Okay, I bought a 2003 Mustang
GT earlier in the year. Car has only 37,000 miles on it. I'm currently updating and customizing the car.
I've got a metallic rattling coming from under the car from 2000 RPM and up, so I'm guessing the cats are bad which is great since I want to get set up with some HF cats.
Can anyone give me some input on UPR's Catted Xpipe? Anyone install it, and how well did the install go? How does it sound? Any problems with inspections (I'm in Jersey)?
I'm sticking with the OE catback for now, and I will still have the stock manifolds on. If I had the money, I'd install some shorty headers at the same time, but I'll do it next summer.
