Factory cats, red necks and exhaust mods

Eric,

Your sig. shows your car is down on power..??? 401 RWHP with smoothies, filers AND catback? Shouldn't that be about 430 + RWHP?

Eric I have been thinking of doing the same with the factory cats to my GTS. Right now I have Bellanger Headers with the Random Tech high flow cats and Corsa 3" exhaust. It sounds great at idle and freeway cruise is not bad with the Corsa but any time I jam the go pedal the high flow cats make it very loud. I'm afraid every cop in town who can't see me will be able to zero in on the sound! I have been told to replace the short high flow cats with the stock cats opened up to 3" to quiet it down a bit. Thanks for your post, now that I read you have done this with success I will probably do the same.

Eric, one thing I noticed with the high flow exhaust the GTS does not get as hot inside the car. When you put the 3" factory cats on did you notice more heat in the car compared to the high flow cats?
