Whats a good quiet muffler?

[tpruitt]

Right now i am running dual 5 inch stacks and i looking into ways of making them a little more quiet. The truck has 4 inch straight pipe all the way until the 5 inch stacks. I just want to make the truck quieter in the cab. What would be a good muffler to look at.





Thanks,

Trey

I think the donaldson 51" is pretty quiet, and its 4 in.

I'm using a MagnaFlow and I'm happy with the sound.

Magnaflow will give you a good deep tone while on the juice but not too loud. Plus the noise in the cab is minimal in my book.

shoot forrest nearing a PM... . a while back he insulated his cab so his stacks would not resonate as bad...

and then took his stacks back off



every muffler I tried resonated WORSE than just the uncorked stacks
