e55 Gutted cats questions?
Has anyone gutted the cats or replaced the VERY RESTRICTIVE H-Pipe with an offroad (catless) pipe on there E55? I heard it unlocks tons of power.. Is that true? What's the hp gain exactly? What does it sound like after?
I'm very interested.. Any thoughts
Thanks

not always removing primary cats add power ><
one of my freind removed them and his car became weak @@
for a week it was stronger and faster but after that, it really lost alot of power.
