removing Front exhaust piece honeycomb

FCpilot · 05-21-2009, 10:29 AM

Has anyone taken the trouble of removing the honeycomb within the front exhaust piece? Has this resulted in any net gain in performance? Does this result in damage to other exhaust components?

Thanks for your input

You talking about the ceramic matrix in the catalytic convertor?
Do you have emissions testing???

I'm talking about the Pre-converter....

My car is exempt from emissions in my state.

I have removed it from all 3 cats.
I noticed a huge power jump (maincat had broken down) from stock, slightly louder, but much more fun to drive.

which is easily remedied by plumbing the feed line into the air pump. It will have no bad effects beyond those of the normal system.

Thats what i did, with some valves to adjust it to open and close when i want, and i have 5 rx's, all of them are s4, i keep forgeting that the s5 ports activate differently lol. I know what im talking about for the most part though

True, or using a RPM switch to activate a pump.
