Borla Mufflers Caused Power Loss
 

I own an '08 TL Base. I installed some Borla Pro XS mufflers today, and as I was driving back home on my daily 35 mile trip on the highway I felt my TL heavier and louder then usual. Any suggestions on what I might've done wrong?

**Previous owner removed resonator
**Exhaust pipe coming from the headers looks thinner then 2.5"... is that factory diameter?

I didn't take pictures... I was short on time and had a punctured muffler.

Your AF ratio is probably out of whack.

The pcm is probably trying to learn the new mods, I suggest disconnecting the battery for a minute. The car should feel better everyday you drive it
