So i got my borla xr-1 part number 40085 finally put on my exhaust. Wow its is so much deeper. It also is quieter and deeper at idle up to about 2500k. Which i love because my camaro is my dd. It screams 2500k and up. I defiantly would recommend it to anyone with slp lm1. By the way does anyone know if gets deeper over time because it gets broken in?

I noticed my MagnaMouth has gotten deeper the last few months. They are both perforated core bullets... However, I "think" the packing is different between the 2.

Mine got a little louder after time (a lot louder after the H/C swap )

Mine is a little louder, but I don't think it's any deeper. Its already sounds like a earth quake rumble.
