Hey guys. I recently purchased a dual walled mbrt5110 exhaust tip for my 2002 mazda protege lx. The inlet size (3.5") is fine but im having trouble with the length of the exhaust tip. It's 10" but its too long. I took it to my mechanic and he said he cant cut it since its dual walled. I need an exhaust tip that has a 3.5" inlet and is 6" long in length. Can someone help me? Do you know if it can be cut?? Or is it better to look for a new one? Because i cant find a 6" long exhaust tip with a 3.5" inlet. Please help!!
