I got a 08 6.7 with a 2nd gen manifold swap and s472. It's got 5 " exhaust and had a mbrp muffler then dumped right after the axle. It always had a bad drone after the swap. I added the 30" FTE and left the mbrp on and wow what a difference. It's really enjoyable to drive now. Boost, drive pressure and egt all stayed the same. Great product. :rockwoot:
