Thanks for sharing the video and tips. Realized that a catted down pipe vs de-catted you would leave some HP/TQ on the table but didn't know about the smell. That in itself would be a deal breaker for me unless I was full out racing the car. The extra numbers aren't worth it to be able to drive and enjoy the car on the street.
I'm really happy with the downpipe no smell from it. I'm mainly doing the mods because I can't leave any car I own alone, these particular mods open up the exhaust for higher than stock boost levels which I'm pushing.
