Hey everybody, I'm Justin with This is my detailed review of the cp-e Exhale Cold Side Intercooler piping with your choice of either HKS or Tial Blow-Off Valve fitting your 2015 and up EcoBoost Mustang. This kit from cp-e is going to be for the EcoBoost owners out there who are looking to upgrade the cheap plastic factory cold side piping, add that aftermarket Blow-Off Valve to get a little bit more sound, and put that Blow-Off Valve in the correct location on the cold side piping as opposed to the hot side piping where the factory Blow-Off Valve is located. I just want to be perfectly clear here about this part, guys. This is more about the upgraded materials, the addition of that aftermarket Blow-Off Valve and sound, as opposed to adding a performance part as you're really not going to see much of any gains with this kit. With that said, let's break it down a little further. The Exhale kit from cp-e is going to be a top shelf kit. You are going to be paying a little bit more for it up front, but you are getting some unique features so you do have to factor that into the price. First, let's start with some of the basics here. Again, you are upgrading that cheap plastic factory cold side piping with a nice piece of two and three-quarter inch mandrel bent aluminum finished off in your choice of either a satin black finish like I have on the table here, or you can also pick it up in a race red finish from the site. In addition to the upgraded intercooler piping you're also getting brand new four ply silicone couplers along with a few very nice T-bolt claims, but that's pretty much the basic stuff. As far as what makes this kit unique, well, here we go. Let's first start with the centerpiece of the kit according to the guys at cp-e. It's their MAP Tap system. This is going to tap into your factory intake manifold, deliver a very accurate boost reading, but more importantly, it's going to supply vacuum to either the HKS or Tial Blow-Off Valve as they are vacuum operated as opposed to the factory Blow-Off Valve, which is electronically controlled. Another unique feature with the Exhale kit from cp-e and something that I think is actually really cool is that they include two pre-welded eighth inch NPT bungs here on their cold side piping. You can use this in a number of different ways. Probably the most popular way would be to use it for a water meth setup for instance. You could also tap nitrous into these things or even use it for a mechanical style boost gauge if that's what you're looking for. Again, big thumbs up from me, and it's these small little things that cp-e typically throws in that separates their products from some of the other options here on the site. Earlier, I mentioned that cp-e does move the Blow-Off Valve location to the cold side piping here. Because of that, they do include a block off plate called their block plate, nice piece of CNC billet aluminum. Again, it's going to plug the hole left by your factory Blow-Off Valve located on the hot side piping. Why do that? Why move the Blow-Off Valve in the first place? Well, according to cp-e and most other popular opinions on the topic, you ideally want to have the Blow-Off Valve as close to the throttle body as possible to prevent any air flow reversal first but also to prevent a surge at the compressor to save your turbo and its bearings from excess abuse. Speaking of those Blow-Off Valves, I really do think that's going to be the biggest appeal when making the switch to this kit because everybody loves that Blow-Off Valve sound with the turbo car. By making the switch to an aftermarket Blow-Off Valve, which does vent to atmosphere as opposed to being recirculated like your factory Blow-Off Valve, you're really going to hear that noise whenever you shift or you do a big rev. You do have a couple of options with the cp-e kit here again when it comes to Blow-Off Valves. You can either go with the HKS Super Sequential, probably one of the most commonly used Blow-Off Valves in the turbo world, or you can go with my personal favorite the Tial Sport Q. This thing is available in a few different colors here at AM. By the way, should point out that if you are just interested in a Blow-Off Valve you can grab either one of these separately on the site here for a little cheaper than this kit. With that said, again, you are getting two totally different sounds from each Blow-Off Valve. To help you make your own decision when buying, we threw together a couple of sound clips for you. With the sound clips out of the way let's quickly touch on install. Really not looking at anything too crazy here guys, so for that an easy one out of three wrenches on my difficulty meter. You can access everything you need to through the engine bay. No need to jack the car up or anything like that. As far as tools, well, basic hand tools here, socket set. If you do go with the HKS option, make sure you have a pair of snap ring pliers on hand before getting started. Other than that, basic hand tools and about an hour from start to finish and you should be good to go. While you really aren't gaining a ton of performance from the Exhale kit from cp-e here, you are getting the benefit of running one of two most popular Blow-Off Valve options giving you that desirable sound. You're getting a noticeable improvement in quality materials over the factory part. Finally, you're getting those cp-e exclusives such as the MAP Tap system and the two-eighth inch NPT bungs, making this a very well rounded part for the money.

Allows for More Boost. The factory hot-side bypass valve (BPV) is fine for the daily commuter car, but if you are planning on increasing the boost and performance of your EcoBoost Mustang you are going to need to upgrade to a TiAL Sport Q Blow Off Valve (BOV) that is designed to safely handle the extra boost produced by aftermarket modifications. This TiAL Blow Off Valve is set to -8psi and can support up to 1,800hp. 

Vacuum Activated. Unlike the hot-side factory Ford bypass valve that is electronically controlled by the ECU, the TiAL Sport Q Blow Off Valve is mechanically operated by vacuum for consistent manifold pressure that helps keep your turbo spooled for better throttle response.

Quality Construction. Manufactured in the USA from CNC-machined 6061 aluminum alloy for strength and durability, this TiAL Sport Q BOV features a large 1.98" (50.5mm) valve with a high pressure Viton O-ring. The valve stem and guide are Teflon-lubricated, hard anodize-coated for superior wear resistance and the internal silicone diaphragm is reinforced with Nomex for long life.

Silver Anodized Finish. A TiAL Sport Q Blow Off Valve not only improves the performance of your 2015-2018 EcoBoost Mustang, but it also improves the under hood appearance with a bright silver anodized finish. This TiAl Sport BOV will give you the best of both worlds, style and performance.

Application. This TiAL Sport Q Blow Off Valve is designed for use on 2015 to 2018 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine, that have installed an aftermarket cold-side intercooler pipe with a BOV mounting flange.

Will thus work with the /mishimoto-intercooler-silver-polished kit. Thanks

  • The Tial Sport Q 8 PSI Blow Off Valve will work with any intercooler as long as the flange on the charge pipes utilize a flange that accepts v-band clamp style blow off valves.

    Not Very Happy

    I ordered this part for my husband for Christmas and was upset when I found out the part needed a tube that was not sold with it nor did it say anywhere on the website that it would need the part which is sold seperately. And now the part is discontinued. I called to speak with someone to see if they had any more in stock and the answer I get is that the website says no so no. Really annoyed me. I could look on the website just as easy. Not happy with American Muscle today.

    Get the 10PSI Spring

    This BOV is awesome but per Tial's spring pressure chart on their website my (and your) EB mustang requires a 10PSI spring. This has been discussed on many forums as well. Coupled with the CP-e charge pipes this makes for an awesome look under the hood with the loud distinguished BOV sound we all love and I highly recommend it! (with the right spring)

    Review from Tial Sport Q 8 PSI Blow Off Valve - Blue (15-17 EcoBoost)

    Tial sport Q

    The Tial sport Q blow of valve adds good looks and sounds. The unit is build beautifully with a perfect finish. I have the CP-E exhale cold side pipe in red. The Tial sport Q in blue added great contrast to my engine bay. Great quality, good looks and the potential for more power. What more could you want! Don't forget the great service from AmericanMuscle!
