Haven't ever messed with exhausts, but I'm wanting to get a cat-back for my ST as I think its what its missing the most. Seems like the most common solution is to cut the OEM cat-back as removing the thing whole requires removing the lower arms of the suspension on the LH side. My question is, if I cut the OEM cat-back and at some point wanted to reinstall it, is it possible to have a muffler shop weld the two pieces where i cut it or is that not possible? I'm assuming this isn't a big deal, however before I move forward with purchasing a cat-back I want to know for sure. I plan to keep my car for a long time and don't think I'll be regretting going cat-back at all (in fact I can't wait!) but wanted to know about this for sure beforehand.
