i was under the impression the 6 speed didnt need a pedal commander. 100% throttle is %100 as fast as you push the pedal. commander ups that rate giving u more gas than your actually pushing giving the illusion or more power/ throttle response
i drove a pickup without a back window at all for 5 years. after i bought my corolla i still rarely use the rear view mirror. the backup camera and great side mirrors give me no need to look out of it
i didn't. after the cat theres small 1.75" pipe that will still be the biggest restriction. youl need to replace everything from the first cat back to see any gains i would think.
