Style: Base Product
Complete bolt on system sound quality of the system is 10/10 it’s loud. Only problem I had was had to replace the bolts for the exhaust tips with grade 8 steel bolts the original ones snapped I recommend washers if you have to replace them

    • Awesome Exhaust
Style: Base Product
Bought the system and installed it about 4 months ago on my 2009 4.6 3v f150. Since then I have enjoyed this exhaust system and recommend it to anyone who wants the loudest exhaust kit for the 09-14 f150s. Pros: - Exhaust is extremely deep and loud and I get compliments on it all the time. - Pipes look great (stainless steel and mandrel bent) and the black tips really set it off. - Drone is not terrible (granted I have 33' Nitto trail grapplers and always have the radio on which both cancel out the sound while cruising). - Install was not terrible, I rented a spot at a shop and was able to use a lift and their tools and with that it only took a few hours by myself. The main pipe, muffler, and passenger side went in easy; driver side was a little more difficult but not bad. Cons: - One of the pipe's hangers was bent upward which would not allow it to install correctly in the factory mount. - After installing everything, the driver side tip ended being about 4 inches inward which looked horrible. - While the clamps look like high quality, they do a horrible job at holding the exhaust. The driver side pipe would not hold at all and kept falling to point of almost dragging on the ground. Also after everything was installed the clamps made the exhaust look weird from the driver side and rear view. Since the clamps looked bad (also made the exhaust look like it could be disassembled by anyone in the street), exhaust was not even on each side, and having my driver's side pipe constantly hanging; I decided to go out and have an exhaust shop weld everything for me. If you get this system then I highly recommend you get it welded together. After being welded it has been the best exhaust system I've owned to date. It turn heads every time I drive my truck which I love and it looks amazing. ... show more

    • They truly mean outlaw exhaust
Style: Base Product
The media could not be loaded. It’s a great exhaust, have had it on my truck for a couple months now. I don’t drive where there is salt, but I am starting to see a couple of spots of rust. Pro: truck sounds like a mustang gt, not really any performance gains but that cold start though... like the tips, awesome feature on my blacked out truck. Quality material for the price. I paid about $475 on here when it was on sale once. Cons: not really that durable coating on the tips since I dropped it from 6 inches and scratched the coating down to the metal. You have to get this kit installed by a muffler shop and weld the pipes together. The clamps are garbage, ask me how I know... driving along after having it installed by my shop with no welds, hit a bump, pipe slides out and falls off. I take it right back to shop and weld that sucker on. Flowmaster, you need way better clamps if you want people not welding exhaust on. Personally, even if they had better clamps, I would still weld it to make sure there is no exhaust leaks. ... show more

THE SOUND IS AWESOME! I was not disappointed one bit. Flowmaster claimed this was their most aggressive system and they weren't lying. The tips look great and go well with my black paint job. It was very throaty and I received many compliments. Why not five stars? The instructions were a little confusing for this shade tree mechanic. Thank God for my neighbors across the street taking an interest in why I was laying under my truck cussing. On initial fit-up, the clamp with hanger for the inlet pipe/muffler inlet connection seemed to be in the wrong spot by like a foot. After cutting a foot off the inlet pipe and trying again, I discovered they assumed I knew to move the factory hanger and rubber boot which would have allowed the too long inlet pipe to fit perfectly. Luckily, the included extension pipe ( after cutting six inches off ) was adequate enough to restore my sanity. The only other issue was the pre-drilled hole in the hanger for the driver side rear was too small for the included mounting bolt. Drilled it out a little and was back in business. So far, I am not regretting my purchase one bit...but my neighborhood might not feel the same way. ... show more

    • This is not for everyone...
Style: Base Product
I am very satisfied with this exaust assembly. It was easy to install but it's better to have two people. I like how you can have to option to have the tips go straight out rear or 90°. It's is very auidible, considering it's flowmaster's aggressive series mufflers. DO NOT get this if you're just trying to get a little more rumble than your stock exaust. I've gotten almost 2mpg more and feel just a little more power. The down side is, drone going highway speeds (65-75mph). It doesn't bother me but I can see how it would annoy passengers. Keep in mind it IS loud, with a deep growl and iv received a lot of complements from people who have ridden in my truck. ... show more

    • HELL YEAH!
Style: Base Product
The media could not be loaded. It's a bit of a pain to get everything lined up and clamped together so it stays straight while it flexes against itself,..but overall pretty easy. 80ft of torque on the clamp bolts,.. no BS or things won't stay! Not the front flange bolts, those are like 25.

Very easy to install, had a little trouble getting the tips on the exhaust pipe but it was worth the extra effort. The system sounds, and looks great!

    • It is a super loud and deep exhaust
Style: Base Product
Arrived sooner then expected. It is a super loud and deep exhaust. I now have the loudest exhaust on the block. Wakes my neighbors up in the morning. I love it. Only bad thing is on the driver side exhaust keep sagging a little. However once I get it welded it won't sag any more. Great product worth every penny. ... show more
