Default GarageWorkz: Xforce w/ Vibrant GESI Cats

Any input about the X area/part will restrict the airflow? What do you think exhaust gurus?

Shouldn't according to GESI, did you do a before dyno to find out if there was any loss of power with the addition of the high flow cats?

It looks kinda restrictive (almost flattened) at the ""X" section. Are there not resonators on this exhaust?

I was referring to the x section of the exhaust. You right Gesi told me a single cats can handle 500hp.

X pipe is fine. The X-pipe helps pull the exhaust gases out of the cylinder faster than lets say an H pipe.

I too have the x force exhaust - any photos of your setup with cats? I would like to provide a photo to my mechanic for reference.

I thought they were that far back for better clearance, it gets pretty tight near the O2 sensor.

The setup looks pretty clean with the cat locations as the restriction would be at the bend anyways. How much did you pay to get your cats welded on?

My welder is sketical about the space tightness near the o2 sensors cuz the gesi cats bigger and to make way of the another sensor for my supercharger set up.
