hmm ok i just ordered the Apexi GT dp and GT spec exhaust from www.turboimport.com...i doesnt say if it deletes the cat or not.. i have searched the forum and have found 2 different stories on this dp...1. that it deletes the cat 2. it doesnt... i am confused does it delete the cat or not ..or is there 2 different type of GT dp running around..i f any 1 can help that would be great

 

It does, the Apexi GT N1 front pipe replaces the cat as-well. No cat, it runs right into your catback.

I don't think it bypasses the cat.
