i have a friend that has access to a mandrel bender and 2.5" stainless steel.... if i were to have him weld me a custom system up and have him weld the stock muffler back on would i see many gains.... i have a WSP Ypipe and a stock starting to fail cat. i like the sound of stock so if i can still see gains with teh stock muffler i would like to do that, but if that will still restrict the flow, what are some good mellow (close to stock) sounding mufflers??

Get a fifth gen muffler. You may see some gains from it. If you're going through all of that get a better muffler.

well im going mostly for MPG... espescially since winter is coming up and my last tanke was 14mpg and im used to 22-23. i just want a few extra mpg and my friend wont chage me for the steel and ill just give him like $100 for welding it all up

think he could make some regular steel 2.5 inch mandrel bends (180 degrees) and sell them for cheap?

it sounds like you should be buying a new o2 sensor and tuning up your car instead of replacing some pipe...
