That's a good idea, I looked at that but the fuel tank blocks the left side, not enough room between it & the driveshaft. I don't really want to run two down the right & then switch it over. Right now I've replaced the 2 1/2" section with 3" tubing, have a 3" Magnaflow coming to replace the stock muffler. Then it will be 2 1/2" from each bank to the 3" y connector, then 3" the rest of the way. Btw, a 3" system has more area than a dual 2" system.
