Borla Woes - Any Advice on this Updated Cluster?

Absolutely, yes! If you get a catted header from SW. They will pass emissions testing. I also have had SW, and the sound is amazing. However, I found that moving from the 1-5/8” Borla tubes to SW 1-7/8” i lost significant low end torque. Which I did not like. But that rumble of SW! Wooo! Threw no codes that I can remember!

SW's mufflers are loud and with interior drone. On my Scab anyway. Removed the SW mufflers and installed longer Magnaflow's which are quieter and some less interior drone.

I had Borla S-Type Exhaust hooked into Headers. Drone was off the charts loud so I had to reconnect OEM resonator. Next time will put on a helmholtz resonator or J-pipe.

Yes....my Borla system has some pretty significant drone for sure....since Im returning to stock manifolds/cats soon...I guess that will solve that haha...although Im keeping the S-Type exhaust..

Right now, Im running the Borla exhaust from stock manifolds without resonator. Virtually no drone, but boy I do miss the rumble of headers. It is on my list of mods though.
