TTI Exhaust Systems

Cool.......... I had a hunch that the "H" scheme and the 2.5" pipe would be okay.

Do you guys think an "average" mechanically minded hobbyist equipped with an adequate array of tools (such as myself) should try to install the exhaust system (I don't have a lift - I'd be using jack stands) or should I let the pros have at it?

And should I have flanges welded to the unflanged Spitfires - or will a "sleeve & clamp" type of apparatus work?
