the two o2 bungs are for pre and post cat, one goes infront of your cat to monitor how much exhaust is going in and the other goes after it to see how much is coming out. It is just to make sure that the cat is working efficiently

 

I wish I had OCD isn'tstead of IDGAF.

 

hey, remm. did you knotice a reasonable gain? or was it all noise?

 

Yes I did actually. Besides the 3-4 rpm scream it makes I like it.

 

awsome! good luck with it... oh. are you running a stock cat?

 

Dude, this is what the whole thread is about. How crummy my car now sounds with out the cat. But since I dont have the cat the damn car lunges forward like it had a strap that popped.

 

oh. sliped my mind.

 

thanks remmy for making up my mind---ive been tossing around the idea of a exhaust overhaul on mine since i got it last year---but the more i read the more i think i'll keep it stock

 

remmy-- good luck with getting it fixed.. tint ur windows really dark till u get it fixed and no one will know its you??? or get a bigggggggg wing and just look ricer..ppl will understand

Just an exhaust is fine. I got rid of my cat which sucked. I found a solution though. Magnaflow makes a cat the size of a 4" round resonator so I might be getting that.
