If I get non-shorty headers how will I connect my exhaust into a single inlet. I cannot use my stock y-pipe so where do I get a collector for our type of cars. I decided on the flowtech 1-1/2 full length headers.

You'll have to have a custom Y pipe made at a shop, from my knowledge.

 

or, if you can, run duals. check out my post called dual 3" dumps

 

There has been talk in the past of a Mufflex y-pipe made for long-tube headers. I've never seen one personally, and don't know where you would go to find one. Plus, it is made for 3" collectors (as I recall), and you're looking at 2-1/2" collectors.

Also, can't say I'm too impressed with your choice of headers. Flowtech is a division of Holley, and they do okay work, but that brand is aimed more at the low-end market than the true performance crowd. A set of Hooker shorties with their excellant y-pipe would most likely out-perform Flowtech 1-1/2" primary long-tubes. No ground clearance, routing, or emissions issues, either.

 

I was thinking the same.

 

i didnt even know flowtech made long tubes that fit a 3rd gen chassis. i would check and make sure they fit a 3rd gen f-body. flowtech shorty headers are a good value for the money, but they do only have 1.5" primaries. although, they still allowed my modded 350 to run 13.87 with no tuning, no gear, and absolutely no traction. that said i am getting hedman long tubes cause i found a place to get them cheap and they will hook right up into my dual exhaust. if you want long tubes the hedmans are a good value and they have 1 5/8 primaries and 3" collectors.

You're absolutely right. I saw the "**" by the other 3rd gen Z28 p/n's, which said shortie, but that's what Footnote 54 is, too (looks like 11102FLT is missing one "*").

So, they aren't long tubes.

 

I believe Hooker & Hedman are the only ones making LT's for 3rd gens. Got a set of 2210-1 Hookers & a Mufflex Y-pipe here next to me om the floor. Any questions ?

 

Ricktpi: Is that Y pipe for the ones who want to make the exaust goes in the middle with the driveshaft. or does it goes to the stock location (under the passenger seat, where the cat should be, well mine is a single cat desing)

Yanick

 

With the longtubes you can't have the cat in the stock location, the header collectors come back farther past that area. The Mufflex y-pipe exits on the pass side of the driveline tunnel about 18" behind the trans tailshaft.

 

yea the mufflex y pipe is 250bucks give or take and is used with the hooker supercomp long tube headers which the y pipe was designed for. i plan on gettin it soon and the reducer so i can put it bakc into my hooker catback.

 

Yeah I was shocked at the cost. It is a damn y pipe. I was hoping someone else had a cheap fab idea I am afraid I dont want to be the first. I will have to go with shorties or get really ambitious.
