This is going to be short and to the point, where it should be very detailed and offer suggestions and installation tips for those of you who have ordered the CP-E Cat-Back Exhaust System.
I installed the system, all by myself, no help whatsoever, on Sunday the 14th, and have put some 250 miles on my CX-7 since then. I of course reset the PCM during the installation, which took me about 3 hours total time elapsed, and the CX-7 is really coming to life right about now.
I don't have a lot of time to go into it tonight, as I'm getting ready for my vacation which begins on the 21st through the 29th, but having received and installed the
very 1st retail unit from CP-E, let me just say that the performance increase is tremendous, something you can really feel after the PCM adjusts to the Mods you've done, as I've done! It seems like the comments like "turbo motors are very sensitive to changes in the exhaust system" are particularly true with our CX-7's...after PCM resetting and breaking in the system, the 2.3L Mazda DISI turbo motor just starts "singing a different song" at any throttle setting with this new exhaust system!
As I wrote above, getting rid of the stock muffler system is the best kept secret yet as far as letting the CX-7 turbo motor breathe, and breathe most excellently with the CP-E system. With my CX-7, especially having the other Mods of the CAI, the TMIC, and the BOV replacements, I'm noticing a huge difference in performance, something you can really feel, and the sound of the cat-back system is just fantastic!
After I return from my vacation I'll be able to devote the necessary time and energy to putting together a web page devoted to the CP-E Cat-Back Exhaust System, but just let me say a couple things about it. It comes packed in a very professional HD 60" x 40" x20" box (approximate dimensions), and it's extensively protected inside the shipping container with heavy packing paper, and lots of bubble-wrap and plastic air bladders. So there should be no worries about getting your unit damaged whatsoever: CP-E really takes great pains to make certain that the system arrives in perfect condition via FedEx Ground Shipping.
You're not going to "knock out this installation" in 40 minutes as Shadow1 said he could do, unless you have access to a rack for your CX-7, hanger pliers (I did without them, and used other techniques to deal with the hangers), and several people to help do the necessary lifting and fitment of the system.
It is a little more involved than just swapping out the stock muffler for the CP-E system, but even 1 person can pull off the installation with the right tools, a little ingenuity, and some common sense in a couple of hours.
That's about all I want to write at this time, as I can see I've already done more than I wanted to. This CP-E system is an exciting Mod to do to a CX-7, especially one with other Mods already in place. I'm getting a real, honest feeling for 280-290 SAE HP at the crank with my CX-7's Mods now, and even more torque than that. How much I really don't know nor can I prove it, but my CX-7 is just fast across all the RPM's now. I have to thank CP-E so very much for getting this 1st system out to me last week, and I promise to give a thorough report about installing it when I return from vacation.
Get one of these systems for yourselves, as it's such an XLNT Mod to do for a major HP and torque increase in the CX-7.
Kindest regards,
