H pipe question. . .
 

I want to convert my 2000 3.8L stang to dual exhaust. Does an H pipe require welding?

it better to have welding. Its a better seal

they sell H-pipes that just bolt up, and then you bolt up a GT catback to it. Its very easy and will probibly be cheaper then getting a shop to make you duals.

+1. Very popular with the 6er crowd in my town.

yeah i have a mac h and a mac dual exhaust set up and i love the sound... no i didnt weld it it just bolted right together, no leakage problems either
