NEW QUESTION BELOW***

 

You'll have to grind the A arms for clearance with the 68460s. You don't need to replace the starter if you're using a 153 tooth flywheel.

Long tubes aren't worth the trouble for a street car.

 

why do you say "trouble"? if i only need to grind a little a arm off and install, then they should be easy? stick em in there, bolt it up and make a quick Y pipe to fit the stock catback, it seems real simple.... imean ive heard of people needing to lift the motor and stuff i dont want anything to do with that... but that stupid shorty with Y pipe from hooker is 450, way too much IMO for a set of shortys...

 

The fitment issues aren't really the problem, it's the hassle of building the rest of the system, and giving up the ground clearance.

I've got 68460s on my 84. I wouldn't put long tubes on another thirdgen without some compelling reason.

 

whats the best shorty y pipe combo for direct bolt on and clearence?

 

here is what i did with mine. this link shows all my part numbers and cost me around $350. those extensions are also available in smaller diameters. https://www.thirdgen.org/forums/exha...to-single.html

 

im not worried about ground clearance, lol i DD a lowered 1990 honda crx and a cutout that sits about 2" from the ground... but yea i agree it may be a little hassle...

 

long tubes are worthless on the street. shorties are your best bet, look around CL, i found a 500$ edelbrock header setup that i paid $150 for, took me about an hour to install in my driveway and it was worth it

 

yea i agree but when you guys keep saying their worthless "on the street" what are you referring to? just the ground clearance issues or that since its a street car i shouldnt get too excited about trying to pull a little more power with something complicated?


thanks,

matt

 

Both

 

im running those same hedman headers for two years.... you have to grind away a little of the a-arm and frame for them to not vibrate on your car... they are a direct bolt in but you will be hearing this constant vibration if you dont cut those areas.... good headers tho..... i seldem scrap anything... i just avoid all speedbumps....

 

IMHO the long tubes will not make much if any more horsepower than a set of good shoties such as Dyno Don's. The long tubes will make more torque in the lower rpms. Most of us with higher powered cars are trying to kill off the torque as we have to much anyways for traction.

 

okay well lets say i did go with the longtubes... where do they stop under the car?? and, where do you fab the drivers side, will i have enough room to make a 90 bend over to the stock location? pics if you guys got em, thanks


matt

 

when we say that it means theyre more work than theyre worth, a good set of shorties to a y pipe are sufficient for a some decent power, those longtubes will be your worst nightmare installing and youll be pissed when you smack them on a speedbum or something and then kink the pipe, shorties with a y are good enough

 

68460s end inside the frame rails pointing more or less straight back, about even with the back of the block. Stock exhaust routing isn't an option.

 

ah damn, okay, well looks like i need to find a nice set of shortys then...

ohhhkay, quick one here... i was debating everything with this exhaust, didnt even think about it... for now, i can just buy the set of hooker shorty headers minus the Y pipe and itll hook right up to my stock Y pipe right?? i need to get stickers on this thing and get it out of my parents driveway, theyve been bugging me about it! lemme know if i can do this, thanks


matt

 

no. it will not match your stock y.

 

if its just temporary, can't you just get a set of manifolds at a salvage yard?

 

i could, its just like 6 feet of snow here lol


i have manifolds off of a 400 laying around, think theyll work??

 

no. not likely. you might be able to get them on but might not be able to get a pipe to hook up.

 

okay well i called up summit to see what they had for me.. theyve got a set of flowtech headers with a Y pipe for 289$$$

will these be legit??

 

Well they're cheap and they'll work. The primaries are kind of small, and the Y pipe design isn't too great. Some people have reported fitment issues.

 

ha yea but for right now anythings better than stock... okay i guess ill buy these and throw them on, i just need to get a car to drive here

 

Why not just get these.They`re a good header for the price and much better than the flowtech.these could support most mods you will through at them in the future.

ha yea but theyre longtubes, then custom exhaust right??

 

Those hedmans are shorties.

 

well what Y pipe will i use with them then??

 

This http://www.summitracing.com/parts/HED-17478/ Jegs prices are a little cheaper. Or have a shop make one.

 

good call, 130+150 is around 280, same as other price but liked much better.. looks good guys thanks a lot

 

IMO, if you've got a T5 and some fabrication experience or a T56 and you can make a custom xmember, I wouldnt think twice about doing long tubes. I've got very good clearance with mine.

But if you've got a 700r4... I wouldnt do it.

 

yep 700r4 87 gta, not too much room lol
