It's very loud and has run in the 6.50s in the ieghth mile. The old white Chevy truck in the background is the starting point for the 505 first start video I have on here.

Flowmaster demonstrates how its straight-through and chambered mufflers work. This video includes animated illustrations to show the sound-deadening principles behind its chambered (baffled) mufflers with delta design as well as its glasspack (straight-through) Exhaust mufflers. http://www.summitracing.com/redirect?banner=SocialYT449
Pontiac running 2009 big cam idle
1964 Pontiac Tempest, 2dr Post, 455 .040 over, 4X heads, Comp XE274 cam,Performer RPM manifold w/ Edelbrock Performer 800cfm, Full Pypes X Exhaust with RacePro mufflers.
Engine has Holley 3130/750 now and different timing set up. Made huge difference. I could never get the Edelbrock carb to work right. And yes the Mr Gasket header gasket on the driver side was leaking just 40 minutes after break in.

'70 chevelle dyno
'70 chevelle with 555 ci big block. 11:1 pump gas engine with a big solid roller, AFR 335's, vic jr., pro-systems HP1000 carb, 2" headers, 3" collectors, full 3" duals with x pipe running Pypes Race Pro mufflers. Electric cutouts are installed and are CLOSED for first run, OPEN on last run.
Car has a TKO600 trans and 12 bolt rear end in this video. GForce GF5R and Dana60 are going in this winter.
Engine made 792hp/701tq at the flywheel on a superflow engine Dyno. Chassis Dyno showed 618rwhp AT 5500 ONLY - data did not log up to the 6800 it was run to due to a Dyno error. Based on the 70hp increase from 5500 to 6800 rpm on the engine Dyno (horsepower peaks at 6800rpm), we are guessing we have around 670-690hp at the wheels.
Car will be back on the Dyno in the spring. Engine built by Mike Lewis of Lewis Racing Engines, Laytonville, CA.

Pypes Race Pro 3in. muffler, TBI Silverado
Stocker 350, for now... Just a Pypes Race Pro 3in in 3in out stepped to 2.5 90 degree. Before it was resonating real bad b/c I had in ending at the end of the muffler and the bed was just a resonator box, so I just got pep boys 90 degree and turndown and it is a completly different truck. I cannot hear/feel ANY resonance in the cab, at any speeds. I dont really like how quiet it is on the inside but it really does sound damn good on the outside. Also the Race pro flows like 680 CFM so its a zero loss muffler for me at least, I will try and post with a better camera, its just an easyshare C180
