......on a 2v 5.4? I've been looking at catbacks for my 99. I realize that most people on here love Magnaflow, but I just hate to spend the $$ for it. I've looked on Summit Racing, and the Dynomax cb is $259, as opposed to the $489 for Magnaflow. Heck, for the cost of the Magnaflow, I could get the Dynomax and a K&N FIPK.
So does anybody run the Dynomax Super turbo SISO? What do you think of it?

Thanks.

 

You get what you pay for.

 

I did have one from 2001-2005, but it rotted away It was a good system, not really loud but big block sounding. I liked it alot, just the winters around here ate through it so now I went stainless. These were quiet at cruising, but WOT, it was alot nicer. I would buy it. Dynomax's have good flow too, not like you'd feel it, just probably make it sound better at higher revs.

 

Did you notice any increase in mpg? That's one of my main concerns. I'm not too worried about it rotting away. I've been running an aluminized h pipe on my Cobra for 4-5 years now with no problems out of it. Our winters aren't that bad. I just want to get a better tone, and maybe pick up a bit of fuel mileage in the process.

 

Try A Dynomax race mag they sound really good on every truck I have ever heard them on. They also flow better then magnaflow. They have to different styles a round and an oval the round is louder but the oval has a nice mellow rumble to it. I have had dynomax on all of my trucks and my friends also run dynomax race mags on Fords chevys and dodges never had any problems. Good luck
