i need a new exhaust system for my 1990 Mustang V8 5.0 automatic, but i really dont know what to look for, i need somthing loud, but can pass state inspections {i live in PA if that helps} and do u have to have correct measurements for getting headers to match up with H or X pipes? any one have suggestinons that would be good for me

 

yeah same here! i have a 1992 mustang GT

i want something loud, my caousin has a 1991 camaro z28 and he use to have Duel Flowmasters, and now he has 1 pipe, he saids it is louder, but i am not sure?

So would it be louder for me to get Flowmasters or just go one pipe? or what would be best to get to have a loud exhaust, If i went straight pipes would that mess up your car? or have any bad effect to my car?

wouldn't that work?

 

is this Pypes x-pipe w/ their mini cats? I was gona get one of these but found out the O2 sensors don't reach. You can cut the clip so the front sensors can connect, but unless u buy longer O2 sensors (rather expensive- maybe 300 or so) orgetextensions (85 or so, not sure how efficient they are)the back 2 sensors won't connect. Thus, the check engine light comes on and the car won't pass inspection. Otherwise i've heard the hi flow cats are great, and not too mention much louder than the stock cats. And just throw some flowmaster 40's, super 40's, or super 44's and the car will be LOUD, yet not high pitched.
