Hi all,

 

so don’t get to get under my gtr much in Hong Kong. Used to get under my cars all the time in the states. 
 

anyway my garage took out my hks silent hi low cat and was wondering does it just bolt back into the system with new gaskets? I’m guessing yes. 
 

Photo attached. Thanks

Yes, just throw some gaskets at it and put it back in. As long as everything is actually designed to bolt up together it will all go back together. My CA compliant exhaust for example can only fit with the specific catback I gave them.

Thanks everyone … will give it a go. Hope the added back pressure doesn’t screw up my weak rich idle issue I have… would be great if it helped it😃

Running rich in conditions where it shouldn't probably won't do great things for catalytic converter lifespan. I would fix that sooner than later.

Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself. 

 

N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.

Just an update  ... Put the cat back on no issues with the car running wise ... maybe alittle longer to spoil up the turbo. Still running rich but waiting for my tuner to come back into town to retify the situation. WOT runs fine with the cat.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
