yesterday a friend and i installed my greddy evo catback..we used air tools so unscrewing was quick..the thing is..the cat has 3 screws sticking out where it connects to exhaust pipe..unscrewing the bolts..half of the bottom 2 bolts broke off along with the screw..and we were .left with the top one..im now pretty sure there has to be leaking since only 1 of 3 is screwed on tightly..the bottom 2 arent..what can i do? replace the cat?

 

perfect excuse for a highflow cat. go carsound

 

the thing is..if i go carsound..id have to get it welded on..im from CA so once smog check comes around..i cant replace it back to stock to pass..what should i do..how are the obx cats that are direct bolt on?

 

go to a junkyard and get one

 

Temporary fix: High temp gasket maker.

 

You can have a muffler shop weld custom flanges onto some Carsound cats (But I think Carsound cats are CARB legal?)

I got a RandomTech Cat that's CARB legal... direct bolt on, and it fit better than stock!

OBX= shit... it's a resonator, not a cat

 

Arent the bolts studs? You could just go get some bolts to replace them, dont even need the studs.

 

no i mean the 3 parts that stick out to go through the exhaust pip holes..they broke off with the studs..
