I found these and was wondering if anyone has any experience with the fit and such on them?

Re: How do you feel about flowtech's????
Anyone know a good cheap shorty or longtube that works with a t5 and y pipe, I would buy headmans but no one makes a y pipe and they need mods to the collector.

Re: How do you feel about flowtech's????
Then no, there are no off-the-shelf Y pipes for Hedman long-tubes. Stick with the shortys anyway, there's no advantage to long-tubes on a street car that makes up for the disadvantages.

If built right there are no disadvantages.. Plus the long tubes are cheaper then the shortys. Longtubes will make more power... I prefer longtube headers always.

Re: How do you feel about flowtech's????
Come back and tell us there are no disadvantages after you've put a set on a thirdgen, especially one with an automatic.
Even if you built it right and managed to lose no ground clearance (next to impossible with an automatic), the fabrication hassle to do so is a disadvantage. The power gains, if any, aren't all that substantial and don't make up for it. Long-tubes will get you bragging rights, but that's about it.

What are the best bang for the buck shorty headers? Something cheap, flows good, and has a good y pipe with good clearance then?

Re: How do you feel about flowtech's????
Hooker 2210s are long-tubes and clear the slave cylinder just fine.
The problem with long-tubes isn't even the header, it's the rest of the exhaust system. The collectors dump up between the frame rails, so you have to run tubing under the frame rails to get it to the back of the car. There aren't many ways to do this without losing ground clearance. With a manual transmission, you can run the pipes back inside the rails on either side of the trans and build a new transmission crossmember to clear the pipes and keep the loss to a minimum. The body of an automatic is too wide for this. There's no room between the trans and the frame, so the only way to do it would be to cut up the frame rails.

Re: How do you feel about flowtech's????
Who knows the part numner of the long tube swept headers that run in front of the oil pand and the pass side sweeps along the starter, the 2 combined run just like the stock system, along the passenger side. Was it a hooker or hedman header? I swear it was a hooker but can't seem to find them. They were full length, 3" collectors, 1-5/8 primaries.

I can't find them right now either. I thought they were only 1 1/2" primaries though.

Re: How do you feel about flowtech's????
I just took in a set of Flowtech shorties in on trade. Thinking of using them on my 305 when I do the V8 swap. What Y-pipe do you use with these?

Re: How do you feel about flowtech's????
im currently running flowtech shortys on my 355 T-5 with their matching y-pipe which flows through 2 inline chambered mufflers out a single exit (infont of the pass. tire), dual tip pipe and i must say, i have a ton of low end torque, not to mention, the car has a sound coming out of it that scares even the newer generation muscle cars. in fact, id give alot of credit to the exhaust for my light to light win against an 07 Mustang GT a few months back. just my 2 cents.

Re: How do you feel about flowtech's????
Well I've been running these with the Y pipe for 2 years now. I'm Running a 350/auto combo and they do make a decent gain in power over Stock. But having said that the fitment is poor on the Y section. Plus its not really a Y, the passenger side just T's in with the Driver side, so flow isnt really all that great. Mine came Painted black as did the Y and both are very rusty. It didnt take 6 months for the paint to bake off of both, so i would suggest some Coating or Header paint before install. For the price though overall they are good.....not great but good.

Re: How do you feel about flowtech's????
I like the cleaner look of the hedman 68470's I have. they fit and sound good. I just dont like the way the flowtechs have the one tube bend up and over.

Re: How do you feel about flowtech's????
I've got them with the matching Y-pipe. Noticed a pretty big difference over stock. I had to splice out a section of the Y-pipe right below the center of the engine cause it was too wide. Had to have an exhaust shop weld it back together. Came with black paint, that I removed with paint stripper and re coated with high temp paint. Been about 6 months and no rust on them yet...

Re: How do you feel about flowtech's????
You're gonna wanna eyeball the inside of the passenger side Ypipe flange. Mine was really poorly cut, big ol' overhang of metal where they just punched a 2" opening through the pipe and welded the flange on afterward. It could really use some cleaning up.

Re: How do you feel about flowtech's????
I used to have those headers and they were pretty good. For $100 I had a muffler shop fab the y-pipe, no need to fight with the pre-made y. The best thing about these headers is the ability to change all the spark plugs from the top. The only plug you will have a problem with is #6, but its not too bad lol.

Re: How do you feel about flowtech's????
Haven't used a set of flowtechs in a thirdgen but I have installed them in several other cars. Fit has actually been surprisingly good, but material is thinner and their paint quality is pretty much awful.
