Why is my 2015 5" exhaust so raspy sounding?

WatchTryst · Jun 29, 2016

The exhaust note on my 2015 running SCT Extreme tune sounds awfully raspy, below is a video of startup and idle sounds. I have seen and heard other trucks similarly configured and they sound noticeably different. :shrug:

Is this normal sounding or do I need my ears checked/ :shrug: LOL

How long have you been running the new tune for?

1 hour LOL. Not much testing needed, if it doesn't close the veins at idle. It's working Lol

Is this just a 2015+ thing? My 2012 "hisses" intermittently, but not constantly like in the video.

Does it when the engine is cold, helps it warm up. It shouldn't do it if it's warmed up, and the 2012 did the "jet taking off" sound every once in awhile, something about cycling the vanes helping to keep soot build up down? Idfk, but I didn't notice it at all on my 2012, and my 2015 I notice it all the time. Both trucks were/are 5" strait pipes.

I think the hiss at idle sounds mean. However on my latest revision of my tunes p!p I has turned off. I also noticed a great reduction in hiss and raspy note since my muffler/resonator install. I honestly miss the straight pipe. But it is much easier to fly by under the radar without the look at me volume of the straight pipe.

I love the sound when on the throttle, but not so much at idle. lol

I wish *sparton* would turn it off on every single tune regardless of what rev or level or tuner. Just turn it off!! LOL

I like the sound of open vanes with the new punch it tunes. I also have the v8 files with the vanes closed. They will send you them if you prefer the hiss
