Quality piece

Installed it the same day I received it. Took about an hour sounds great

Awesome Customer Service

Although I'm enjoying the part I received. I'm going to give an overview of my order. So apparently this item I ordered came with the STI flange and not the WRX model I was meant to get. I let them know of my findings and they were quick in processing the RMA, but me being so impatient decided to order the WRX adapter they carry here separately and I'd just swap out the flanges myself. After I let them know of the situation that I'd rather just keep the BOV and ordered the adapter they immediately honored the adapter and shipped it to me via 2 day and of course arrived on the 2nd day. Although I was not content due to the fact that I was given the wrong part. The 5 stars goes to the way they handled the situation and shipped me out a wrx flange. Would be happy to do business again as I see these guys as even though mistakes happen they honor the customer's concerns. Definitely recommend this company to anyone, customer service will always be top priority in my book and they have it. Loving the bov btw.

Fixed my wideband gauge issues!

Wideband was reading full lean. After swapping it out with the new sensor it worked great again. Thank you MAP!

Great Price and delivery

Came in on time and good condition. Can't beat the price! Looking forward to buying more parts in the future.

Great product

Everything works great its just what i needed the only thing bad was it shipped threw fed-ex so i got everything 5 days late

So many things extra.

Walked into map and spoke to the sales department about a few parts i was looking for and walked out with one for my Focus ST. Awesome place awesome product just one of the best flash tuners i have used!


I was extremely pleased with the end result of this axle back! Before I get into the nitty gritty, I want to thank works immensely for packaging the AB very well and also including a neat little box with a gasket replacement, instructions, as well as a few gifts being a keychain you can proudly place on your keys stating works as well as a bumper cover replacement that was a pretty basic black for the most part but boasted the works logo subtly which I found pleasing because I didn't quite like the bumper cover from the dealer. Now for the preparation and installation, it couldn't have been more cut and dry. Remove two bolts, jointing the front pipe to the muffler. Then pop out the stock muffler off of 4 rubber mounts. It took me a minute in particular, because the two bolts I was working with had seen some time and were a tad rusted. But I managed to get them off and crank them back on. Putting on the Works AB was a breeze, after prying off the stock one. It couldn't have been easier. Prop it on the four rubber mounts, Works makes it extremely easy because there mounting solution is actually factory fitted. Getting it into place, replacing the gasket, and tightening the bolts. I suggest Vaseline for the four mounting points on the AB as it slides right into the four rubber mounts with ease, making it much less of a hassle. After all is said and done, the car is transformed significantly! Its sound amplitude is way larger than stock, but still keeping a nice and subtle idle. When applying the gas, you can actually appreciate the cars lack of power due to the end result in sound. It's very refine but not to aggressive, just a tad louder. The best part about this axle back is that it so desperately wants to crackle and pop when engine braking or on a down shift. If upshifting quickly, it creates this valve like muffle and its most certainly ear candy. I love what this exhaust has done to my car and can't wait to hear what it has to offer once everything is said and done with the exhaust system. Thank you Maperformance for shipping this item so timely! You most certainly have my business for many mods to come!

PART# GSC 7010S2

Purchased GSC S2 with MAPerformance recommended bundle containing retainers and springs. Great price and fast delivery. Great bundle option for budget build


Maperformance put together a great kit for anyone planning on using e85 or upgrading the fuel for more power.

Perrin throttle pedal spacer

Awesome product. Does just as describe and makes driving more enjoyable now that I can properly heel toe. Only giving four star due to the fact that you have to shave off part of a stud. Other than having to do that, it’s a straight forward job.

Beautiful Upgrade

Excellent replacement for the junky old OEM one. Plus it dresses up the engine bay a bit.


Exactly what I needed! Fast shipping!

Map came through once again.

Everything I needed!

Fast shipping! And everything I needed to get the job done.

Gets the job done

OEM upper house started leaking, bought this kit and replaced all of the hoses. It’d be nice to have the OEM style clamps as opposed to the screw righting ones this comes with, but the hoses are much thicker than OEM. Black looks fresh and simple.
1k miles on them and no leaks or issues yet.

Great product & service

Product came very fast , lowered car exactly how I wanted it . Will highly recommended

Green Filter Air Intake

10/10 if you want to hear the turbo spool ! The wrinkle black blends well with my engine bay .

KTuner 1.2 on my Gen 10 Civic Si

The flash process took about 20 minutes and the KTuner website instructions were easy to follow. There several how-to videos on YouTube as well. Just make sure your laptop power manager is set up right per the video instructions,

I chose the stock/23psi dual map and it really made a big difference in the car, particularly in the mid-range roll on. I commute over the Santa Cruz mountains where you will find lots of semis, buses and other rolling roadblocks on the climb. Having this extra torque and power down low was the main reason I bought the kit. I am very happy with the results. The car is really fun and very quick.

I did see a 10-15% reduction in MPG, probably because it’s just so fun to stand on it. Also, I’m not totally convinced The stock, non-sport mode map, is exactly standard. But, I’ll go with it.

Price point!

This is a great mod for the price!

2150cc fc !!

Simple amazing ! Thank you for taking my evo to the next level

Amazing coilovers!
