Answer 1

Unless you're running nitrous, on a "blown", fuel injected big block engine, why would you need "Hi Flow"?

Goood question.
Your answer would be : NO.
It's a sales ploy.

Answer 2

On almost every exhaust system, the converter is the most constrictive part. If you're looking to gain more horsepower, this is one of the most logical modifications that will still keep your car legal. The stock cat is very restrictive and it's illegal to have it removed, but you are allowed to replace with a different cat (i.e. hi-flow) if your original is damaged or defective (if you replace the original, just lie and say it needed to be replaced).

Answer 3

i own a shop,and all a high flow does is allow the exhaust to pass through it a lot faster,almost without any restrictions at all,and yes if your running a performance exhaust system you will notice a big difference in a high flow,other wise its not going to be that noticeable on a regular exhaust system,but i have installed them before,and they do make a big difference in the running and performance of any engine you put them on,but they cost enough,and sometimes the price just isn't worth it unless your strictly in to high performance all the time.good luck with it hope this helps.

Answer 4

a hi flow cat will create more power bu reducing backpressure and robbing efficiency from your cylinders. a hi flow cat, or any high flow exhaust component, reduces backpressure and increases power (and they usually sound amazing) so a hi flow cat will kick your horsepower and torque up by a good 10-15, percent with the right exhaust system. a cheaper and easier way to go is a cat-back system, with straighter or mandrel bent pipes and high flow mufflers. check summit.com or JEGS.

Answer 5

In the pizza business, the joke is that the smallest pizza they sell is the 'large"
Nobody wanted to advertise that they sold tiny pizza.
In the catalytic converter industry, i'm sure that no body wants to advertise that they are selling 'restricted flow' converters.

In both cases the question is How big, How high flowing. and then you can judge by your appetite and wallet.

Answer 6

initially, do you ought to bypass emissions? because in case you do, you want to maintain a cat, inventory or in the different case... yet you knew that already! one project that I truly have considered is to opposite the cat, so the exhaust flows by ability of backwards. a buddy did that in his ninety 8' Chevy a million/2 ton, he nevertheless handed emissions, and it also made the truck louder. i do not imagine that it gave him any more effective power, yet did not damage it notwithstanding both. you ought to take it off altogether, yet in basic terms to for worn you, it really is unlawful as well. the in elementary words project to guage before doing some thing. Do you've oxygen sencors after your cat? in case you do, you'll start up throughing codes after doing any of the recommendations suggested above. It replaced into you ought to purchase dumby oxygen sencors that you deliver pretend "sturdy" readings to the ECM, yet EPA close that down.
