Finally got my Mustang back!!!!!!a few questions.

[Oldschoolpony]

Alright, Well like I said before, we got 431 HP at 6500 and 382 torque@4500.
Under the hood, It has a K&N air filter, with the low bottum plate giving it about an inch of clearance from the chrome top to the carb. SO, I bought the K&N element top for more air. A plus for HP I hope. Next, and here' where I have a question.

The exhaust is 2.5"s and at one point, the pipes are like 4 inches apart. But, The dyno shops muffler guy did not install any crossover. My buddies shop said that they would install a 2.5" cross over (h pipe) for 25 dollars. An X pipe would be 10 times the cost, parts and labor.

Should I get the H? I have plenty of HP, but torque gains would be nice. Or should I buy a DR gas X pipe? by the way, this is a carbed card..barry grant 750 on a victor jr.

And after test driving it and almost wrecking!!!!!! I NEED TIRES.
I Have 15x7 drag lites all around, and the rear has 245/60/15 pirelli's. I want either the mickey thompsons or hoosiers drag (dot) tire, I know it will ahve to be a 9.5, But on an 88GT what height tire will work. a 28x 9.5 with minor fender mods or 26x 9.5????????????? The mods im talking about are the sheet metal lip o n the inside of the whell well getting ground down to protect side walls .
