I have a 2000 with the rams horn y pipe i presume (based on forum research) there is nothing to be gained be swapping a stans or ebay y pipe ? anyone done the swap anyway ? diferent sound or any other change you noticed ? thanks in advance

 

YES, I did , on both my 2000 v-10's. I found an instant response in the bottom end torque. Even when I 1st started it, the torque rolled the front end a bit more. I was impressed. & yes , the tone changed, a bit more deeper but I got used to it quickly. I kept the stock exhaust & cat.
One other thing, I had a vibration or harmonic at 1900-2100 rpm under slight load, say up a gentle grade in 2nd or 3rd gear, & that dissappeared.
The 1st truck , I had the y-pipe made, my second, I used the Ebay y-pipe
& I think it was a cleaner job. No regrets with this mod at all..
I've added a 3.5" fresh air snorkle with a 5.4 airbox & the truck pulls my 35' 5th wheel very well.

Chris what brand is the 3.5 inch snorkle and what is the benefit of the 5.4 airbox? I've heard of the Zoodad mod but not the 5.4 airbox, thanks Sean

 

I used an F150 5.4 airbox , the front half only, it fits perfectly. The inlet is 3.5 " but the snorkle is still reduced, So I removed that, & added a 3.5" piece of exhaust pipe, & it will still get thru the factory opening by the rad. I used a hose clamp around the plastic to clamp onto the pipe, I stole the idea from the Banks airbox kit.
