TTI Shorty Headers VS Doug's Long tube headers??

Agree totally if you are installing them on an automatic equipped car. They are well tucked up to the subframe. However, when installed on a 4-speed car its a different story with ground clearance, especially the driver side.
Same header, less ground clearance in a manual trans car vs an automatic.

Bullshit
Shortys will not perform as well as long tubes in higher rpms so if your major use is street driving , not racing and ground clearance is an issue for you , the shorties win hands down on a street driven car.

They, shorty headers, provide less torque. That is essentially what a street car is looking for.

I can only reference my 68 Cuda, not other cars but I've had stock manifolds, long tube headers and now, shorties. My car runs mid 11's which I consider great for my setup and I can drive it anywhere without having to worry about scraping collectors. Also agree that TTi as a brand are excellent. I spoke in length with the people there before getting my full system from them and followed their recommendations.
As a side note, ever see the " Exhaust manifolds " on a 880 hp Demon??

Look familiar??

Comparing a modern car to old cars is smudging the whole thread as comparing todays tech to yesteryears cars is not an apple to Apple comparison. Your moving the goal post and blurring the issues.

This is bullshit.

Next you’ll being in the FAST guys running 11’s with exhaust manifolds as proof that exhaust manifolds can perform when anyone that knows a little something knows that the engine would seriously wake up with headers.

You have selectively choose items as to dispel other things as myth or bad. You’re blueing the facts and championing lies. Sorry to see you hate facts. Your post is loaded with them and I can now label you as a lier and/or a know nothing idiot.

Do not speak to me.
