Hello !

I am wanting to upgrade my exhaust on my 1997 F-350 DRW to a 4" turbo-back system. I do have a Pacbrake installed. I noticed during my research that they sell an adapter for a 4" exhaust system. Have any of you done an install with a Pacbrake? Got any tips to share? FWIW I have ordered the adapters (2) and a Diamond Eye 4" turbo-back system. Thanks in advance for any info you can share!!

Note: Sorry if this has been addressed somewhere here, I attempted a search but may not have been using the correct terms or spelling.

 

My neighbour did a system like this on his. I think he did an mbrp system with the brake. He says it works very well.

 

Where does the pac-brake go in the exhaust system?

 

At the bottom of the dp

 

So what diameter is the pack brk ?

 

I'm pretty sure it's 4". I'd have to look though

 

Hey sorry I have taken so long to get back to you. Luckily, the previous (first) owner of this truck saved EVERYTHING including the manual, and instructions from the dealership where he had the Pacbrake installed. It is a model C-15000 Exhaust Retarder

It mounts directly to the back of the turbo, and is vacuum operated. I am still trying to figure out the 3 position switch in the cab but it seems the "up" position applies the brake manually, the middle applies the brake any time you let off the throttle and "down" is like a cold weather warm up position? Sorry getting side tracked on operation of this thing...... it's still new to me.

I'm not sure what size the outlet is on this, whatever size stock exhaust is I'm guessing? now looking at this, it seems different from Pacbrake's current offerings which are air actuated and don't appear to mount directly to the turbo.

EDIT: If that link to the install manual does not show enough, I can try and snap some pics in the daylight to better illustrate. The more I look at it the less I think I'll need those adapters.....may need one but defintely not 2. Those must be for the newer PXRB models?

 

By the looks of the picture it goes Right in place of the Stock EBPV and does NOT effect the DP at all. SO if you get ANY downpipe for an OBS you will be fine

 

Kinda what I am thinking now too! I'll keep you guys updated once I get the kit and start installing

 

Everything has come in! Just need a day of to check it all out - I'm off this coming Monday thru Thursday, so I'll get it all checked out then!

 

Got the exhaust box opened, and was able to compare parts/pieces tonight. It looks like the new Diamond Eye DP will connect right to the back of the PacBrake without any modifications. Can't wait to get this stuff installed!
