Anyone know the part numbers for the "correct" aftermarket mufflers for a D2? I'm not necessarily looking for a whole kit, just the muffler details (i.e.- inlet/outlet size, location, model, etc)...

Other than the Magnaflow's and Borla's, what other options have you guys tried?

 

Local muffler shop, $100 out the door, center muffler only.

 

This is what I did. I removed the resanator, which is the center muffler, and left the O.E.M, at first I was disapointed, but after a while it ran even better, I think the computer needs time to read the changes, such as back pressure and air/flow.She sounds great and a little faster off the line.If the muffler needs replacing, I would get a Flow Master three chamber, they arnt to loud, but have a nice rumble.With these new mods I would recomend E-3 spark plugs.Spray your mass air flow censor with the propper cleaner, and even new plugs.

 

Wait......so the big, 10 foot long muffler is the resonator? Interesting....

 

The center muffler is the muffler, the rear "muffler" is the resonator.

well I'm confused, I asked the muff shop to take the resanator off and they took the middle one out.O well it works well.If you look in the English Land Rover mags they sell a kit to replace the center Muff out with a straight pipe.

 

disregard most of this.

the rear coffee can is the resonator. cut that out. the center coffin is the muffler. i swapped that with a magnaflow muffler. sounds good and engine chugs along at less rpm and upshifts sooner ever since i swapped the cans. seems to pull a bit easier.

dont know anything about E3 plugs but most love iridiums and +4 boschs.

also avoid cleaning the MAF sensor as most cleaners (even MAF safe) will usually cause more harm then good to the MAF units on our trucks.
