Use a 4-2-1 header with an O2 bung in the primaries (ala neuspeed N2, or even an OBX or something) and you could either use an O2 sensor emulator for the second O2 sensor, or extend some wires and put it in the equalizer pipe.
Holy pointless!
I hope you are joking.
I already replied to HAZE's PM, but figured I'd post here if it helps anyone else out.
I paid $200 for a couple TL-S mufflers, but they were only about 6 months old.
I paid $200 to have my existing 2.25 piping hacked off near the rear axle, and split into 2.0" piping leading to each TL-S muffler and hangers. I may have lost a bit of low end, but I'm not sure, so it's pretty much negligable.
It's just a bit deeper than stock, but still nice and quiet.
I just like the look of duals. I also like the look with two tips on a single muffler like a lot of Honda/Acura cars have like Prelude, etc.
