Just had the SLP loudmouth exhaust installed on my '04 yesterday and it looks and sounds great.

My question is will I notice any sound difference if I order and install an X pipe?


I like the sound right where it is so don't want to change the sound.

X pipes will give more HP also won't it?

It helps with the infamous C5 motorboat burble or popping... you won't notice any increase in power.

Don't bother until you get Headers and High Flow CATs...

Is there a difference with headers that don't have high flow cats?

They are going to be louder and stinkier without CATs, no appreciable loss by adding high flows... and depending on where you live the CATs are a must.

Ok, so if I like the sound your saying no power from adding these then right? Thanks tstar
