alright guys well after starting up like 5 threads about exhaust systems...lol...i found a dude that was parting out a mach1 and made a deal for the cat back, which was stock. what all would i need to weld this on to my system if i cut the y pipe after the cats?

as in extra tubing to make it fit ect

 

Hmm, i would go for it. IDK the diameter of the tubing, I'd say its alot larger than a V6's. I have just a flowmaster in place of my muffler and im very happy. If you do go for the exhaust. use turndowns. Those open tips may not sound as well. BUT its your preference.

 

im pretty sure the tubing is 2.25 just like the v6 and the gt's...but i dont knowfor certain. i'll probably look at it once they guy gets it to me and then i'll be better able to tell what i need

 

yep stock exhaust on it is 2 1/4" so if you want true duals you just need some extra pipe to connect the cut Y to the catback.
