Was anybody able to connect the o2 sensor back up, if you did, did you connect it to the hole in the pipe near the front or in the middle?

Or is there anyway to not have a CEL I have CEL code p00037 now. When I had a single resonated catless pipe I only had CEL for the first few months for p00240, I didn't have a single CEL for a year..catless the whole time.

I think if I could get the sensor to connect I wouldn't have a cel anymore, but it just isn't long enough

the middle bung is for a wideband o2 sensor. plug it up if you don't have a wideband afr gauge

you were lucky not to have a cel in the first place with no cat...

ok it currently looks like this. Are you saying I should put it in the other one between the two resonators? The other one currently has the bolt thing plugging it that came with it. Will it reach if I switch it to the other bung hole?

05rex8

iTrader: (7)

the one plugged already is for the wideband sensor

the way you have it is the correct way...it will not reach the other bung

ah yes I remember I had that problem too I didn't think the cable would ever fit the originally way.. i routed it on the inside of the transmission bracing.. think creatively you'll figure it out.

Oh I see, I missed this pic you posted







It looks like you moved the the cable/wire at the top of the pic

Also, is the cross brace supposed to actually touch the pipe? I'm not sure how big of spacers I need.

alz0rz

iTrader: (41)

ah.. my car

so yeah I actually had to machine a small notch in the frame at that point..

and the frame won't fit at all without you doing some sort of spacer thing there

I am confused as why you want to put the o2 sensor there. Just to get around a cel?

alz0rz

iTrader: (41)

here i did it like this.. keep in mind I ran the cable inside of that bracing there (where I dashed the line)

alz0rz

iTrader: (41)

OH and I forgot to also mention I had to undo the plastic cable tie (or whatever it is) holding the cable ONTOP of the transmission.. that gave me enough slack to route it the way I did.

Ya I just need those two wires to connect up. It's annoying to have a cel on the dash every time I start the car up.

Alzors, thanks, I'll try to get it all figured out this afternoon

they bolt up just like the front.. get a bolt and a nut .. simple not that hard. order gasket rom fluid. or you can make your own.

resurrecting this thread. just installed mazsport midpipe and have gasket and crossmeber clearance issues..

What gaskets(and size, ID for front and rear) do I need for the header side and catback side and where can I get them?

how do I fix crossmeber clearance issues?

alz0rz

pm RaceRoots about the gaskets and fashion up some spacers for the the crossmember bolts

Nadrealista

how thick spacers need to be?

alz0rz

iTrader: (41)

how ever thick you need them to be.. get under there and trial and error with some washers.

those gaskets will not fit our car---sorry dude--i have looked and looked myself. Ended up making my own out of aluminum and then using copper based exhaust sealent. The carbon ones for sale work well BUT they get very fragile. if you ever have to remove the pipe again they usually break.

Nadrealista

funny I was also thinking to use just copper based sealant up front. and gasket at the back side...

why these wont work? wrong size?

olddragger

iTrader: (3)

yep---the inside diameter is ok but we have a different bolt pattern than normally used on collectors.
I made one for the header by using two thin sheets of aluminum (cut out) and then using the copper based exhaust sealant in between the two. works ok.

1/8 in copper sheet makes awesome exhaust gaskets...you can anneal them and make them soft over and over...and they seal great. The only PIA is making them in the first place.....

when I still had that sumobitches midpipe before that sucker stole it from me in the guise of 'fixing it'.... there was that vexiing crossmember clearance issue. I went to the hardware store (not stupid HD or Lowes) where they had the wall of little hardware boxes and got some spacers that fit over some extended SS bolts i got. That worked, but the undercar clearance was woefully little and I think it compromised the bracing the crossmember was trying to do.

The reason I had to return that piece of crap was that the front silencer is in no way strong enough to stand the heat of the rotary and everyhting in there turned to molton metal chard that rattled like crazy... pile of useless excrement that thing was as was it's cheating lying maker.

I had the Race Roots carbon gaskets on my old mazsport midpipe and although they have great fitment and seal well, once I dropped the exhaust to replace the catback, they were pretty much ruined.

Bump. Having a dilemma finding gaskets too and not exactly a fan of one-time use gaskets by Race Roots. What thickness aluminum did you use and where did you get it? I tried the usual Home Depot and Lowes but didn't have any luck.
