Is there such thing as a performance a.k.a high flow catalytic convertor?

Question

I drive a 2004 Dodge Neon R/T. I've been saving up money to do some bolt on performance upgrades to my car. I wanted to add a high flow catalytic convertor to my exhaust system. I already have a Magnaflow aftermarket exhaust put on. I went to the muffler shop to talk about price, and the guy there told me that high flow catalytic convertors don't exist and that a catback is a catback and it's the shape that makes the difference and you have to get in according to the emissions standards for your car. I'm asking if this is true or not. I just bought exhaust headers to add on also. I already have a short ram intake installed also. If high flow catalytic convertors don't exist, what else do I need to add besides headers and the muffler?

Answer 1

Yes, there is such a thing, does it really improves a car performance? No.. not at all.



If you really want to know that mods would improve your car, you can use a car performance simulator to help you with that, try at http://www.nxgtrsim.com

Answer 2

The guy who told you that is full of crock. Yes, there are high performance catalytic converters. They have less catalyst material and usually are available in larger diameters. They might not clean up the exhaust quite as much as the OEM, but they aren't as restrictive either. Do they offer power gains? YES. The other guy trying to sell his website subscriptions is a bigger scam. Also, not all cat-back exhausts are created equal. Diameter, number of bends, muffler design, location, size are all variables. The more straight the piping, the more power. Too big hurts power. Too small hurts power. Straight through mufflers are more powerful, but louder. Baffled mufflers reduce sound, but also restrict flow more. The cat-back system is a non-emissions part, so no, you don't have to get it for emissions standards. If you really wanted to, you could put a 6" diesel exhaust on it. It wouldn't help the car, but you could do it.

Answer 3

confident, the vehicle gets louder. The catalytic converter additionally has a muffling result and putting a bigger unfastened pass cat converter on might have much less of a valid muffling result.
