Pros Easy install, very light (they weigh 9 lbs each), Sound is unbelievable. Deep rumble at low rpms and they scream as you progress through the rpm range. This is my third axle back, first roush then borla s type. The outlaws put these to shame IMO. There is drone right at 2k but I dont have my resonators anymore so thats the main reason. But the drone that is there comes and goes quickly and is not bad IMO. Wish I could give it more stars. Be warned though...these are pretty dam loud but its a awesome loud!!!!
These are the loudest mufflers you can find and boy do they sound good. They growl like a angry beast. Only downside is the drone that comes at 2k rpm but its not horrible. I would never consider a different muffler after hearing these on my car
