Works perfectly! on exhaust and emissions

Easy to install and offers a noticeable reduction in overall volume and hum. The welds are excellent and actually rust free.

Pros
  • Pleasant to use
Cons
  • High price

Good price for spares

Exactly as written, great after welding. No difference in performance but eliminated the annoying hum coming from my straight pipe

Pros
  • Easy to use
Cons
  • Damaged

Reduces noise for spare parts

Excellent quality and reduces noise. I bought a 3 in/out variant and welded it to my turbocharged Acura Integra with a 3" turbocharged rear exhaust. My exhaust sounds perfect and there is no hum while driving.

Pros
  • An absolute legend
Cons
  • Not as good as it says

helped with back pressure

I installed these on my houseboat so I had a small area to work, they worked great, I covered the inside in paint thinking it would help hold it up? We'll see, damn if I get a year from them it's fine, I've got the back pressure I need for the torch

Pros
  • durable finish
Cons
  • fragile

Surprisingly good quality and perfect size

Very happy with it. They filled out a sizing specification which I couldn't find in the stores above and the build quality is pretty good. They even have a laser etch that ends at the inlet and a nice perfectly round slip fit joint. The welds were clearly machined, being even and smooth as they are. Bought to look like catalytic converters and reduce the harshness of an off-road exhaust system.

Pros
  • Good product for its price
Cons
  • Neutral
