this! i have the ataks + catless headers and the rasp real, resonator kills that instantly. would love to find a 3in resonator if someone makes one
Dynamax makes a 3" resonator pipe i do believe. That is where ive been looking. My catless headers with the Gibson catback is a little raspy in the higher rpm range.
They definitely do. 12" and 16" body, 4" diameter case, 3" ID inlet, outlet and core. They will definitely kill all the rasp.
Boom.
Those things are zero restriction straight through.
Really? Do you run them or have you?
Yes as my only mufflers lol. Mine are these 18" case 2.5" ID. I'm running them mid muffler (rear mufflers and stock resonator are gone). Stock cats and headers for another two weeks until my LTs go on.
Nice. I may order a set soon. I'd like a slightly deeper tone and less rasp on my setup. It only gets worse with LTs. Trust me lol.
Oh I know I had LTs on my 13GT with catless mids and GT500 axle back. It was really loud once the LTs went on and the stock cats came off. I'm putting 3" inlet/outlet 6" long case mini race bullets on the midpipe where the cats would normally go to further tame it and I can still add rear mufflers back on it if I ever wanted to. For the size they are the dyno max bullets do a great job of controlling rasp and drone.
I had both catless X and catless H on my 13 and I honestly liked the tone with the X pipe better it really screamed.
I bought a used h pipe in hopes of trying this, come to find out its not a 3" tho. My whole system is 3" from headers back to mufflers. I can't seem to find one that IS 3" without a $280 price tag.
Do you have a video?
I had that exact setup on my 2013 and it was a tad raspy. I'm my opinion sound wise chambered mufflers (GT500s are as are stock) are not ideal on long tubes sound wise they tend to be more tinny and raspy than straight through mufflers of comparable size. If you want to keep the GT500s though welded or clamp in a couple 12" long dynomax race bullets after your X/H pipe. Cheap and extremely effective solution.
