Disappointing: Low-Quality Exhaust Caps

Thanks to my knowledge gained in practice as an automotive enthusiast, I can safely say that these bypass caps are a waste of money. The thin material used in the construction of these caps makes them prone to warping and cracking under high temperatures, thereby defeating their purpose of reducing emissions. The only positive thing I can say is that they are relatively easy to install. Save yourself the hassle and opt for a higher-quality replacement part instead.

Pros
  • Convenient and easy to use.
Cons
  • May cause damage if not used correctly.

Buy them if you want to plug a big hole.

I pushed a 3/8" cap down the 1/2" outlet and it snapped causing a significant vacuum leak. Do not do that. Buy the right thing. This is good quality. Buy it.

Pros
  • Provides a snug fit to prevent vacuum leaks
Cons
  • Easily repairable

Revainrating 4 out of 5

Arrived quickly and half satisfied.

I expected them to fit the back of my Holley carburetor. It was loose and falling off, one was actually smaller in diameter (not much) than the other. I'm pretty sure the port needs a 1/2 cap, but I'm not sure, so 4 out of 5. Arrived quickly, half happy.

Pros
  • Made from durable, heat resistant vinyl
Cons
  • Nothing
