I see the 15834 is no longer on the magnaflow web-site, what is the real difference from the 16614? I have a May 2004 5.4l s-crew XLT 4X4, thanks for any help you or anyone who knows can offer.

 

I am having a hell of a time getting the 15834, no-one in alaska carries it and shipping is retardedly expensive, I can get a 16614 here but am not sure of the level of modification required to install it and am not rolling in enough money to waste a 600.00 purchase, if it is as simple as moving a bracket I will do it, if it a routing or clearance issue then that makes it a whole new problem and I will spend the extra 185.00 for shipping since that is still cheaper than any of the quotes I have gotten to have an exhaust shop do it. If noone knows then that is fine, thanks for all the help.

 

Take a look at your driver's side rear wheel well. Looking at the frame (the outside portion)of the truck you'll notice a round tube cross member. Looks like a big round whole in the frame. Just to the rear of that there is a rectangular opening and then two smaller round wholes to the right (aft) and below. My 04' built Sept 03' has those wholes covered up with the trailer hitch support frame and a large bolt. If your truck has those openings visable I would think it fit with no problems. That rectangular whole is where you hang the rear hanger (both sides). I had to improvise with mine. It is a nice system.

 

Those kits were superceded to the 16612,16614,16616 applications

 

The 15834 kit comes with two different size pipes depending what cab you have. When i purchased tuner kit off of troyer perf. They sent me 15834 exhaust. So I got extra pipe
