what resonater are you running? My MBRP is not helping a bit with these 6" miters. worked great on the 5" aussies. Starting to wonder if its the cut and not the size that is causing a drastic noise difference?

Sounds awesome. I love my stacks, they have an acquired sound and can get pretty loud!

I'm thinking I want to do this in the spring time so if there are any good links you can give me to places that has the stuff I would appreciate it.

The MBRP kit I bought was a full turbo back that also included a 4" downpipe to replace the 3 1/2". I believe it is a full turbo back for 04.5 and up also.

If you want it to be loud and have a larger pipe but are worried about hearing it in the cab run it right out the back.

I have a 5in right out the back,no cat,no muffler,and it's pretty quite inside,if you drop the windows it's loud as heck.

I like the volume of the 5" stacks but these 6" are obnoxious. Might try the drop-in mufflers G.R. sales. If they can bring the noise back down a little with no drone I'll be happy

donaldson actually makes shorter ones. head to the big rig parts dept. tell them what diameter in and out and you want 24 " long.
