Cats with Superchargers

EVOHUNTER · 07-06-2015, 09:54 AM

My passenger side factory cat is done, its rattling and is all busted up inside, haven't got around to installing my test pipes.

I would hurry and try to get to it if you are still driving the car, if it ends up completely clogging the pipe it might pop the motor.

How many boosted miles?

You could always move the cats down stream. Get the millspec cats welded on to your exhaust. Or order from F.I. it would be far enough down stream to not be destroyed by high egt's

This is what I did. FI put a set of cats in the lead pipes of the exhaust, and they've held up well.

this sounds like the simplest solution. test pipes up front and move the cats further back.

the more elegant solution would be to control the vvel. i am guessing that it´s possible with the new EcuTek rom (not sure though).

for the OP the first option should keep you happy and your neighbors happy with the lower noise level. For me the second is more interesting since I don´t DD my car and love loud noises! So I would love a way to run resonated TPs and keep my PSI up.
