Pypes Turbo Pro

That J pipe - is that welded into your exhaust aft of the muffler? And is it a closed end pipe? Couldn't tell from the photo bur it looks like it is. And you have one for each exhaust line? I'm impressed by the engineering but I'm going with a quieter muffler rather than that. I'm no acoustical engineer and it's just hard to believe that drone is that hard to solve. Back in my younger days, I admit a long time ago, we bought whatever performance muffler was available and drone was never mentioned. Thanks for all the help guys.

Its welded to the tail pipes after the mufflers both sides. There's a welded in cap on the adjustable end. If you look at the Pypes lineup of mufflers they say the Race Pro is their quietest. It's a straight thru packed like a Magna Flow. Before the J pipe install I tried bottle resonators in the mid pipes behind the X pipe ,drone. Then I tried Magna Flow chambered mufflers, sounded great but still droned right at cruise 1500/1800 rpm and idle. J Pipes (helmholts) no drone at any RPM. Back in the day we wanted as much volume and drone as we could get. :lol: not so much now I'm older.
