Gutting cat

[96talontso]

So i got a 3" Megan downpipe and Thermal R&D catback and I left for a camp and when i came back it was on. First i was excited then later I found out to save money my dad had them weld the STOCK (OEM) CAT ON... So im pretty f****** pissed and im trying to figure out what to do, because i can HEAR how much its restricting it... and its not like they can just cut it off now. So im a little bit worried. Should i just gut it out and slap it back on?
Also, (I'm 16 btw) my dad monitors my warning lights and I've told him i want to put a test pipe on and he freaks out about emissions, and thinks it can somehow mess up the car, but he doesnt monitor my money. So could i buy some sort of "tricked" o2 sensor for behind the cat?

Yup if you can solder and have a radioshack close to home you can just eliminate the 2nd o2 sensor. The vfaq shows you how This one. Or you can buy a sensor spacer like this.

The process on VFAQ is a little above my experience level. Any other products like the second that are actually for sale?

Edit: NVM found it. Thank you.

It's actually a lot easier than the vfaq makes it out to be, though if you don't have the tools already it is cheaper for the spacer from STM. Glad I could help ya out, don't forget to mark the thread as resolved!
