My OEM mufflers were beginning to rust out and seep at the seams. It ends up in the ear of the beholder, but had I to do it again AND had one of my tailpipes NOT been crushed and jacked by the PO, I would have just gone to a local muffler shop, eyeballed their appropriate selection and had them weld something in. Less hassle, less money and negligible performance delta, additionally the factory pipes were of sturdier stuff than what I replaced them with. ((I now have SLP Loudmouth II cat backs that are good enough, but drone right around 2000rpm and are loud enough inside the car to cause me to lift a little when I see an LEO)).
Underestimate me, that will be fun.
