Removing the Catalyc Converter
« on: October 13, 2010, 05:13:27 pm »
FIRST OFF!!! I don't care about any enviromental complaints I might get. I'm not going to kill the enviroment by myself. ;)

The car is set for 4PM tomorrow to have it removed, like mentioned in previous thread, the car has 420,000kms wiht the Original exhaust, and I find it rather slow at boosting and sluiggish on the highway, so I figured the cat could be plugged up.

in the spring i\m replacing the entire exhaust with a Magnaflow SS exhaust and Techtronic SS DP.

I'm just curious(MINUS THE AIRCARE BS we don't have that here in NB), Is there any problems in removing it. I haven't found any bad info yet, Just people whinning about the enviroment.

There is no benefit to leaving it on the car any longer than it takes to remove it.

Just took mine off not too long ago, I also took the muffler off last year. It sounds mean, especially around 3000 rpm! :D It also boosts alot quicker :) hardly any lag.

I ran no cat and no muffler for a few 100k buts its too loud. I just upgraded the turbo and went 3inch exhaust. I added a aero xl muffler the car is quieter with bigger exhaust and I love it. It wont be too loud if you delete the cat and leave the muffler.

Yea I don't want a drone since its a highway car, I had a AAZ with a straight pipe before and it got annoying on long drives,

Will no cat make the exhaust smoke more? If its completely stock

So it cost me $38 to have the cat removed... I called someone and have it sold probably for 40 or 50 dollars lol.

Plus she is a bit louder and a little smokier lol.

I'm kinda surprised it smokes more. The cat isn't really supposed to be a soot trap, or perhaps the extra flow doesn't jive with what the MAF is telling the ECU i.e. fuelling.

I punched my cat out - making it a joy to drive again - was considering a new turbo or even IP but thought to go for the cheapest possible solution and she gets up and scoots now!!! Obviously it was a clogged up cat that was causing too much back pressure!

To the plugged cat owners, before removal did you notice the propane/stank smell?
