Any tips on installing EPP Hot Pipes and EPP Dual Intake?

[Ish416]

I'm nearing the completion of mods for the SHO (just a HPFP and MAYBE turbos remaining). So far, I've installed colder plugs, thermostat, MSD coil packs, Powerstop brakes, solid mounts, 3 bar map, PPE down pipes, GH intercooler and just recently finished a suspension overhaul (new shocks, struts, HR Springs), on my SHO and installing these hot pipes and intake looks to be the biggest pain yet.

I haven't found any good videos or forum posts about installing the hot pipes or intakes. Anyone have any helpful tips, tricks or warnings on getting these things installed. Also, how long did the install of either of these take?

the S hose in the back S U C KS A S S and helps to have the down pipe off.

I could see that. Anything involving the back turbo is painful.

Removing the factory rear down pipe was horrible for me. Everything back there is so tight.

lot easier now once you have got the stock stuff out and the O2's have been out once.

The S pipe in back is the absolute worst, I reused the factory clamp as it was impossible for me to get the included clamp on. Mine is a PP car, for whatever reason, I had a 2019 non PP on the lift at work and it seemed to be a bit more open. High on the jackstands will be your friend for the S pipe. I have the Gen 2 (early Gen 2) and to get things to fit properly I had to move the box to the right about an inch and take 2" off the pipe at the filter end.

ya if your doing the cold side I too had to take off 2" of the bottom from the air cleaner to the front turbo and just skip putting the clamp on the turbo end of it as it is on the suckie side.

If you already did the downpipes then you know what your in for!

Make friends with a really small in stature person to work on anything in the back of the engine. One of my buddies is 5'5 and 105pounds, he almost fits perfect back there.

That's my problem, 6'3, 280 lbs, farm boy. I hate working on things because other people can reach into places with little to no issues. I have to use a ton of extensions and wobbles/swivels to get anywhere. I hate it.

Ha! you need a truck. My f150 is so much easier to access things than my old SHO

If you don't own an electric ratchet, get one before doing the install. A few of the clamps are down deep where you are bent over the car in an awkward position. The time saved tightening the clamps with an electric ratchet vs a hand ratchet is amazing. Know that putting in the air box is a giant PITA. I spent so long trying to get that POS to fit the first time that I ran it for a week with no box, just filter hanging in the open by itself, then the following weekend gave it another shot. It finally dropped in and fit, but I have no idea how it happened and am terrified to ever have to take it out again.

S pipe on rear turbo really isn't that bad in and of itself, what made it bad for me was the clamp for the stock one was not in a position where I could get a socket or a screwdriver on it to loosen. Depends on who put that clamp on last.....yours could be easy.

My biggest gripe was I did the intake and hot pipes at the same time and one came with metric clamps and the other came with standard clamps. I believe they have since changed them to be the same, but constantly switching sockets to loosen and tighten clamps purchased from the same place was beyond annoying.

Hot pipes if I had to do over again I would 100% just replace them with brand new stock ones. The intake I'd probably do again just for the cool noises it produces, and it does lower the wastegate duty cycle, but zero actual gain in 1/4 mile times at the track.

Thanks for the heads up on the airbox. I have access to a lift and just about every tool there is, so hopefully no issues there.

My purpose in doing this is because my car won't hold boost above 12 psi. It used to be around 17 psi. I've looked for boost leaks and everything thing else and found nothing. So I figured doing this would solve any piping issues and I would have all the best parts available for a stock turbo, stock fuel pump SHO. I also figured if I decide to step up to a fuel pump and turbos that I should be set and not have to worry about any piping issues.

Same thing happened to me! The stock air box is great until it’s not haha.

Check play in the turbos to make sure you don't have one going bad. Careful on the fender side of the air box it can rub on the wires.
