Exhaust 4 rating: 7/10 - No video. This is the same Thorley 3" catback with a baffle installed to smooth out the exhaust flutter noise. Did its job well, quieted down the exhaust until you floored it and the BFI and Muffler sang a sweet WOT chorus.
Exhaust 5 rating: 8/10 - No video (yet!). This is the same Thorley catback muffler with no tailpipe. The exhaust dumps, which leads to the drone issue, but the growl is much better than the previous dumped exhaust. Maybe a turndown at this point, or reattach the tailpipe later....
I will make sure I throw some video up of the current setup.
Here is a video of our Magnum RT with the 5.7L v8. It has a few short exhaust clips near the end. It has SRT exhaust and the resonator delete kit with 4" Tips.
