custom exhaust for $750/ should I?

Out of curiosity is it mandrel bent and what material does he use to make the exhaust? Is it 3 inch?

In my opinion, no. Corsa has already done the homework on this one. Virtually eliminating any droning in the passenger compartment, Corsa technology won't be in something that somebody cobbles up. Spend the money, get the Corsa, do it once, and do it right. pete the ex you know what
PS>>you'll also get the nicest looking 4" polished tips as well. Again, my opinion only (but supported by many here I'm sure)
