Whoops forgot to add pics, although I'm disappointed with the sound the tips look great.

Dammit. Bummer man. Good luck.

It's ok live and learn. Somebody on here has a quote that says "experience is what you get when you don't get what you wanted" or something like that and that's what this is lol.

I'm highly considering going back to a giant flopro oval they have 3 different models and previously I had the quietest of the 3. I emailed them asking if they have some an inside view of the different 3 models or a measured flow rate difference between them. I'd consider getting one of the louder models or possibly just go back with the one I already have and list the Megadrone 12599 for sale.

Rather disappointed the exhaust shop could only fit 1 set of mufflers without chopping the entire exhaust up and starting from scratch.

Quitters. IIRC, there's space for 54" of muffler from the front cross member to the rear axle.

Those do look good..!

Did you have to remove the curb feelers?

I agree to much in between I think I have a plan to hide 2 of the 3 sets of resonators and a backup plan if those don't quiet it.

Which I'm afraid they won't because I fooled around and did this today and couldn't tell a difference by ear or by the decibel meter which read 89db at idle 3 feet from the tips with and without the resonators attached. I think maybe with them before the muffler, and having a tail pipe to still travel through it will make a difference. Guess we will see Saturday when I get them welded in.

Also on rendition #20 of me myself tuning the truck with the new cam. Pretty proud of myself I've been hammering out a few logs a day running speed density only to fill in my VE table and spending considerable time hand adjusting individual cells. It's really fun kinda reminds me of a sudoku, which I actually hate doing lol.

Going across town tomorrow with a trailer to pickup a badass off road bumper for my backup toyota a family member wrecked earlier this week. I'm excited to log cells that I normally won't because I'll have the extra load. #supernerd

Good catch in the missing n't I'm a sloppy phone typer.

I might go ahead and order 2 of those and see how it does before I admit defeat. I'd like to go to a little higher class exhaust shop there's just no one open on weekends near me.

Thanks I'm super happy with those $19.99 tips best bang for the buck I think.

I sold the curb feelers to fund the multiple muffler changes.

Two of them 22" mufflers? You must really want it quiet! I say this because I have a 22" and 18" for 40" total. Now, even with no cats, it's now a little quieter than it was with cats and that one 18" muffler. It still has a great sound, just lower volume.

So no swangas? Bummer. Looks good, too bad the sound isn’t what you wanted. I’m in need of drone elimination on my Silverado but not sure if a heimholtz will do it since it dumps right behind the cab. Stupid truck has zero room for exhaust. Sounds great when I’m getting on it but at cruising speed it drives me nuts. I also found out I’m no good at exhaust. Wish I had some of @Doubeleive ’s skillz.

Well 2 because dual exhaust so one on each bank. Then possibly weld the ultra quiets directly to the mufflers for extra decibel drop since I already have them. Something like this even though this is on a silverado. I believe these are 5x9x22 magnaflow.

Also gonna see what can be removed from down under. I wish I had done the coilover conversion already because then the torsion bar crossmember could go bye bye.

Those AP brand are straight through design with sound absorption packing correct? Basically knockoff magnaflows?

Nope no swangas this week. With little space idk what you can do. They need to make mufflers that are built into 90* bends for more packaging options. I'm no good at exhaust either it really needs to be done on a lift. Laying on your back welding and trying to fit stuff is nearly impossible.

my kind of modding

 

[Dantheman1540]

my kind of modding

I have the brackets and some other parts to do it. Just need the coilovers and I'll be ready to go.

 

[randeez]

any idea what size you need

cause i have an extra set of single adjustables, they take 8" springs iirc, i should have like 800+lbs springs for em

they were too short for mine but may work for a torsion bar swap truck

 

[randeez]

15" fully extended, ride height around 12"-13" should work fine. May have a few sets of springs would have to look thru "the inventory"

I really have no idea I haven't measured or even researched it for this truck. I will measure tonight because I'd like to take those off your hands and free up muffler space!

 

[randeez]

and looks like those are 10" springs, im not sure what size are needed for the tbar delete

you must mean @iamdub lol

 

[Dantheman1540]

and looks like those are 10" springs, im not sure what size are needed for the tbar delete

Looks like ride height is right at 14" from the top stud to the bottom eye bolt. The eye bolt brackets add 1" at the top and probably around .5" at the bottom but I also have a set of the stud top adapters which eliminate that 1" at the top if need be. I also have a set of 8" 1,000lb springs but I have no idea what size spring is needed that will require some more research.

Gonna PM you about making a deal.

Also I just measure exhaust area to play with and I have right at 18" from drive shaft to frame and can fit a muffler with a case that is 24" long, lastly from body to bottom of frame rail is 9". I looked on magnaflows website and they have a 7x7x24" round, chambered but straight through muffler that is under $100 and 2 should fit nicely without hanging below the frame.
