What exactly is Borla?

Borla is an aftermarket exhaust brand known for performance systems made from T-304 stainless steel. The lineup covers mufflers, cat-back exhausts, axle-back exhausts, and exhaust tips. What separates the models is sound: Atak is the loud and aggressive family, S-Type is controlled but present, and Pro XS sits somewhere in the middle. I've ordered all three for customers, and the second question after price is always about sound.

One thing I tell dealers: don't promise a guaranteed horsepower number for a muffler alone. Axle-back systems are more about sound, weight, and tone than major power. Anyone who gives you a blanket dyno promise is overselling.

What's the muffler Borla Atak known for?

The Borla Atak muffler is the loudest option in the Borla lineup. It uses a straight-through-style core to open up airflow and let the engine's personality out. Borla still includes sound-canceling technology to help manage drone, but this is not the muffler for a customer who wants subtle. If a shop is installing one, I'd plan a sound check before the customer drives off, because surprise volume is the easiest way to get a return request.

Why does this matter for you? Because a customer who asked for something louder might not expect Atak loud. That's a ten-minute conversation that saves a week of back-and-forth.

Which Borla Chevy Camaro axle-back exhaust system should I order?

For a Camaro, the Borla axle-back exhaust system replaces the section from the rear axle to the exhaust tips while keeping the factory intermediate pipe. It doesn't change the catalytic converters or primary cats. That makes the install faster and keeps the cost lower than a full cat-back.

The key is fitment. A Camaro SS, LT, and ZL1 have different rear chassis layouts and tip spacing. Current generation and previous generation are not interchangeable, either. As of January 2025, Borla's website has fitment notes by trim and model year, and I still verify by VIN before putting a part number on an emergency order.

Here's a real one from March 2024: a shop called at 4 p.m. needing a Borla Chevy Camaro axle-back exhaust system for a Saturday install. Normal ground shipping was five days. We found it in stock at a distributor two states away, paid $180 in rush freight, and got it to the shop Friday morning. The upside was a happy customer; the risk was paying rush freight and still missing the window if the wrong part shipped. Real talk: the part number check stopped that from happening.

Do Mazda CX-50 roof rack cross bars require a vehicle-specific fit?

Yes. It's not a universal product, and that's where a lot of orders get delayed. The Mazda CX-50 has different roof styles: some models have side rails, and some have a bare roof with fixed mounting points. A cross bar kit for a side-rail car won't necessarily fit a bare-roof car.

This is the part that surprised me. The most delayed non-exhaust item in our shop last year wasn't a performance part. It was a set of Mazda CX-50 roof rack cross bars. The product was fine; the confusion was which roof configuration the customer had. Now our order form asks for a VIN or roof photo before we confirm cross bars. That one extra step reduced fitment returns dramatically in our internal order data.

Don't skip load rating and torque specs either. Even if the cross bars physically mount, using the wrong load rating on a customer's roof is a liability issue.

What are the best power multi tool uses in an exhaust shop?

An oscillating multi-tool is the quiet workhorse I didn't appreciate until I started watching techs use it. The best power multi tool uses in this shop are cutting rusted exhaust hangers, splitting old rubber isolators, trimming plastic undertrays, scraping gasket surfaces, and cutting through hardened bolts around the subframe where a reciprocating saw can't fit.

It won't be your primary tool for cutting an exhaust pipe. That's for a cutting wheel or pipe saw. But it saves real time on the small stuff that eats the clock during an install. Keep a carbide blade for rusty metal and a separate scraper blade for gasket removal. When an emergency Camaro axle-back install shows up, the last thing you need is a twenty-minute fight with a rusted hanger.

Can you over wax your car?

Yes. You can absolutely over wax a car. Too much wax leaves cloudy residue in trim seams, around badges, and in textured plastic. If you let wax dry too long before buffing, it becomes harder to remove. And rubbing the same panel over and over with pressure can put more stress on the clear coat than the wax is worth.

I've seen a quick wax after an exhaust install turn into an extra hour of cleanup because someone packed wax into the mirror housing and door handles. The answer is not always more product. It's applying a thin, even layer, working in small sections, and buffing while it's still easy to wipe off.

The same principle shows up in our ordering process: precision beats volume. One clean VIN match is worth two dozen guesses.

What's the question installers forget to ask before ordering?

The question isn't always which Borla part number. It's whether the kit includes all the hardware and mounting pieces. I've had expedited Borla orders arrive complete, and I've had a system arrive missing one tip clamp. Same for cross bars: if the mounting bracket is missing, you're not going anywhere. Check the box contents against the packing list before you schedule the install.

In my role coordinating rush orders, the efficient process is simple: VIN, trim level, and existing modifications up front. That one checklist cut our turnaround on emergency parts from days to hours. No amount of rush freight can fix a wrong part.
