I replaced my stock muffler with two vibrant 1118 resonators and installed a secondary cat bypass.
I think I need an xpipe installed to relieve some of the back pressure? The vid I want to upload is too large and sounds great on start up and idle sounds okay when you’re standing back, but up close as you can hear in this short clip isn’t great.
