I vote for Magnaflow. I had SIDO on my '05 scab, i like that system so much that when I traded it on an '07 Screw, I put the same kit on again.

Doesn't magnaflow make the mufflers for Roush?

Can you tell me specifically which muffler you've got?? Looking at their website I'm thinking about going with the 16616; 18" muffler w/ in front of rear wheel exit.

ROUSH Performance: ROUSH Ford F-150 Dual Side Exit Exhaust Kit (Off Road)

This is what I got.

Looks like my '04 takes a different kit than the '05-'09. My local muffler shop advertises Borland exhaust systems. I will go by there and see what they can do for me. They should be able to get me pretty close to the Roush pkg.

you can listen to the rousch on you tube. i vote for the rousch off road.

Nope, Borla.

Did I say "Borland" :-huh
Meant Borla.8D

You should go with ROUSH. You can't can't go wrong with the off-road versions of the ROUSH cat back exhaust. I personally like the looks of the Dual side exit kit. If you decide to go with a ROUSH kit contact Mike Roth at Woodhouse Ford mroth@woodhouse.com
You will be very pleased with the sound of the ROUSH exhaust. I had a Bassani SISO kit before I decided to order the ROUSH kit. Although Bassani makes a awesome product, the sound wasn't quite what I expected. Which reminds me, is there anyone in Southern Cali who would be interested in a used Bassani SISO catback system? I have the stainless version and it was on my truck for less than 6,000 miles, includes brand new 4" tip.

Installed Borla on F150 and Cobra...great sound...love it. Highly recommend!!

This is the closest I could find to the sound my F-150 makes. The only difference is the side exit in front of the rear passenger wheel. The cold starts sound good but it really sounds great when driving and it is under load. the revs when sitting still pale in comparison when you take off from a stop and when you nail it on the roll. I really love it. To me it is the best sounding F-150 I have heard, and not just because it is mine at all.:-drink

While the Roush kit is made by Borla, you won't find a Borla system that's exactly the same. The Roush kit routes the pipes differently and they are a different size.

I'll throw another vote in there for Magnaflow. I've got one on my truck and it sounds great.

Borla IMO. Sounds MUCH better than my friend's Magnaflow on his F150 and it's almost as loud.

It won't win you any volume contests but it sounds damn good and apparently it's considered "loud" by a few girls that can hear it from outside the cab when I pull away. I wouldn't necessarily say that though lol.

Checked out three muffler places today, all three said they could order me the Magnafolw, but two recommended Flowmasters. I got the feeling that they didn’t think there was any difference between the two. In fact one place told me that Flowmaster builds a generic version of their muffler for other companies. Midas has a deal going right now for Flow master dual out system for $299, for the 40 series, and $349 for the 50 series. I’m sure that Roush, Borland, Bansini… are probably much better mufflers, but how much better? I’ve gotten a lot of recommends for Magnaflow, but is this the old Ford / Chevy debate only between Mag / Flow?? I don’t want an overly loud system, but don’t want to drive away feeling like I didn’t get enough bang for my bucks. Flowmaster has an ‘American Thunder Muscle Truck, dual out same side system’ that looks like what I’m wanting, and it looks like I can get it, plus installation for $300.
