Only high flow diesel cat available at the time, I wanted this truck to be 100% legal.

What made you choose this particular product?
Magnaflow quality for a custom high flow exhaust.
Is this your first time buying from this brand? Did you consider other brands?
No, I prefer magnaflow or flow master because they are easy to find, affordable but still of a reasonable quality. There are no kits for this car, so custom pieces are needed.
Was it easy to install? Any installation tips that will help others?
Yes.
Once you've had a chance to use the product, did it meet your expectations?
Good product. O2 sensor still good after 3 years.

What made you choose this particular product?
On my previous car I had simply installed one of these universal Magnaflow mufflers and deleted the stock resonator, and it sounded perfect. Quiet like stock when cruising, but has a nice deep tone when you get on it. I wanted that again.
Is this your first time buying from this brand? Did you consider other brands?
No and no! ... well, maybe Vibrant, but I knew MF would work for me and it looks nice.
Was it easy to install? Any installation tips that will help others?
Sure it was easy, I went to a muffler shop and shoved money in a guy's face to weld it on for me!
Once you've had a chance to use the product, did it meet your expectations?
I still need to have the stock resonator removed, so it still sounds mostly stock. It provides a nice tone, but is quiet because of the amount of sound deadening material - which is what I wanted, so I'm definitely not complaining. Just need to get around to having the resonator removed to make that nice tone a bit louder.
