Adding a Jones Exhaust MF2469 muffler in an attempt to minimize drone and “rasp” from my Speed Engineering dual kit. Eliminated 100% of the rasp, but seems to have just moved the drone to another rpm range. Boost pressure remained the same, so we can assume not restriction was added.
how much would u sell it for ?
nice mufflers and motor 👍
Time for J pipes,or better just replace old mufflers with some bigger bodys.Still happy with cam choice? Gather new cam and delete when forged goes in.
What kinda bed cover is that
And how much for the truck
Glad to see you are back keep us some new videos coming please.
Still have the cutlass?
I’m literally about to go through a similar process with my ‘new to me’ 2015 Sierra RCSB. Going through your whole series I think I’m going to fit Speed Engineering LT Headers and there True Duel Exhaust. Engine wise, after viewing your cam install videos, I think I’m going to go 210/230 – .572/.572 and just run LT1 valve springs. I assume you used the Phaser Limiter Kit (Part #5456) to limit it to 22`deg? Instead of a whipple I’ve got a LT4 blower and the conversion parts. I figure I may as well keep the AFM/DOD stuff too keep the install easier and worry about the delete and everything else if the 5.3 blows and I drop a 6.2 in instead. Looking forward to getting it all done based on the results you’ve had.
