from experience:
removing the cat will throw a p0420 code reading a rich mixture on o2 sensor bank 2. this is normal with no cat. you will either need an o2 fouler or get hptuned to "delete" the code. cel is gone and you will pass inspection.

I have a gutted cat and it sounds awesome. with stock exhaust it sounds even better. big power gains too.

clear image automotive + 3" catless downpipe + stock 2.0 exhaust = sounds just like stock but better airflow. only sometimes when it's cold around 3-4k rpm's it sounds a tad bit raspy but other than that it sounds just like stock daily driving and jumping on it. i can post up video's for you within this week if you'd like. just pm me and remind me.

the real problem with any type of raspy you hear when the car is warming up or certain rpm's would be the stock muffler. the baffels can't take that much pressure and then it's over it's limit and will create raspy'ness.

if you replace the stock muffler with a turbo muffler it will dispear and hopefully still not sound loud. i will be add'ing a turbo muffler to my car eventually but in the mean time just pm me like i said and i'll post up vid's at idle and everything for you of my car and WOT so you know what CIA header+3" catless dp + stock exhaust sounds like.

haha yeah. aggree'd. but if you have hp tuners you can just shut the code off.

[ff_drift_lol]

that's what I mean by deleting the code. that's what I did for my setup.

big power gains? what in the butt dyno?

[ff_drift_lol]

no dyno numbers, the throw-you-back-in-the-seat dyno i have integrated into my skull is enough for me to know.

[07MetallicSC]

i wouldnt say big power gains no. if it was turbo yes itd be more than supercharged

[ff_drift_lol]

yeah i didn't mean big like 50+hp more like 5-10
