I just cancelled my order from cj pony parts. It was my order of longtube headers. And its been 5 weeks and they didnt even get a tracking number for it. So i called mac up and the guy tells me theres a tremendous gain of hp and sacrifice of tq at the hole when you run your car with long tube headers and with shorty headers you get mid range and low end power and some top end. Then he told me with my set up of divorcrd pipes im loosing hp.

True or false?

If you dont mind some lost low end torque, plus LT's are way better sounding than shorties, so I've heard and red. But 4:10's will set that lost LT torque up right away ÷}

You will never notice the loss of power down low. It's so insignificant it's not funny

Im going to have my exhaust shop put a pipe across to form the h pipe and see how that works. I dont want all the trouble with longtubes its just more issues right? So im looking at the ceramic bbk shorties how are those?

Shorties are always a waste of money even if its for a repair, grab some 94-98 factory manifolds, they actually came with shortie headers, cheap and just as good as $350 shorties

You can use them but you'll have two dead o2 sensors sticking out of them which is ugly and you have to open up the holes on the flanges cuz the bolts on those headers wont't fit plus the time it takes to pull them out of another stang.

I still dont understand how back pressure gains torque?

Everyone tells me how, if you go duals you will lose torque but yet no one gives me a good explanation or proof that it does. I dont see how back pressure is good for any gas motor

I would go dual it evens the pressure out

From what I've always understood is the v6 is an even firing motor so a crossover mid pipe isn't necessary to even out the pulses but I don't believe it would be a bad idea to use one. Do make sure that if you go dual that you size the pipe right because back pressure is not good. An exhaust that is too large will cause back pressure as well as too small of an exhaust.

You may lose some tq but it removes the heat faster,,and allows your engine to breathe...Theres someone on here that posted a good article about back pressure,,theres alot opoinions about ,,look back on some previous links on here

Ok, i did a research paper on back pressure so heres the stripped down explanation. You want as big as a pipe as you can get and as free breahing as you can make it UNTIL it become s big that air no loner consistently moves through it. If your pipe gets to big or free breathing at low rpm's the air is no longer moving quickly because it is not forced to and it breathes less well then with a smaller pipe. Theres a great article explaning it i will try to find and post!

Here you guys go, its not the one i was looking for but it explains it crrectly and more detailed with the pulses of the engine. i'm tired of back pressure talk so please read and spread!
