Local shop is installing the 18 inch Magnaflow Wide Open muffler with a 12 inch long stainless, 3 inch diameter tip. They're cutting out the resonator and just slightly shortening the piping. The dealer has told me they will warranty this as long as it's done at this particular shop with the Magnaflow (I imagine cause Magnaflow has a lifetime warranty). Anyway, guys at the shop said we already have 2 1/2 inch piping and it's not worth going 3 inches and doing a cat back.....don't know if that's true but I'm saving about 200.00 dollars this way. Out the door, I'm paying 220.00 where as the full cat-back would have been close to 420-430.
I already have the Nismo cold air intake, and I have a throttle body spacer from airaid.com on order.
I'm driving from SLC to Portland, OR next week and I'm looking for maximum MPG. I'll let you all know how I do. My best tank so far got me 374 miles. With these new mods, and driving 72 in 6th most of the way, I'm hoping for close to 395-400. Wish me luck! :blackeye:
