: remove muffler on my 02 lb7? lose any power? badass1g 10-17-2006, 11:36 AM if i just kept the stock exhaust and removed my stock muffler, would i lose power due to not having any back pressure? ive read somewhere that someone actually lost hp on the dyno from doing this, the truck doesnt have a cat to my knowleadge. thanks redfish 10-17-2006, 02:14 PM Cut mine out, and many others have too, I thought it was an improvement, but then you'll have the DDS with an LB7 badass1g 10-17-2006, 04:24 PM DDS? would i have a DDS with an aftermarket exhaust? ob_1jr 10-17-2006, 04:32 PM when I cut mine out, I thought the turbo spooled faster....liked the sound too! SaguaroKid 10-17-2006, 04:36 PM I don't see how you could lose any HP, lots of people do it. I think back pressure is an issue with gassers not diesels. Therorically you should get more HP and less EGT. badass1g 10-17-2006, 11:59 PM sweet thanks guys, i cut it out and love the sound, sounds so pissed off now.. best/cheapest upgrade IMO BullydogPowered 10-18-2006, 11:03 AM sotp felt like i lost power removing the muffler and doing the stack. track times (although it was cooler than the last time at the track) show otherwise. | ||
