Will it be OK to use with a decat (testpipe?)?

any help much appreciated as im getting **** fuel economy atm,

thanks in advance

 

anyone?

 

Local parts store sells Bosch O2 sensors for around 50-60. If you want to go with an OEM Denso it will run about 90-100. Some people say the Bosch sensors don't last as long as the Denso ones but I haven't had any issues with mine at all. I had a Autozone special for about 3-4 years till I removed it because I didnt need it anymore, not because it went bad. Seeing how you are international i am not sure. There is a website that sell just O2 sensors and has them at a decent price. I just cant think of it right now off the top of my head.

Edit: This is it I think.
