Can anybody confirm this? (exhaust related)

I called Master Muffler and they said they do mandrel bends on custom exhaust systems. Has anybody went there and what kind of work do they do? I really doubt a 'chain company' such as that does mandrel bends but i could be wrong and their manager said that they could do it. Should I go with 2.25"?...I know at first I wasn't going to run any piping but my nitrous lets off flames after I release the button so I hate to leave my Muffler welded to the header and blowing on the gas tank....not good:flame: :burn:

well any muffler place can do mandrel bends....most of them just don't have the piping readily available unless they have a mandrel bender in house, they are really expensive so most don't. In order for most muffler shops to do the mandrel bent pipes they have to order it.
