Is the roush catback much louder than the stock s550 exhaust? If you have a roush are you happy with it? What other exhaust do some of you guys own and are happy with it? Thanks Dan
I have used synthetic Mobil one in most vehicles I have owned. With my 18 mustang GT I am thinking of pennzoil platinum 5w20. I don’t think I want to go with a motorcraft semi blend unless someone has a reason for doing so. All info is appreciated.
It has a heat shield wrap around it and connects with a plastic clip to the bottom of the car. Just curious if it is a port to the ABS or something else?
