1997 Chevy C1500 True Dual Dynomax Super Turbo Mufflers

1997 Silverado with 5.7L Vortec CSFI. All stock internals. K&N Filter. Flowtech Shorty headers, stock head pipes, magnaflow cats, true dual 2.5" cat-back, no h-pipe/x-pipe, Dynomax Super Turbo mufflers, dumped at the corners (as you can see). Pretty quiet at idle and not very loud with revs but nice rumble.

Its a nice cool 97 degrees out and 63% humidity on this lovely late spring day in southeast Texas. Not that hot? Not really but its only 10am.

Hope yall like the vid. This was shot with a digital camera, so its not HD or anything. I didn't want to be like those guys that are like "I'm gonna stick my cell phone right next to the tip so its crappy quality AND you can't hear a damn thing, so its really gonna suck but I'm gonna post it on Youtube anyway, durrr!"

Update: I changed from the Super Turbos to Dynomax Race Bullets a few months after this vid. I couldn't hear the turbos from inside, so I had to change. I also dusted off an old hypertech progammer and tuned for more power, higher rpm limiter, different shift points, and harder shifts. Thanks to the hypertech, i was getting 14.5 to 15 mpg. I now get 17+mpg even when hot rodding it.

i have a 1997 sierra 350 and i was looking at flowtech shorty smog headers, how do you like yours and would recommend them??? and HP gain,sound change??? and any problems leaking or cracking?

[FlushieJohnson]

@youdragon I installed my headers by myself in an afternoon. They bolt right up no need to grind the P/S bracket. The factory head pipe studs took a 3/8 impact to remove and the pipe at the back of driver side manifold is a pain to get the threads started. I noticed a little more power and a slightly throatier sound. You MUST spend the extra for ceramic coated, they last much longer and look better than painted and dont forget to torque the header bolts again after a month or so to prevent leaks

i got a 98 1500 i want to put headers on did you notice any difference? and with the high flow cats did your check engine light come on? thanks

[FlushieJohnson]

@fordgtrcr There is a slight difference in sound and power, as the stock manifold is pretty restrictive. I did have a problem with catalyst efficiency codes when I had high flows on it. Now it has heavier cats, similar to factory cats, and it throws no codes.

you need to take that hypertech and throw it in the trash, they are junk, send the ECM in for a real tune.
