Car feels sluggish after catless downpipe
Yesterday I did catless downpipe and MHD st2 (91oct). The rest is bone stock.
During daily driving the car now feels kind of sluggish at low speeds vs stock. Is this to be expected? Most people talk about the noise and the smell (not as bad as I thought), but how about the throttle response? It is mostly noticeable in comfort mode, but even in sport/sport+ mode it feels like I must press the pedal deeper and wait longer for the car to get moving. |

Also outside temperatures are 5°F so intake temps are super low. But for warmer days I have a Wagner Evo2 on the way. |

I have the stock cat but after installing the Remus cat back I also noticed a pretty big difference in throttle response. It just didnt seem as fun. I did recently did get the latest Istep upgrade at the dealer and it helped but the low end throttle power just doesnt seem to be quite as good as it was before the exhaust. It definitely sounds better though!
