Need a new muffler on the old girl, cant find one to fit her. I have the banks sidewinder turbo and must be the exhaust system with it. Tried napa and another muffler shop,cant seem to come up with one that is like the old one. Do i have to buy this muffler from banks? Want to try and keep it pretty much the way it is without peicing a bunch of stuff togeather,but also dont want to spend a small fortune. How many of you are running without a muffler? Is it very loud without?
