removing cat back

**ssmike** · 08-17-2008, 06:44 PM

hey i got a 99 camaro ss with a 3 inch flowmaster cat back and a cut out even witht the cutout it feels restrictive and is way to quiet for me i was think about taking the catback off and leaving it open exhauts where the y pipe goes 2 into 1. my question is will this casue a loss of power because of back pressure or will it add power?

It will basically be like having your cutout open.

If you want it loud, just get an SLP Loudmouth with the shotgun resonators and no mufflers. Then at least you won't have the horrible resonation and vibrations from a dumped exhaust, not to mention the fumes. Plus it will look nice and will sound much better than an open Y.

I agree with Wesman. I would take a bullet resonator over any muffler-less system. Just doesn't look good or sound the best imo.

wait what is resonation?

resonation is the reverberating of sound off of the ground and surounding materials, usually resulting in an annoying drone and vibration of the car. It will really bring out those rattles. Not to mentio the fact that by not duming the exhaust out side of the vehicle under body you would be exposing the underside to excessive heat, and corrosive gases.

Also coupled with that would be huge amounts of carbon monoxide. If you want to go red neck (IMO) atleast dump it near the rear axle
