LT headers, help me TCG

[Shibby50]

Well I've been looking into Longtubes for the GT for a while now and all it's making me do is

MAC is about the only reputable brand that makes them for a GT with an auto trans, and the flanges/bolt up points are at different lengths so it also looks like I'd need to swap out my bassani band-clamp mid pipe for the MAC matched H-pipe.

If I do that though, my cat-back is band-clamped to the bassani mid-pipe. And the MAC pipe that would be replacing it has flanges to the cat-back so I would have to either change the cat-back or have a shop cut and weld on some flanges.

Anyone have any alternatives? I'm almost looking to just get shorty headers because the bassani mid-pipe is already 2.5in. going up to the manifolds, but they shorty's are only 50$ cheaper than the LT's and I don't know if they will net the same gains.

That is also another thing that's slowing down my purchasing process. Anyone on here done it? That's too many major moving parts for me to feel secure doing myself.

Dunno about the Mustang, only did it on the LS1 and that was more of a bitch than I was expecting.

Mustang headers are 100x the bitch that LS1 headers are...

The old style SLP headers going on the auto camaro were terrible. Had to drop the motor a few inches to fit the fuckers in there. I'd imagine teh Mustang being worse, looks more cramped.

The only way I'm hearing to make it easy to install is to put the car on a lift/up in the air a bit, support the motor with a cherry-picker and drop the subframe. This does not put a smile on my face..

sounds about right to me. the one time I had a shot at doing it, greasy had bought a set of shortys and once we looked at how much of a PITA it was going to be, he ended up just selling the headers and leaving the stock manifolds...

hmmmm not sure how much harder it is to install on an auto f-body, but my pacesetter LT's weren't to bad on the T/A. and i did it in the driveway with just a jack and jack stands

Yea, TA vs Mustang header install are two completely different animals unfortunately.

I'll look for the thread about it, but I thought I read that the gain from shorties is not worth the time of swapping out headers. It was either LT's or stock headers. I'll look to see if I can find the thread.

Not even worth mentioning an LS1 install for comparative purposes.

All you have to do is unbolt your air box/ battery etc. Misc shit up top, you drop your k-frame and sag your trans mount and bam they slide in like butta. Of course i'm doing this all on a lift. It's not an easy job took me by surprise the first time I did them. I put MAC LT's on 2 m00tangs now.
