I was wondering the same thing last night. It looks very similar to the SLP stuff. I'm not in the market, I just noticed they looked a lot alike and was wondering if the sound is at all different.
That is one hell of a deal because it's 304 Stainless Steel and 2.5 in diameter!
And they come with 3.5" ROLLED tips that are very nice!
Buy it, put it on, drive around for a while, and if you don't like the sound, sell those mufflers on ebay for like $100. THen go buy two mufflers of your choice (magnaflow, borla, flowmaster, etc) and put it in. That way, you're still way ahead of the curb (price wise), and still have a very nice SS 2.5 catback.
Damn, you better buy it quick before I buy it all and replace them with borla mufflers and sell them on Ebay for a profit!!!
