Black Widow Race Venom Muffler 3" Inlet/Outlet

This muffler I installed on a 1999 GMC sierra 5.3 L V8 with 3 inch pipe coming from muffler to exhaust tip. The overall sound and performance of this muffler.This muffler sounds really good at idle and cold start, and it really rumbles at low idle not that LOUD but a good sound. I noticed at higher rPMs, and on the highway it is not loud at all. It’s almost like you can barely hear the exhaust, which is a good thing. I guess my only downside from this exhaust is, I wish it was a bit louder but if you want, the aggressive sound at a low idle, this muffler does it, but at a higher, idle and RPMs on the highway and through town it’s not that loud, but it has a little bit of aggressiveness, so if you were looking for a loud exhaust, I would not suggest this exhaust muffler, but that is just my own preference. Other than that the muffler exhaust arm performs very well, and there is no packing/sound dampening in the inside of the muffler, it has channel ways that direct exhaust airflow to have a unique, aggressive, sound, but as far is inside the muffler, there’s no packing or anything you can see straight through the muffler.

This motherf***** sound bad. All the girls at the local sonic drive in immediately get soaked up when they hear my 5.3 Chevy Hoe pull in. They want this d***.

Not the loudest but that's okay. Great quality and sound.

Great ! You can hear your cam

The media could not be loaded. Installed this on my 16 sierra with a 5.3 and removed the rear resonator and kept the 3rd cat. And also install a Range Technology AFM/DFM Disabler and it sounds amazing and no drone at all! Highly recommend!

Awesome powerful sound. Nice and low at idle, a bit louder at 2-2200 rpm but tones out at highway speeds. Really love the sound of these mufflers. Howls at full throttle and barks when provoked. 2014 Challenger SRT8.

Fast delivery, arrived as stated and is exactly what I wanted..

I wish I had done more research on these mufflers. I put them on my LS swapped and cammed C10. Full 3" true dual system sounds like garbage under acceleration. It sounds like a straight piped Mustang hauling ass through downtown. They are not for me.
