The Supreme SP for the Ford Focus ST combines, classic GReddy styling and sound to boost power from the modern American EcoBoost powerplant. Large 76mm (3”) diameter mandrel piping is carefully routed beneath ST chassis through two inline, compact Supreme SP straight-through muffler sections. Dual 102mm (4”) GReddy double walled tips perfectly finish-off the system through the center exit bumper. Power tests have shown substantial increase in mid-range power and torque, with peak gains of 24whp and 11ft.lbs. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
I have EFR turbo and AUX fuel, I prior I had a MBRP exhaust great exhaust, cheaper then this one for sure but it did not last, needed multiple soldering to fix it, I got the aluminium version last 4 years. I needed a replacement, I went on YouTube listen to multiple exhaust and really like the sound of this one so I order it. I'm amazingly surprise on the sound, I love it not too loud when in low RPM, when I open up it is raging like a rally car, love it. Also call me crazy or lying about it but the gain I got from this compare to MBRP in torque and horse power and again the only proof I have is 3rd gear spinning tires and 4th now. Don't give me wrong i was able to spin my tires prior in 3rd but it never happen in 4th. I base myself on the feel and the traction control light. When I say feel it's like driving a different car. I put my foot to the floor and the boost goes up all the way in the red and hell comes out of that car now. Amazing, this review must sound childish or not real but I can affirm that I was not expecting any change from one exhaust to another at all, just the sound, I'm amazingly surprise and needed to share. I just love it.
Came super fast great quality and sounds amazing
I purchase this exhaust a few weeks ago and was told by Alan at Edge that it would take 10-15 business days to ship to my house. Knowing that this exhaust just came out and that it was in limited supply I thought this was a really good turnaround and was excited. The next day after purchasing I get an email saying it was shipped, and in 2 more days I received the exhaust. Excellent customer service from Edge and second to none in my opinion. Quality wise it's an excellent piece. All the welds were beautiful and you could tell its high quality even if you didn't know the specifications. It was also really well packaged. When I received it it was covered in layers of bubble wrap and foam to protect each exhaust piece. Seeing how well it was protected made me feel so much better about ordering from edge in the future, and I will continue to do so knowing that my products will come without incident. Installation was kind of a hassle, but only when it came to the over axle pipe. The heat shield had to be pushed in a little and the pipe needed to be finagled in order to get it to sit right. In my case when the whole exhaust was seated, the pipes sat a little to the right in the opening of the bumper. Not too noticeable but if you nit pick you can see it. Paired with a catless downpipe it still retains a deep tone and has mellowed out so that when cruising it is not very noticeable and then when you get on it it gets very loud but still retains a deep sound. Very impressed overall by quality of the exhaust, the sound it produces, and the customer service I received.
