Im absolutely thrilled with their customer service. Jacob and his team did an outstanding job rebuilding my engine in less than two weeks and now my engine sounds like a clock. Im definitely working with them in near future and they got me as a customer for life.

This shop is amazing I just wanna say thank you guys for putting my nitras and doing my rear in my car is a totally different car

They did an amazing job building my motor, and getting it tuned on the dyno.

Arrived no manager on duty workers couldnt even write up work order cause manager had keys to the office

Everyone I met at the shop was very friendly, knowledgeable and helpful. I would recommend these guys to anyone. Love their new location in Menomonee Falls as well! Very spacious and well kept.

Brought my car in for a dyno run and they made it easy and simple for me. They were ready for me and had the car strapped down in 15 minutes and took plenty of time to make sure everything was done correctly. Very personal and professional. Great guys that I would highly recommend to anyone!

Competitive pricing on service and parts! great knowledge base

After struggling to find a place I trusted to point me in the right direction towards the perfect performance parts for my car, I had stumbled upon Xtreme Autoworks, Facebook page, conveniently enough it was located near me in Butler Wisconsin, their lead guy Jacob provided me with very well detailed information on the best parts on the market in order to utilize the platform I was modifying, on top of the utmost professional service my parts arrived even faster than I could’ve hoped for. I can’t wait to get them installed and enjoy my car this spring, I will most definitely return to Xtreme Autoworks for any of my future purchases.

Everything that was supposed to happen did. In the said time, for a great deal.P.S.Even got some free advice.

Great quick service for my camaro. They a did custom exhaust for a fair price amd installed a few other performance parts. Great work i look forward to bringing my truck in for a rough country lift soon!

They were awesome to deal with got my muffler and catalytic converter replaced was done in a couple hours and very reasonably priced ! Thanks guys!

Great quality work. Good lead times.

Got my part over night with free shipping. If you’re looking for friendly, complete service I would recommend this place.

Great job on my auto nick
