no catalytic converter

My First Ride · August 28th, 2008, 08:46 AM

I have no catalytic converter on my car. I do have a registration sticker, got it legally wink

wink

. But eventually I may get one, for future inspections or whatever. Are they expensive, easy to hook up, and will it hurt or help performance in having one? Im guesisng it would hinder performance but not much.

I got a Magnaflow 2.5 stainless H pipe with high flow cats for about $300 a year ago. I doubt you would see any difference in power.

Removing the Cats are usually good for a +10-15 hp gain.

So, if you put them back on, you would lose that amount.

I seriously doubt that. Maybe 5. High flow cats hardly inhibit exhaust flow.

they are pricey but shouldnt hurt performance much wit a hi flow set.

Not much - Maybe 5 hp.

BWAL · August 28th, 2008, 04:06 PM

what about the sound difference?

THAT is the biggest difference. No cats are definately louder. The only drawback is the stink of your exhaust. A good X or H pipe with high flow cats muffles the sound a bit, but can still sound awesome.

i got tired if swapping my off road h pipe for my stock one every 2 years for inspection so i bought a bbk hi flow h pipe with cats and i ran the same et's amd mph at the track in my 12 sec 5.0 as i did with the off road h pipe . now the stoch h pipe definately hurts performance , get rid of it asap

Yup my car is REAL loud and it does smell but I only notice it when I fire it up initially in the garage, even when I pull into the garage at the end of the day and turn the car off I dont smell hardly anything.
