set of flowtech's (1 1/2" primaries), and a Hooker y-pipe.
Someday, I'll be going to a 350, and at that time I'd like to go to a 1 5/8" coated header. Will I still be able to use the same y-pipe, if I use another shorty design?
Will I be able to use the little Flowtech headers with the Hooker y-pipe?

I just called holley and they won't sell me thier y-pipe. Tas was able to do so after he bent his but I could not convince anyone to sell me one. Anyways, I ordered a set a coated flowtechs that come with a y-pipe and an O2 bung for like $395. That is a pretty good deal if you ask me. Anyways flowtech makes a y-pipe for that header. The header is 11102 and the y-pipe is 11102y.
In jegs headers are 387-11102 and y-pipe is 387-11102y. $200 total for both. Not bad.

davehamilton - That's a good question. The reason that I didn't want to buy the 1 5/8" headers right now, is because I don't have the money to coat them, and I'd hate to rot them just for my 305. The 1 1/2" are a little cheaper, and I'll basically treat these headers as throw-aways (don't have to spend them money getting them coated), as I won't put them on my 350.
Which brings me to my next question, can you take USED headers, and get them coated? If I sprung for the 1 5/8" headers right now, and left them uncoated on the 305 (with some hi-temp paint), would I be able to get them coated a few years down the line?
I will take a look at those part #', ShiftyCapone, thanks.

You can get used headers coated. Take a look at www.jet-hot.com and they have a pic right on the front page of a rusty header and then a treated one. They have to sandblast all headers anyways so it doesn't matter if they have rust on them.

get a couple cans of VHT flameproof 1500* paint and strip the shipping paint and spray down with the VHT. it works pretty good and should prevent rust for a while. what brand of headers are you considereing buying? also if your headers is extremely rusted when you give it to jethot or whoever then they can still coat it but the coating may have some pot holes in it(not perfectly smooth). like i said though the paint should prevent it for awhile.
smashed Y pipe update:
when it rains it pours. The exaust guy said for him to make a Y it would be like $150. Hooker wants $160. I think I'm just gonna put the stock crap back and sell what's left of the headers and 3" cat.

I'm undecided as to whether I should get the Hedman or Hooker setups.
Does either one have a y-pipe that is 3"?
Why did you pick the Hedman one, Brody?
Tas, are you selling your Hooker headers? If so, which part # are they, and what's your asking price?

I sent Tas a PM respectfully declining his offer for the headers, because they're not quite the part I was looking for.
If anybody else needs them, feel free to shoot him an offer!
Brody, thanks a lot for the pics. That sounds like a good way to get a 3" y-pipe, and save a little $$$.
I will try that.
Thanks a lot, guys!
