Need 1990 GT exhaust help
 

New to Mustangs and need someone with experience. I need to replace the exhaust on my 1990 GT. The way I understand it the car came with factory headers but from what I am finding the studs break? Am I right about that?
Would like to replace with new headers and a complete exhaust. Has anyone done this and what did you use for the headers and the complete exhaust. Any help would be appreciated.
Thanks

long tubes will make most power and that requires a new "shorty" mid pipe for long tubes then whatever catback suites you. YOu dont need 3" unless you are pushing lots of power think 500+.

thanks for the info
 

I appreciate the help

my car already had exhaust on it when i bought it. shortie heads will do you fine till 450 hp. but long tubes will give you an extra 10-15 ft lbs of torque... at least. unless your on a super budget, i would pick up a set of used long tubes with mid pipe, then use header paint/header wrap on them. i have bare shorties and the engine bay gets really warm and it sucks pulling that into the motor. after that its personal preferance. 2.5" will be plenty. mine was bent up by an exhaust shop with flows. i think the summer branded cat back is less then $200 shipped. you can do the whole exhaust for less then $600 w/ long tubes if you take your time and pick the right parts off the internet.

anything else just ask man!

Thanks
 

I appreciate the information sounds like the way to go with the long tubes.

You just need to watch which long tubes you get. Some of them do leak at the connection. I had a set and they leaked so I put shorties back on it and did a complete exhaust with off road H-pipe.
