Downpipe construction and quality was top notch. Instructions are a little difficult to read due to the all gray print style on the pictures but they’re passable with the help of YouTube here and there. My catback fits better now with this downpipe than it did with the OEM! Doesn’t change the tone of the car but the volume is a bit higher and the pops are more aggressive plus lots more turbo noises than before :D. The butt dyno is also very happy - very noticeable mid range gains. Highly recommend and will continue to support CPE
The product itself fits well and functions as it should but I never received the extra bung plug for the third extra Insert on the pipe. It showed on my paper it should have arrived with the first package but didn’t.
It was a tight fit and I had to make a few modifications to the install instructions for a better overall experience. First they only include a black and white instruction sheet and I had to ask them to send me a color PDF. Second I did not use their bracket for the ambient air temp sensor. Instead I cut the front grille overlay in half basically removing the section that covered the front of the stock intercooler. I left the factory insert for the AC condenser/radiator which holds the sensor. Third, I watched a YouTube video where the installer mentioned drilling open the hole in the factory plastic bracket where the factory intercooler hook goes over. This allows the included bolt to fit better. This was a huge time saver. Lastly I cleaned the charge hoses really well with brake cleaner and upgraded to some constant tension liner clamps and torqued them to 55-65 in-lb. I didn’t have any issues with the hoses popping off.
I did extensive cataloging and with the stock IC the charge temp would rise 60-100F over ambient. With the CP-E it only goes 10F over ambient.
For tuning you don’t touch the intercooler volume or high pressure drop table for the best results. When i tweaked the pressure drop table it would cause drivability issues. What I did instead was raise the max boost limit since the CP-E could reject all of that heat.
WARNING: 2016 models . Product is great quality BUT. It's just short . It does fit . But just barely. From the turbo to the cuppling I got like less than half an inch connected. I honestly think its gonna pop off but it's been good so far . Hoping the company makes it a good 2 inches longer.
