BadlanzHpe, Inc. 7503 Goodman Drive, Des Moines, IA 50322

"Ive broken valves they do not hold up to high horsepower. Added a start for quick shipping."

"These cutouts are amazing. Took the muffler shop 20 minutes to install. As for the wiring (I bought the wireless kit, I strongly recommend it) I had it all done in less than 30 minutes. The ease of use and sound is awesome, if you're looking for dumps these are it."

"5/5 STARS! I was searching for electric cutouts for a while and read several reviews on BadlanzHPE, DMH, and QTP. I ended up adding the BadlanzHPE cutouts for my 1976 Corvette Stingray and I am very happy I did! Extremely fast shipping and very helpful and responsive on what parts I would need. 1 of the cutouts butterfly valve was stuck on arrival and BadlanzHPE immediately helped walk though how to diagnose and repair the issue step by step. Once we had exhausted all efforts, BadlanzHPE immediately shipped out a replacement part, free of charge. Couldn't recommend them enough!!"

"Been dealing with Charles for many years. Great guy! Occasionally (like every 1-2 years) have to send my 3" cutout back for warranty from normal wear and tear, but his are the best on the market. Before his, I had tried 3 other brand names and they kept breaking on me consistently. BadlanzHPE will always be my go to when it comes to exhaust cutouts. Great product! Great customer service as well. He is always responding to my emails within an hour."

"The quality of the products are top notch! Customer service is brilliant! I purchased two exhaust cut-outs, and they function flawlessly after a year of consistent use WITH NO LEAKS! Love this brand"
