SSenvy Posted August 12, 2012 Report Share Posted August 12, 2012 So, after looking at our stock Muffler, its a DI/DO with a y after the muffler that goes into 1 pipe behind the rear tire correct? I want to keep my exhaust stock everything, and just put a new muffler in. My question is, theres a lot of magnaflow mufflers. So dilema is, do i keep the DI/DO style muffler, or go to a DI,SO muffler, SI,SO muffler? Does either of those affect the sound? Thought i read, there are Magnaflow bullets also? Theres so many differant Muffler lengths, and man.... never thought there were that many damn options lol.I really want a Low deep rumble with this truck, and want to be heard when im pouring it on. Suggestions would be greatly appreciated I dont wanna be sacrficing performance, and Gaining only slightly better sound if ya know what i mean.

cb2big4u Posted August 12, 2012 Report Share Posted August 12, 2012 I have the magnaflow magnapacks. I'm guessing that's what the bullet type is. I can vouch for those and say they will give a very loud and raspy sound. I personally like it. In your case I would go with a Di/do. What size, maybe someone else can chime in on that. Mainly just wanted to make that first statement. Sent from my ADR6425LVW using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

asullivan Posted August 12, 2012 Report Share Posted August 12, 2012 Isn't it the shorter the muffler, the louder it is? Quote Link to comment Share on other sites More sharing options...
MARTYW Posted August 12, 2012 Report Share Posted August 12, 2012 Yes, the 18 will be louder than the 22. Magnaflow part numbers are 12468 for the 18" and 12568 for the 22". Both sound good from the sound clips I have heard. Quote Link to comment Share on other sites More sharing options...
