Performance and sound from changing out the Cats
Phil From Fabspeed here.
I am just taking seeing what members are thinking.
Have you thought about changing your headers to high flow cats or catless headers for performance and sound gains?

No emissions or inspections where I live, so all my turbo cars at catless.
But what is the general consensus on going catless on these N/A motors? Is there a noticeable loss of low end torque and any issues with scavenging? Keeping the cats on my truck was an absolute necessity if I wanted any low end torque for towing.

No significant loss in low end torque, significant top end gain, and sound for days!
