Which is better test pipe or high flow cat?
High flow cat will cost more and have a little less power and smell better. Test pipe will be cheap on ebay, have more power and stink for people right behind you. I went the test pipe route and made the car louder and kept the stock exhaust. Much cheaper that way.
Are test pipes louder than high flow cats?
do the high flow cat. test pipes just make your exhaust louder and more raspy. not worth the 1-2hp you might gain over a HF cat. plus you’re not polluted.
Does test pipe add horsepower?
Re: Test Pipe Gains (99AccordTurbo) There’s a bunch of downsides to a straight pipe, and the hp gains are minimal over a cat. With a straight pipe, it’ll sound bad, smell bad, and make it troublesome when smog time comes or when you get pulled over. For purely horsepower, a test pipe is worth it.
Do test pipes add horsepower G35?
ISR Performance G35 Test Pipes These test pipes are made with high-quality stainless steel and come with bolts, gaskets and 02 sensor adapter extensions. Their straight through design will help add the maximum amount of horsepower and torque to your VQ, especially when paired with the ISR Y-pipe and exhaust!
How much HP do you gain from test pipes?
I’ve heard you can gain around 25-30 HP with a test pipe and 10-15 HP with a high flow catalytic converter.
Why do you need a cat test pipe?
For turbocharged cars, this results in less back pressure and better flow for the turbine. Test pipes or, cat delete pipes, or straight pipes, do not contain a catalytic converter. The performance of your vehicle greatly increases with the introduction of a cat test pipe to the exhaust system.
Where are the test pipes in an exhaust?
A test pipe is the section of piping in an exhaust where the catalytic converter is. Removing the catalytic converter creates much higher exhaust flow. For turbocharged cars, this results in less back pressure and better flow for the turbine. Test pipes or, cat delete pipes, or straight pipes, do not contain a catalytic converter.
How is a test pipe different from a catalytic converter?
A test pipe is essentially just a piece of tubing with the correct flanges welded on to be a direct replacement for a catalytic converter. Whereas the catalytic converter changes your vehicle’s exhaust toxins into harmless gases, a test pipe allows the pollutants to flow straight out of the tailpipe.
Can a cat delete pipe be used as a catalytic converter?
Test pipes or, cat delete pipes, or straight pipes, do not contain a catalytic converter.

Which is better test pipe or HFC gas?
HFC’s will give you better numbers than Stock cats, and (Resonated) Test Pipes will give you better numbers than HFC’s due to the freedom of gasses to flow. Hopefully this broke it down for you enough to make a decision based on your particular situation.
