I believe they will fit, I see no reason why they wouldn't.

BTW there are only 2 brands of long tubes that fit the coyote 5.0 in 2011 up 150's. They are

and

Why are those primaries so big?

Headers should fit regardless, exhaust after the headers will be the issue.

 

thanks and do you know witch headers is the best?

 

I plan on using the stainless works headers on mine when I have the spare coin to spend. I do know that SW uses T-304 stainless for all their exhaust products IDK what grade of stainless american racing headers uses. There are two grades of stainless used in exhausts, T-304 and T-409, the 304 is better and more expensive.

The biggest reason I'm going with SW is they are local to me, and I'm all about supporting a local business if I can.

 

ok fine but on the sw site the spec talk about 145 wheelbase truck for the headers... i dont inow why because everybody tell me the catback is only the exhaust pieces specific too the wheelbase configuration.. .

 

Every 5.0 truck should be exactly the same from front bumper through at least part of the cab, if not further back. I don't know why they say you need xx wheelbase for just the headers, but I know why you would be concerned. You may have to go custom after, no kit, after the headers or mid pipe, but the headers themselves should go on fine. I think if these kits come with the mid pipe right after the collectors, the mounting points for mid pipe are what are wheelbase specific.

 

i find the headers all the same for all truck so it a go but the catback is more spesific

 

Speaking from personal experience, I think you should get the headers, then do custom true-duals with an X pipe done for you versus buying a catback. I have OBX headers, OBX Y pipe, 8" of factory pipe, then Roush (Borla) catback. I was lucky enough to have everything go together pretty well, and even then there was a good amount of guess work wondering if it would fit or not. I'm lucky I cut up my factory exhaust in a way that I could re-use that 8" piece. For you, especially because you don't have any "out of the box" kits that we have reason to believe will fit without any issues/modifications, I'd just get a shop to do everything from the headers back (or maybe from another foot or so down if the headers come with some pipe after the collectors). I just think an X sounds better and there aren't any "kits" for that, not for my 2006 at least. And trying to make stuff fit together on your short-frame truck may work out quite well, or just lead to a bunch of headaches. I regret not having true duals with an H or X pipe from the get-go, but I'm unwilling to chop up my 304 stainless exhaust to get it.

I'm curious as to where your frame has been shortened. The reg cab 8 foot bed, scab 6.5 ft bed, and screw 5.5 ft bed all have the exact same frame, and I'm led to think the exact same mounting points for all the exhaust hangers.
