What Exhaust do you run?

Stock w/turndowns. A $40 mod from the boys at Midas.

Dual 3" Spintech with an X Pipe

That is one SICK looking exhaust! How does it sound? Drone? Video? I NEED MORE INFO...lol


I forgot to post what my Raptor has. The previous owner installed a Magnaflow catback only exiting behind the rear tire. It is what I consider very tame under normal throttle but according to my son after our trip home with it from picking it up in Illinois, it sounds BAD@RS at WOT. I do have plans to change it at some point to test some different set ups, but I am partial to the turndown style of exhaust myself so the MBRP turndown is more than likely my next choice.

I bet if you look really close you will find witness marks on the pipe where the spring is hitting it.. That is whats braking the clamps/brackets .. I do agree with you they are smallish but its the hits the pipe is taking.....If you have these marks in your frame from the spring then you pipes is taking a hit also..

Mine don't go under the spring, they are straight out the back of the truck.

Mine don't go under the spring, they are straight out the back of the truck.

I would guess in your case, since they go straight out the back, instead of the springs hitting them and braking the clamps, it would be the top of the axle housing hitting them on both sides. Did you have any marks on the top of the axle housing? Bottom of the pipes in the top of the bend somewhere? Honestly, I can't imagine that this is only a SW issue. All aftermarket kits are designed with the stock trucks being used moderately off road in mind and because of that, no matter what kit you put on your truck, if it exits anywhere behind the rear axle at all, the travel of the rear suspension is going to beat the pipes enough to abuse the hangers and ultimately break welds at the muffler, etc. Especially in your case where you seem to take your truck to it's limits when off road.

SW did redesign the hangers about a year or so ago, but I wouldn't imagine there is any way to account for every possible off road extreme when designing the placement of the rear pipes to be able to avoid contact with the pipes for those that take the trucks to their limits off road. That only way that I foresee avoiding the same situation with any brand exhaust is to install a kit that exits somewhere in front of the rear end like the MBRP turndown or the SW lightning side exit.

ALTHOUGH, I could be mistaken on this. I have never taken a truck to that extreme and I am only trying to picture in my head exactly what is happening in the rear of the truck when jumping, etc. If I am completely wrong, please let me know because I would like to fully understand before I decide on which SW catback is going on my Raptor.

From looking at the pictures of the hangers on the SW as provided, I do believe they could be fully welded instead of tack welded in place. It also may firm things up to also tack weld the clamps during installation.

One last thing and I'll shut up. I am NOT defending SW in any way. I am only attempting to figure out if there actually IS a real way to fix the issue, whether it is in fact SW related and not pipe over axle/spring related, hanger weld insufficiency related, etc. It could go a long way toward making sure that other members AND exhaust companies as a whole better understand the systems they choose/build for the given application and possible use by the end user.

I don't have SW's but I hope to get them and I wanted to see the stats

How old is the system you have? When you get a chance to get under there and take pics please forward them to me. I am very interested in finding the source of the issue whether it be weak clamps, pipe position as designed, etc. Whatever the cause, I am wondering if the other styles of SW have similar issues.

My system is a year old. Did not get to use it much last year, started more with the SnoBall 500 this year.
Below are the first hanger issue. This snapped at a weak point by the pipe.




Then this last weekend the stainless light weight hanger snapped at this small part that bolts to the spring hanger. And the only flexibility for all of this is the small blue grommet.


Below is where this is supposed to be located.


You can see on the above picture I welded a support in the bottom hanger part that bolts to the pipe, and this seems to have fixed the problem.

The problem is these parts are designed for a street car. I have a video shooting on the back I will post shortly.

Pipes are not hitting the axle, just lots of vibration.
