In the words of our drivers:

The crew at Dundon are Customer service oriented and offer the best parts available to their customers. They work had on developing new products and have the ability to think outside of the box (stuffing a 4.0 GT3 motor into a boxster) the do everything from building custom exhaust, motors, developing new parts, dyno tuning, to general maintenance. Their exhaust systems are the best exhaust anyone can buy. My full exhaust system added 40whp on my GT3. I truly appreciate the passion the team has towards Porsche. I have and will continue to recommend their products.

In the words of our drivers:

Let me start by saying how great the company is to deal with. I was texting Jamie on a Sunday...a Sunday...he answered all of my questions prior to placing my order. They also have a 30 day money back trial, Where does that happen? I'll tell you, nowhere! The system arrived after. Read more about review stating I just installed my full

a few week wait which was totally worth it. The systems are made in Washington State by hand, one at a time by real craftsman and it shows.

Do not hesitate to buy from Dundon. You may be able to save a few bucks with one of the other systems but if you are considering changing the exhaust on your super car, you really should be shopping for the best not pinching a penny and Dundon delivers.

In the words of our drivers:

Elite knowledge and experience. Everything the dealership missed or couldn't answer, Dundon did. Regardless of how far it is from where you live, it's worth the trip if you care about your car's health and longevity.
