This amazing muffler

This muffler sounds amazing, was easily installed at my local muffler shop and has really changed the sound of my car. The Pro xs' mufflers produce a low hum at idle and spring to life when you step on them.

Read all reviews. Few said they were "loud ".

What I don't like is that the exhaust is almost too loud for a daily driver when starting or flattening the throttle (not mush), but fine for MSRA or NSRA fairground driving. I like that the exhaust is quiet on the highway. This is a straight muffler so be aware of that. I installed two on a 1946 Ford coupe with a stock Chevy 350 engine with cast manifolds and TPI. I'm 73, maybe that's me.

Pros
  • Muffler
Cons
  • Some troubles

I love these Borla mufflers

I love these Borla mufflers. They start out a little louder than the factory mufflers and die off within a minute on factory mufflers. They don't get much louder in normal driving, but once you get behind the wheel they really come alive with a clear, non-cloying sound. I used 40659 on my old 4 cylinder Elantra and it was great, my car didn't even sound like a herbivore. When it came time to upgrade my exhaust on my LF Sonata, only one Borla came to mind. These mufflers are loud when they're…
