Anyone have either or both of them on their car?

Really dont mind the loud sound on the car, but want to hear some feedback about the sound and performance?

 

the muffler bypass is very loud and designed for cars that live on the track. if this is a daily driver I would lean towards the cat bypass.

 

Thanks for the response,

And about the performance, If I go with just the CATBYPASS?

Or just with the muffler bypass?

The car is mainly stock, will it gain power? or loose torque?

 

You will absolutely gain HP & tq through the entire RMP range (with the most noticeable gains at the top end). Keep in mind if you are NOT doing our ECU upgrade with this there is a strong possibility you will throw a CEL.

 

Which gives the more power, the muffler bypass or cat bypass?

 

I did the muffler bypass and then took it off. SOP felt like the car lost some torque. Cat bypass is the way to go from my research. This is for a street car of course.
