Where can I get a Hi-Flow Cat. for my Elantra and for how much?

 

anywhere, every muffler shop. $50 and up, best shop online at summitracing etc. now the question is what else are you doing under there.

 

Just about any muffler shop will have them. Expect to spend around $150 including install and disposal fees.

You can get "Random Technologies" High flow cats, but they run about $300+. (Not affilated with this Random)

maybe this gives some info...

 

i learned some really nice stuff at the brullen exhaust tour and would lik eto just mention that their is no such thing as a hi flow cat. all cats use the same core (only 2 company makes them one being NGK and the other being.. hmm slipped offf my tounge) but anyhow if they claim its a hi flow cat it is either 1 of 2 things, a resonator not a cat, or just an enlarged in and out regular cat.

just like to share with you some of my new found knowledge

 

Tsk Tsk, DJ you also for got that Brullen were experimenting with real hi flows, and guess who's gotz one smile.gif . Actually he is right, the materials are the same BY LAW but he did mention some so called hi flows use less material in a bigger in/out and wider shell but this reduces the cat's cleaning abilities. Also some Euro companies ( Random Tech gets their stuff from Germany ) Have better flowing stuff but it's not N/A approved yet. Also do not listen to those who say gutting the cat is ood, yeah it flows better but when you get caught your screwed.

 

heheh i knew i forgot a few things..

but still more or less everything is known now smile.gif

 

I have the best high flow cat you can get I smashed out the guts of the factory one and even thought it's illegal I live in pa and emmissions aren't illegal and you can't tell that t's done because I put the shell back up and from what random says it's about a 3-5 whp gain and best of all it was free.

 

Whoa there! The only thing I said was that Sport Compact Car removed a cat on their Project Nissan 200sx, and it only showed a 2 HP gain on the dyno, on a tuned car.

In my personal opinon, don't gut your stock cat. Pay the $$$ to have a high flow unit installed. If you are going to be illegal...try to break as few laws as possible.

 

Sorry if I quoted you wrong I thought that's what you said, sorry. But yes it's not a good idea to smash it out if your state are bast^&ds about emmissions but mine isn't so what the hell, plus I know a couple lick and sticks just in case . But right after I did it I did feel a big difference. If you do decide to go this way and I will tell you how to do it. Let me know and again sorry Random for misinterperting you post.
