There'* some company that has Corsa knock-off tips, forget who makes them, a local club member has them, the first thing I thought when I saw them, ohhh Corsa exhuast, I wanna hear it, but it was these knock off tips and was Flowmaster mufflers.
Be careful about knock-off tips, even if they look the same. They may be an inferior metallurgy.
That'* the thing I don't like about the flowmaster mufflers. They only come in aluminized coated finish.
If you plan on running year round, and I know you do, they will rust in a few years.
Good austenitic stainless steel, like Borla & Corsa use, use 304 or 316, will outlast the vehicle, look good after just a wiping and look brand new after a simple polish.
Some systems that claim stainless steel construction, like OEM brands, are an inferior martensitic 409 stainless. This will surface rust when exposed to salt and heat.
The Borla muffler, pipe and tip on my go anywhere anytime Jeep cost me $400. 5 years ago and looks shiny brand new with absolutely zero rust stains. It was a very good investment because before that, I was spending $200 every 2 years for an aluminized system that looked like crap after just one winter.
