Sorry for the stupid questions:
My mate drove his thundercat into a fence & wrote it off

The exhaust is undamaged and he says I can have it.
The question is; can I use this exhaust on an SV?
If I can (pun not intended) can I fit this easily?
How do I attach it to the existing pipework?

Welding or is there some handy bolt section?
Will it look like an abortion if I don't like it and go back to stock?
Searched for the info on here and other places but nothing seems to answer my noob questions.
