I work at a Ford dealer, and I got traded in a 08 F150 5.4 with a 4" Banks cat back on it. Well we took it off and installed the stock one for the lot. Now, I sat it down next to a stock Eco exhaust we had taken off one of the lifted trucks we keep on lot, and it looked VERY close to same shape, and size. I put the truck up and it will in fact fit! It looks to be a diesel system, but I will have to have the mid pipe mated to our y-pipe. That is no problem with the resources I have, BUT with no resonator in the mid-pipe, is it going to be a drone machine?? Anyone have a 4" system without a resonator? Nothing better than free power

I imagine you can get it not to drone, Depending on the muffler that's on this system you took off is a different story... I say go for it!

It will still have that crappy v6 sound.....keepin my EB stock in the exhaust dept.

for free, what the heck!!! but like others have said, the EB sounds like azz with exhaust.

I agree about the sound, the Solo dual is the only one I kinda like. I want it for the performance. It is a full Banks system, so it has their muffler. I think if they can get it to clamp up to y-pipe, and not weld it, I will do it. That way I can pull at 1st sign of "azz" !!!!

Do it

ok I got it done today. The good: It for sure added seat of pants power, should get better as the computer adjusts. It sounds better, very mellow, and probably like they should sound from the factory. For whatever reason, the excess turbo noise from my SC seems to be gone??? The bad: they used the factory resonator and some of the smaller mid pipe. Also, maybe not as loud as I was hoping? I spoke to guy who installed it, and asked him if I was giving up power by not fabricating a larger mid pipe, and he said maybe peak HP, but turbo engines respond to smaller piping that dump into larger piping, as long as the large piping stays the same diameter all the way out the back.? Made it sound like the fast velocity dumping into a large pipe makes gains. I have not hooked up my data logger to watch boost ect, but I can't figure out why there is sooo much less turbo waste gate (if that is the proper term) noise is there. Maybe more back pressure forces the boost to build too fast? Any idea are welcome.

Exhaust cuts back pressure away turbo doesn't have too work as hard. That prolly why
