I have a 2008 Chevy silverado with a 5.3l and I was wondering if any of y'all run the black widow mufflers on your trucks. I'm getting ready to redo my exhaust after a cam swap and planned on going with Texas Speed LTs and ORY into a 3" center si/center so black widow. I've searched all over youtube and found a few guys with nbs 5.3's running 'em, but it's hard to say what their setups are, which series black widow they're running, whether they're catted or not, etc. They also have a new Race Venom Muffler that's designed the same and I figure is probably quite a bit louder than the 250's and 300's. Any and all help would be greatly appreciated.

 

i have a friend that has one on his 5.3. he has cats and all that and he's happy with the sound. i don't really like it. it has a really high pitch rasp to it that I'm not really into ill try to get a sound clip for you

 

I've got a Venom 300 on my Silverado and my Girlfriend's too. Both sound great. I'll eventually get one on my Sierra.

 

Sure sound and look just like a flowmaster to me but with a much higher price tag

 

If they're catted they don't sound any different than any other muffler IMO, but non-catted...these things sound pretty amazing. The other huge selling point is the design, this is a quote from the FAQ section on their page: "Our mufflers do not have chambers. Chambers are created to channel airflow in an attempt to control back pressure and create a specific sound. Our mufflers have a non-restrictive, straight through hourglass design created by two sound deflectors that actually aid in pushing airflow out of the muffler at a greater velocity than upon entry." This was what sparked my interest and had me wondering who runs 'em and how they feel about 'em.

 

 

i have a 99 nbs 5.3 stock manifolds and ory pipe, into a venom 300.

this is how i have mine set up.

 

I'm sure it will sound good. My friend has the Vemom muffler on his Titan and it has a cleaner sound.
