2018 Mustang GT

I had a Roush X-Pipe, air intake & tune done to my 2018 Mustang GT. The people at MM were excellent to deal with. They were patient, discussed options, reasonable expectations and delivered what they said they would. The car is more responsive, sounds great and the quality of work done is high. Thank you

The Roush X-Pipe combined with the Roush Axle Backs totally opened up the Mustang's exhaust, and it now sounds like a Mustang should!
