Installed a Summit 16" polished muffler on the Ram last week. Already had a CAI so here are my comments on the combo:

By leaving the resonators on I have a good smooth sound with NO cab noise.

Mileage (500+/- so far) is up to around 19.5 on the highway.

For $56 plus minimal shipping it's a great deal.

 

link to muffler?

 

Is the Summit muffler a "knockoff" of a flowmaster or magnaflow? Got a pic?

 

Or a sound clip?

 

i have summit turbo mufflers on my 71 nova. they sound amazing. ive been hesitant to put it on the ram tho even the price is right.

 

yeah lets hear it

 

^x2^. I want to hear it now too.

 

yep, we need a sound clip. I was asking about these a while back because the price was def. right...thanx for the info! was yours welded on or clamped?

welded on, through hooker headers. video doesnt do it justice, definitely much much louder than the video makes it sound. but yea its more of a straight through glasspack sound rather than the flowmaster deep drone

Mine is welded on. I'll try and put together a video with sound. It is fairly quiet.
