i just put the dynomax super turbo kit on my 2001 screw 4.6 its a si/do. the install was fairly simple the hardest part was gettin the old system off. "ford cranks those clamps tight" . it sounds really good it fits good too. the only place ive noticed a difference so far is when im cruisin in overdrive its ALOT more responsive now. i was skeptical about this system because nobody seems to say anything about them on here. but im happy with it. also i was able to keep the spare and its a 17"

 

How much was it and where did you get it?

 

I've ran Dynomax products for several years now. They have all been Super Turbo Systems or mufflers. I have a Dynomax #17734 Turbo Muff on my current Truck.

I had a '95 F150 XL, Longbed, 4.9L I-6, with the Super Turbo dual system I purchased from Jeg's. I loved the power gains. I noticed torque in the low-end, and a little top-end power increase.

It didn't sound bad, either.
