High Flow Catalytic Converters

[ghosthunter]

Good Day tsikot!

Anyone out there had their stock catalytic converter converted to a high flow one?
want to free up some torque sa kotse pero ayaw ko naman yung mabahong amoy
(like the exhaust smell of a newly started car) to last all day long.

any experience?
1st hand experiences would be really nice.

any known shops that sells these high flow cats?

I had mine done when I turbocharged my corolla many years ago. The stock cat wasn't up to the job anymore so I opted for a cat upgrade. This was the time NODALOS was still open and I bought my from them. I had it installed and the restriction (backpressure) in the turbo was reduced as the turbo would spool up quicker after the cat upgrade.

What is your car and current mods anyway? Unless you are running really rich, a cold start shouldn't smell like gasoline.
