I have a 95 max with the greddy sp2. there is an 02 sensor bung after the catalytic converter so i have the most annoying exhaust leak NOISE.
i need a plug to fill it but i cant find anything anywhere. i tried the napa around here and the guy working there acted all dumbfounded. his great advice was "just find a bolt that'll fit in there". which i've tried and its not as easy as it sounds. if anyone can help i'd appreciate it.

 

oh yeha, i forgot to ask, do you think the leak has any effect on performance? i feel like its robbing me of something. probably my sanity because it gives me such a headache lol.
and people try to race me constantly, its rediculous.

 

I believe I saw them at Autozone before.

 

wow really? i'll check thanks.

 

okay i called one store near my hosue and the guy said "nope we dont sell those"

 

Yea, AutoZone here didn't have them either. The guy said we don't have them and asked me why I wanted to plug one up.

 

find or buy a used O2 sensor to plug it.

If you haven't replaced your O2 sensors nows a perfect time.

 

Are all 02 sensor threads the same? I do need to replace some I just figured if there was a specific bolt that'd be nicer.
I actually need to replace two I can just never figure out which one to get and I don't trust the idiots at o'reilleys over here

 

 

No the leak doesn't affect performance. Go to a hardware store and get a bolt... I believe the size is 18X1.5.

 

Thanks guys. Ill check sears tonight

 

all you have to do is use a spark plug (same size)

 

YES THATS THE CORRECT SIZE! Go back to NAPA Chris and get one.

 

Good to know , since i have a 96

Thx

 

Spark plug was too small

 

Spark plug was too small gonna try napa for that bolt

 

The leak DOES affect performance. Just have it welded shut

 

How does the leak affect performance?

 

I heard an exhaust larger than thes 2.5 inch wide ones effected performance so I figured the leak would too.
I found the bolt. Specifically for this, at a specialty bolt store. However its twice as long as I need. It sticks out a little..I didn't want to screw it in too much.
Ima buy some loc-tite and maybe cut it
Thing cost 5 bucks.
Thanks guys

 

Okay, but can anybody prove that the leak affects the performance?

 

No.
