Mufflers

Twistgrip · April 17, 2008

Hey guys just thought I would let you know I found a oem direct replacement muffler. I have megnaflow mufflers and don't want the noise, ordered part number2500. www.flopro.com

cool.. Flo-Pro has been making them for awhile but they are way too quiet for me.

Just a little feed back, if you are looking for whisper quiet exhaust I am very pleased with it. No cab noise at all!

Thanks for the info, my stock muffler is going south and I will need a replacement soon. What did it cost you if you don't mind telling? I checked out the website and they don't list prices.

I just bought it through my local muffler shop and parts and labor were $230.00. He didn't mark up the muffler but I think there around $165.00.

I thought the GM OEM exhaust systems were all stainless steel??

How many miles did your truck have when the muffler went bad?

I had a Gibson on my old 4.8 and it sounded way better then my Dads 5.3 with a Flowmaster 70. I have contacted Gibson they don't offer a wide range of systems yet for the NBS 2500HDs. They did give me a part number for the Muffler that will replace the factory unit. Apon asking I found out this is the actual part number there kit will use. I am going to weld this muffler into my factory Exhuast system. I have a 08 NBS 2500HD 6.0 Ext cab Standard bed. The earlyest they may have a kit ready for the public is 3-4 months.

Gibson Part Number: 788040 (Add an S to the end for stainless)

Round, 4'' In X 4'' Out X 8" Round'' X 24'' Body Length X 30" Total

haha Yup, that's me! Joined here after I picked up my 1500HD. Love the truck! Wish it had alittle more growl... but didn't want to cut off the stock SS exhaust system like I did on my 99 Tahoe and had to replace that 3 times from rust.

Go the Corsa route! You can't go wrong with Corsa. Last time I looked on eBay there was a Touring system for a 2500HD (which will work on the 1500HD, just have the muffler shop change the 2 hanger locations) for a buy it now price of only $375. I had one on my 1500HD and as soon as they offer one for the NNBS, I'm getting one for this truck.

Nothing like making a new truck ghetto !!!

Even better...........Why not just cut off the cats and muffler and just run

off the straight pipe from the manifolds?

Should be loud and ghetto enough then huh?

Under $400 for a full S.S. exhaust system would not be bad. I'll have to keep my eyes open for a deal like that. Thanks!
