Our story

Straight Talk, Solid Welds

We're a Fontana muffler and exhaust shop built on doing the work right and treating customers fairly. Whether it's a muffler delete, exhaust tip installation, or a full custom exhaust setup, we take the time to get every weld clean and every fit exact — no rushed jobs, no shortcuts.

Our customers come in with everything from daily drivers to project cars, and we've handled it all: Honda Accords, BMW e30s, and plenty in between. We'll walk you through pricing before you're even in the bay, so there are no surprises when the work is done.

At the end of the day, we want you back in your car sounding — and looking — exactly how you pictured it.

  • Custom exhaust fabrication & welding
  • Upfront price estimates before work begins
  • Experience across import & domestic vehicles
  • Friendly, detail-focused service

What customers say

“Absolutely perfect job! They even helped me install the diffuser on my 2018 Honda Accord to make sure the exhaust tips are installed perfectly. They took their time, made sure everything was welded and installed perfectly, and offered a great price. For exhaust tips installation and muffler delete, they charged me $220.”

Joshua Snyder

“Good and quick service, the price was fair and he payed good attention to detail. The welds came out great and I was very happy with the placement. Friendly customer service as well.”

Eduardo Cabrera

“Solid welds, and provided great options for my e30. First time ever visiting. Highly recommend doing business with them.”
