Ok first question, how are these mufflers for my current exhast setup:
BBK 1 3/4" Ceramic Coated LT Headers
BBK 2.5" Shorty H with Hi Flow Cats

currently using some unknown flowmaster muffler and dislike the sound and im sure theyre restricting some performance too...

I emailed one of the Spintech reps and heres what they suggested.

I wanted to get your input on in first tho

As for the Second Question:

Will these tires fit on my 92 stang or are they too wide?
Theyre Nitto NT555 285/40/17's
Got a pair FREE at the drags last night, was great
and what size rim are they going to go on? Obviously 17's but what width?
17x?

I currently have 245/45/17's on all four

 

whether they fit or not will depend on the backspacing on the wheels and fenderwell clearance. wheel width should be no less than 1-2" smaller than tire tread width.
and how the hell did you get so lucky as to win a pair of tires?????? LOL

 

i really have no idea, was VERY surprised myself.
He just said he was looking to get rid of some tires
theyve still got a decent amount of meat on em too
