Yes it's not bad driving around I have the tailpipe on it now but my girl friend and neighbors haven't complained yet lol

 

Magnaflow mufflers get louder after a few hundred miles. Magnaflow calls this a break in period.

MagnaFlow Performance Exhaust - FAQ, Frequently Asked Questions

 

Here was the cat back exhaust bought off summit for around $230 came with a stainless steel muffler

 

The packing in my Magnaflows blew out within the first 100 miles. I could rev it up and watch the chunks of fiber material blow out the tail pipes. Seems to be a common complaint with them if you Google the topic.

 

I would typically use a magnaflow muffler, but my wife won't ride in my truck with it loud.

I bought a Dynomax Ultra Flo Welded Mufflers 17557 - Summit part number - WLK-17557. It's pretty big:

Case Length (in):25.000 in.
Overall Length (in):30.000 in.
Thickness (in):8.250 in.
Width (in):11.500 in.

Here's a video of it idling:


Here's a video of it driving from in the cab. I two open dump wastegates, which is why it gets pretty loud. I will say that with the windows up I can use my hands free and talk without anyone having an issue hearing me.

 

Mine is a turbo 4.8 with MBRP 4" with a HT1 cam. no drone and sound pretty good.

Full throttle

 

boosteds12 do you have any pics of how you ran the exhaust? I, looking at a bed exit like you have

 

Awesome videos guys keep them coming im sure this will help others decide on there 4in. exhaust systems

 

Yeah, that is awesome how quiet it is for being 4 inch and a few feet shorter than a reg exhaust.

 

Anyone running a Jones Maxflow muffler? I have one on the Tahoe and it sounds amazing. Deep tone, no rasp, etc. The muffler is stainless, great quality and very inexpensive to boot.
