i want to order the flowmaster 2 1/2 american thunder kit and a set of tri-y headers for my a code and i was wondering does a muffler shop have too weld up more pipe to mate the h-pipe or will it connect as it is ?

I did not have to add any pipe when I installed the full Flowmaster kit on my car. Actually installed the kit myself.
I am running different headers though. I am using the Hooker Competitons not tri-y's. I just had to bend the h-pipe to align up with the Hooker reducers, then weld them up. Actually I did have to trim one of the reducers just a little. (less than 1/4 of an inch) Like allcarfan stated, it will depend on your setup.
having a shop weld it up will make it last longer and elminate a lot of leak possibility... its usually pretty cheap too. I'd just get a shop to put it together for ya.
I'm running the Flowmaster American Thunder system on the Fastback, along with Hooker Competition Headers. I had to have a muffler shop make up some short connector pipes as I didn't want to modify the Flowmaster H-pipe.
