Guys,

This Spring I will be adding full bolt's on to my 65,000 mile LS1 Camaro. These are my plans:

LS6 Intake
Speed Eng. LT's Race
(Delete EGR-Air)
TSP True Duals (Scrap the Bullets)
Black Widow Pro Venom 250-series Muffler

Future plans: H/C, and to back up the power a S60

So, doing some research I wanted to step away from all the normal exhaust builds and try a newer muffler company.. There's not a whole lot of info on Black Widow exhaust, but I believe they should sound amazing. Once installed I will report back with some video's, sound clips, dyno pulls, etc. Hope fully this will be a winner, and still produce good power.


Just a couple of clips that turned me on to them...

Black Widow mufflers sound amazing on LS cars from what I've seen and heard. Honestly I don't think you could go wrong M-Z28

Hoping to provide the LS1Tech community with I little review of the Black Widows under a ls1 bolt on car.. My brother has ran just about every muffler option and the sweet thunders, classic chambered, and borla's all sounded amazing. I'm just trying something new and would like to see if they have little drone as they claim.. I'm excited about this build. All components are ordered except the mufflers.. Hoping to have it on the dyno within a month..

The Purple 55' sounds amazing

I like the sound, but they seem very similar to a flowmaster. Definitely a chambered muffler given the welds on the body of the muffler in the video showing assembly of the mufflers. Very curious to see the internals of one.

^^this......if the flow is there, i'll try a set.....sounds like they've got good pop to them....should be able to hear the cam really well on idle.....they remind me of a cross between Flowmaster and Powersticks

Have you seen bench flow test results? I've been searching and here's what I've come up with so far:
2014 Silverado stock muffler 312 cfm
FJ Cruiser stock muffler 312 cfm
Flowmaster 40 series 2.5" side/center 376 cfm
Gibson 2.5" side/center 380 cfm
Straight pipe was 421 cfm

Did anything ever come of this? Has anyone tried this muffler? I am thinking of running a true dual setup with these mufflers. Thanks for the help.

Bumping for updates, considering these but wondering how neighbor-friendly they are. These seem to sound good but at some point for daily or cruising purpose too much can get tiresome.
