I live up in Fort Collins and I have a Stage 1 MTM 98.5 1.8TQMS. My car is a daily driver, and I do not want to sacrifice any drivability. Any thoughts on adding a Miltek cat-back with K04 and 5Bar FPR with MTM stage 3 software. Any opinions would be appreciated. Thanks

I'd think that driveability wouldn't be impacted at all. The K04 is still a teeny tiny turbo, and should spool at a moments notice.

I love the Miltek exhausts, and if $$ weren't an issue I'd have one on the A4 right now.

But it might be cheaper for you to sell the MTM chip and get AWE's K04 kit- MTM is huge $$$ compared to the other tuners.
