Im running Spintech muffler behind a 383. They sound good except at idle, 700-800 rpm. Anyone have a suggestions on how I can get rid of the drone? Thanks
Can't speak for Spintechs.....However, my Dynomax Surper Turbos are as quiet as you will get at all RPM's.Im running Spintech muffler behind a 383. They sound good except at idle, 700-800 rpm. Anyone have a suggestions on how I can get rid of the drone? Thanks
im running 2 1/2 pipe. Not sure on the timing. Im idling at at 700 rpmsI've got spintech's with a 383, no x or h pipe.. no drone, unless I set the idle to 1000 rpm. I have it set at 800. I will say this, they are LOUD as soon as you get on them. I love the sound but it gets a little old after a while.
I will say your mufflers seem to be a bit further back than mine. What size exhaust? timing and idle?
I am running some old Dynomax resonators that I installed in 1994. Unfortunately they are on a 65 Chevelle that is tubbed, so I have lots of room behind the tires. They are oval shaped, like a small turbo muffler, so these same ones would not fit a stock trifive. However, even something as skinny as a glasspack would knock down a lot of resonance. Some late model Suburbans use a very narrow resonator, so that may be a good place to start.Driver, what brand or model of resonator are you running? I'd sure like to quiet my exhaust down some while at cruising speed.
