long tube headers?

cb18201 · Jun 9, 2004

3 quick questions: are they better for low end or high end torque? how hard would they be to put on a 88 gt? would my car be louder or quieter with them? (without cats) thanks

Do a search...real quick

1. im pretty sure its the short or equal length headers that are more for low end torque and long tubes that are more for top end power. Its ok becasue you can just put 3.73's or 4.10's in to balance it out. 2. They are always hard to put in, but now bassani has some headers taht i believe are long tubes and are individually assembled with the collector then slipped on at the end. 3. they are louder then other types of headers. Its a badass sound.

Long tubes should help power just about everywhere in the rev range - however, they should be noticeably stronger than shorties in bottom end torque. MM&FF just did a test comparing several shorties and long tubes and the 1 5/8" primary long tubes made almost 40 ft-lb. more torque at 3000 rpm than the shorties. That difference became less and less as the revs rose in their dyno test.

Installation is always a bit different on each car - long tubes are a challenge to install. You just have to decide if you want them or not. Many times motor mounts have to be disconnected and the engine jacked up, or the steering shaft removed and run between primary tubes - depends on the brand of header. Also, if your mounts are old, and the engine has sagged - sits lower in the bay, you may have some clearance issues. It's a good time to refresh the mounts - engine and tranny.

Volume is more a function of the rest of the exhaust system (cats, h/x pipe, muffler type, etc.), but most folks report that the annoying resonance around 2000 rpm is significantly reduced if not eliminated with long tubes. Do some research on the location of the O2 sensors. Installing long tubes usually results in having to move the O2 sensors further back in the exhaust stream, and that often causes some drivability issues for people.

does anyone know what brands of longtube headers that require the steering shaft to be removed?

i have flowtech long tubes and there were no problems except having to jack up the passenger side of the motor to get that side installed

I have mac longtubes that are hts coated. I love them. I think you actually have more room than equal length shorties. You will have to however remove one when swapping out clutches or if you need to completely take the bellhousing out. But that may just be the mac's. I still think they are the best.

did you have to disconnect your motor mount or jack up the engine at all to put them in?

rdksek844 · Jun 9, 2004

They were already in when I bought the car, but I did have to remove the driver side to swap out the clutch and as far as the driver side it was easier than working with shortie headers. I have never dealt with the passenger side but just looking at my car it doesnt look that bad. Starter clearence is less with long tubes, but I was still able to access the starter with the right extensions when I swapped out my clutch.

Oh, I just noticed that you have a 94. I am refering to a 93 fox, so there may be some clearence issues with a 94 that are not existant on a fox.

Check out my install guide here. Fox LT install

They gave me power all through the rev range. The install isn't really that hard. It's 1000% worth it. Just do your homework first.

Nice Job!

Nice job on the documentation Matt. How's that header coating holding up?

Better for power everywhere, but especially low end TQ.

Depends on which brand you go with. Hooker Super Comps do not require engine jacking, steering shaft removal, and the tranny/clutch can be swapped with them in place.

Different sound all together.
LT's have a deeper tone, less harsh, say good bye to drone... plenty loud, but not a piercing type of noise... I like to say shorties have a hysterical sound to them, and long tubes have an authoritive sound.

well there not going on my 94, there going on my 88 im getting
