Sixtus, WELCOME! I would call Mike at Hillbank 619-647-3244. He not only installs and sells Mustang suspensions, he races his S550! Nice guy and knowledgeable too! Keep us posted on your car's progress.
Gabriel, You might want to check with Hillbank Motorport in Irvine. I know they sell Roush parts. Their phone number is 949-900-1960. The Mustang expert is Mike.
Hey Canyon,
I'm hoping to be getting rid of my exhaust in June. It's off of my 2017 GT with 6,000 miles. Let's keep in contact if you don't find one sooner.
Mike, I can do both jobs. Not a problem. I agree that the Dynamat should go in regardless of installing a Subwoofer or not. I need an 8th day of the week .
Mike, It's all about the my budget. I have to choose between the subwoofer and amp or an exhaust system. U have to decide which "sound" is most important!!
