^ you can add an HFC Module after the ART pipes and effectively make it similar to HFCs, less noise no TP exhaust fumes
Sam, the sound is a bit too raspy for my taste with my stock exhaust but I plan on getting the MD xyz pipe with resonators to remove the rasp...
The increase in performance is definitely there, and you can notice it even more on fwys at higher rpms, its a blast to get on the fwy everytime

This would be pretty much the same thing as he already has...with Resonated HFCs, an 8" resonated build right into the HFC piping.
Otherwise you'd have a resonated Test pipes(ART PIPES)...and then add an entire HFC after it?

^ It would be ART pipes + XYZ Pipe with HFC module at the end of it (It would be 1 cat vs our stock 2)

Main reason is to reduce drone/sound. I really don't like loud exhaust at low rpm. I read/kinda heard that TDX is actually quieter with ART pipes than any aftermarket hfc.
I live in Alberta Canada. We don't have inspection
As for rasp, it's barely there. I only hear it on higher rpm on cold days only. But nothing too much. Barely there
