Hi, I'm looking at replacing my centre cat and wondered what benefit if any there is in changing the centre pipe at the same time? I'm looking at scoobyworlds afterburner (which i think is manufactured by h&s)

The car is an 02 sti with decat downpipe and racebox back box and want a rumble without it being too loud.
Ideas welcome, cheers

 

It you're replacing the resonated centre pipe, it will definately be a lot louder.

I don't mind it, but the noise can be a bit much for some.
