So i got my catless midpipe in yeterday and got the o2 bolt and the other simulator peace for the o2 sensor....... the pipe nicely welded and fits up perfect.....BUT

The 2 major problems with the install was:

#1 I cannot get the 02senor out of the stock pipe....so were gonna torch it up today to get it out..or just buy a new one if i cant,

#2 is the new midpipe flange that connects to the s pipe is thinner then the stock one...so i have to put washers in the threads be4 i bolt it on.... The threads weere rusted and week so i got 3 new bolts to put in them today with washers so i can get this done!!!!

Other than that pretty easy install...

Heres a picture of my car in the garage and the New Midpipe

oo

when i finish it up ill post video so u can hear it and pictures so you can see the finish product (nana)
 
doesn't the stock o2 sensor go in the rear bung? there was a bolt in that position on my stock j-pipe iirc.

lol yea ur correct i was just testing fittin size,they are switched around on the car....(crazy)(drive2)
 
when I took my stock 02 out I had to soak it in some WD40 (sprayed it a few times at the threads) so it would have some lubeage... Or PB Blaster would work also.
 
def

definatly gunna soak it and i will be puttin a clip up soon

its a magnaflow catback with the catless midpipe all 2.5 (headbang)
