Looking to purchase one of these MBRP cool duals 4" cat back kits. First who has the best price and would you buy alluminized or stainless? Butch.

Same here, stainless if you plan on keeping the truck for a while.

I got my MBRP 4" cat back from Nate at Performance Truck Products. I recomend 409 stainless, its equal to stock. Mine sounds great, not too loud, but a much deeper tone

butch32,

It depends on where you live, aluminized is OK for the south, but if you are in an area that has salt and mag chloride in the winter the aluminized will start to corrode anywhere it is welded on on or has been cut as the aluminized coating is gone from those areas etc. The stock material is 409, so lots of folks want to stay at that quality level as a minimum, everybody is different so you have to make that choice though. Plus it depends on how long you intend to keep the truck. If you have any questions please call us we are experienced at answering the questions that ou asked about and will be glad to help you on them or a system.
