5” Exhaust Install

So I just installed a FLO~PRO 5” turbo back system this weekend.

I’d like to pass along some lessons learned.

1. Jack up your tranny and drop the crossmember. It’s not hard at all and makes things MUCH easier.

2. The v band clamp on the turbo is going to be tight as hell. I probably wasted 30 mins poking at it with a screwdriver.

If you touch each side with an air chisel, it pops right off. Literally a second a side!

3. Loose fit everything first. You need to be able to manipulate connections to make it fit right!

hope that saves someone else a bit of frustration!

@Nooch13 thank you for the tips. :awesome:

Great tips for sure! We appreciate you taking the time my friend.

Thanks for the advice. I have the same exhaust on order and hope it comes in so I can install it this weekend.

I did the whole 5" Flo Pro by myself last Saturday. Started by going through and unhooking all connectors first. Then i started from the back to the front and had no issue with the cross member. When there just the down pipe left you have lots of room to take it out. For taking the v-band off I just used a small screw driver with a prying end. Popped off like nothing. Remember there is a gasket in there that you might want to reuse. Everything gets a lot easier with the inner wheel well taken out. I left mine in for removing the stock down pipe but had to take it out to get the new down pipe the seat in there properly. With 2 people it is no problem. Slide the v-band onto the turbo elbow, then one person lines up the down pipe and the other slides the v-band on. Good luck!

Welcome to the family :welcome:

Just installed a FloPro 5" on my '17 as well. The clamp came off fairly easily with some light prying. Didn't have to remove the crossmember, plenty of room to move everything around. Now, the installation of the new down pipe is a different story! Did it alone so that probably didn't help. I have BDS double shock hoops in the front, so no removing the wheel well and the back of the turbo is too deep in the engine compartment to reach (at least for me). I fiddled around with that down pipe for like three hours before I got it installed!! It's tough to balance that heavy pipe, reach way up into a tight area (8" lift on 37's), make sure the gasket is on right and install and tighten the clamp. Talk about frustration! I finally got it on...I have to go to church on Sunday. ;-) FYI, I put a little grease on the gasket to hold it in place...that worked pretty well. Then there were issues with the exhaust moving around after install. I fixed that by making sure the band clamps were torqued to at least 50 lbs and added three or four 5/16" self-tapping hex head screws at the joints. Everything works great now, solid as a rock. Installed a muffler with mine, love the sound! Thinking about one of those AR-15 tips, but 300 bones...not sure if I can convince mama on that one. ;-)

Haha I struggled just like you the first time I did that down pipe! I did my wife's truck a year later and it went way smoother than the first time. I did not remove the cross member or lower trans....more work. Everything but the downpipe is a breeze.

LOL! Yeah...no problems the rest of the way back. It's too bad ya gotta do one first before you learn how to do one! :rolleyes:

Hello, I know this thread is old but wanted to say my tip.

I removed the passenger side wheel well and used a tiny bit of red gasket maker to hold the gasket while I added needle nose pliers to clamp them all together for a quick install.

Also if you have the clamp exhaust, I added exhaust tape in-between clamps to elimate the rattle.

Wished I’da thought of that when I did mine.

That downpipe was a royal pain in the begonias.

Thanks I'll be doing a 5" install myself this will help me out.

Love the 5".

Do you have to install a new down pipe when installing a 5 inch FLO~PRO?

If so does the exhaust usually come with a new down pipe?

Thanks in advance.

Bringing to life an old thread, but I did the 5” and had no problems.

Yes things were a PAIN, but I ended the install with just the axel dump.

Today I decided to add the tailpipe section.

Bought a tip and all for it.

After adding the tailpipe section it’s so close to my truck that it actually hits on start up and turn off.

Anyone else run into this and what was the fix?

I'm guessing its the tip that may be hitting your truck?

The only thing that I would know to do in this situation would be to try and bend the hangers on the tail pipe section in such a way that allowed for more clearance for the tailpipe, or get a smaller tip LOL.

I have 4 inch dual exhaust by FLO~PRO coming because with my Compound Turbo's pushes the downpipe to far back and it hits the firewall and the frame in front of the cross member.

I've tried everything to move it away but it always moves back so I'm going to 4 inch dual exit. :)

I'll post a video while it's being done.

No that is not the problem.

It’s just a standard 5” 90 down tip.

I finally got it figured out.

I feel you but try and do a 4 inch FLO~PRO Dual exhaust by yourself and they don't tell you that you have to criss cross the pipes for them to fit LOL.

I found it out after looking at it for a hour and a few Seltzer alcohol drinks LOL.

Sorry can't drink Beer I have gout from the Leukemia and hate it because I love Beer!

Take a Look at Dual Exhaust with 2 Black tips instead of one.

I had 5 inch dumping on the passenger side.

Now I have Duals and with the Tips it looks awesome.

2 black tips go from 4'' to 6" and my downpipe is still a 5" downpipe then I used a reducer to 4" and then 4" pipe to a quiet tone muffler then to the split.

Go see it yourself and please hit the like button and subscribe it helps me out alot!

I can't have 5" because it hits the cross member right after the downpipe.

No matter how I move the downpipe it hits because of the way the 2nd turbo sits so I had to go down to 4" to make it clear.
