HI, I seen a few on ebay but dont know if they are good or not. I have been told to steer away from ceramic cats and go for steel/stainless maybe Metallic ? after your thoughts and reasonable prices for a good one?

Not sure which one, but I got one of the ebay ones, there's a few different ones. Was about $200, metal core, good build quality. There's pics of it in my thread. Fitted it with Genie headers and 2-1/2" system, no resonator. Sounds good on the car. Was taken off the road not long after I fitted it all so haven't had it tuned yet to see if it's made any great difference. Have a dyno sheet from before the changeover, so will compare it when I eventually get around to it.

Mine isn't a name brand. It's from Scott's Rods, and the ebay user name is exhaustqueen. Mine was made for a VL so had the flanges fitted, less mucking around for me and fits perfectly.

Can't remember, and can't access the old auction to check, not sure if I got a 100 or 200. Car certainly went better after the system was fitted anyway.
