PHRP H-pipe Review

[VaporDude]

I was asked to give a review of the PHRP GT500 H-pipe. This review is a non-bias review as I have no vested interest with PHRP. I was only asked to install the H-pipe and write a non-bias review of the sound of the H-pipe. The car only has the Ford Racing Performance Parts (FRPP) cold air induction and the FRPP KR mufflers.

Once I received the H-pipe from PHRP, I had it installed. It took the installer less than 30 minutes to install. I did have to purchase a set of exhaust clamps from Ford that is the same clamps as the ones that connect the mid-pipe to the factory X-pipe. You pull off the factory installed clamps and move them back onto the mid-pipe. This frees up the mid- pipe from the X-pipe. Hold the H-pipe up next to the X-pipe and put a mark on the exhaust pipe where the H-pipe ends. Cut the X-pipe off at the mark. Place the new clamps on to the exhaust pipe and slide them toward the front of the car a little. Place the H-pipe at the end of the exhaust pipe and slide the clamps on to the H-pipe making sure the clamp is centered over the cut. Pull the mid-pipe up to the H-pipe and center the clamps where mid-pipe and H-pipe meet. Tighten all clamps tight and you’re done.

Once I picked up the car and I started it up for the first time, I did notice a little deeper sound on cold startup. The car doesn’t have any of the raspy sound at all. Taking off out of the shop down the road, I did notice that the sound is even deeper when you push the throttle down hard. This is where you can really tell the difference between the H-pipe and the X-pipe. The more the RPM rose fast, the better the car sounds.

Deceleration is even more fun. With the RPMs up around 3500-4000 RPMs, and you let up off the gas to have the engine brake the car, you hear a nice deep gurgling sound and no popping. Down shift makes it more fun and the mufflers sound great as the RPMs lower.

Cruising along makes you want to use a lower gear to keep the RPMs higher so you can hear the exhaust better. Adding the H-pipe did not create any drone to the car. This is like music to my ears but it is not over whelming in the car. I don’t have any dyno-mat or any other type of sound deadening installed in the car.

I had to make a stop to take some measurements and I left the car running. I was at the rear of the car the whole time and it just sounded great sitting there idling. It has the nice deep idling sound to it. I didn’t have anyone with me to rev up the car while I was outside but with it just sitting there idling, you can tell this car has muscle.

What is my overall impression of the PHRP H-pipe? It helped make the car sound like it has a deeper sound to it. It did not create any drone and when you open it up, it just sounds mean. I think PHRP did a great job on this H-pipe and I do recommend it if you are looking for a deeper sounding exhaust system without the raspy sound.

Great review... I can't wait until I get my car back to get mine installed... I am supposed to bring my car to wes k in Naples to have it installed

Great right up. I Put the Ford Racing KR mufflers on today. There is a little popping on deceleration as you can hear in this sound clip. After I Install the H-pipe I will do another recording to see what the difference is.

I did not notice the poping in the cabin of the car, but the video recorder was attached to my lic. plate so it caught all the sound. It will be interesting to hear what the H-pipe does to the sound. I can't wait untill it gets here next week.

Here's my sound clip with just the mufflers.

at least someone was paying attention to the "before and after video/sound clips" requirement......

BTW Rob, what video camera is that you use? Seems to be good quality. I'm trying to find a cheap alternative for the ride to Shelbyfest. I wonder if I can post a 9 hour video documentary on one of these sites......

It's a Flip video. It's very small. Fits in a shirt pocket. They only hold 1/2 hour of stuff. I think the new ones are nicer. They are around100 bucks.

I'm going to upgrade to the new one. It's nicer and in HD.

I talked to Wes and he said that he was looking more for honest reviews. He said that he has tons of video comparisons of the before, after and a comparison with the actual KR. I am going to put my car next to a KR at Shelbyfest and do a video there if a KR shows up.

Nice write up. Another mod added to the list.

Great write up! Thanks! It's all we ask for is a honest review..good or bad. That would be really nice for you to see. We are lucky enough that we were able to do that. I actually thought ours sounded a little bit better but would like to see yours and others opinions.

There is nothing bad about this H pipe. I took the car to work the other day to help break in the KR mufflers. Everytime I step on the gas, I get a nice grin on my face with that great sound. When just cruising, you barely hear the exhaust sound. To me, this is the perfect setup for me. The nice deep growling sound when you downshift and let up off the gas. The nice deep note when you accellerate and the quiet sound when you are just cruising.

Awesome product.........

Thanks and I totally agree with you. I was like a kid in a candy store when my KR came off the trailer and I got in it for the first time. What started all this in the first place was a customer and myself. We were going crazy trying to get more of that OLD muscle car sounds. I think we drove Wes so crazy, then the KR showed up and we were in love with the sound. It's the closest to old school I've heard on a new model muscle car. And that was it, here we are.
