i have an off-road x pipe with roush axel backs. it is way too loud and i'd like to put on resonators. any advice on how to do it? i'm not sure what exactly the resonators will do, but i've been led to believe they quiet down the exhaust and remove some of the rasp. would i be able to put resonators on in my garage? i have all the basic tools. or would i need to take it to a shop?
My car has an automatic transmission.
