1970 SS 454 Chevelle Dynomax Ultra Flo 17547 Rogers Exhaust Shop Fontana

Rojer's Exhaust, Fontana, CA (909) 823-0009 1970 454 SS Chevelle 3 inch Dynomax Mufflers #17546 20"case X pipe . Removed Flowmaster 40 New pipe X pipe tp Mufflers and reused previous 3" pipes after muffler. Fixed up the old pipes to look brand new and rebent and welded tips...AWESOME WORK!!! Killer job. These guys ROCK! The Dynomax Mufflers make the car sound clean and worth a million bucks compared to the flow masters that were too loud and sounded like marbles in a tin can. Highly recommend the Dynomax and Rojer's Muffler!!!

I took a bunch of video of the completed product while the car was on the rack, but I can't find it....Durrr! I'll try to get Roger to put it back on the rack and get some better shots of the final product.

See More Videos on my channel of the before and after. RATE it!!!

how much in compression  you running? I am running 10:7 and having the same problem with the flowmasters being to loud

[dutchboy25al]

@challenger706 10:7....Imagine that! Me too. If you like the Flowmaster sound, check out their 50 series in Stainless steel, 3 inh for a Big block. I wanted to try something different....I like these, guess I'll never get a chance to try others on this car. I'm sure these will outlast the car. Guess I'll have to build another car!!!

I'm a Mopar guy but that thing sounds intoxicating!

I love Mopars too!!!! Currently drooling over a 1968 Charger...but i have a garage full of Chevy parts and engines.

Dude I've listened to both videos....and it's a toss up. The car sounds badass either way.

[irvinemuscles]

Awesome sound. What are your cam specs.

I just hooked this up to my surround sound and started to cry. Now I am thinking of changing my ring tone from the Mazda 787B to this.....

Sounds like a true 454 should, like the world's coming to an end. Ever drag it or is this mostly a show car?

[migselv16896]
