Ok guys simple question

On my previous car i put a centre de cat pipe in kept the external back box and apart from looking standard the noise from the engine came on lovely with pops and bangs,

i found my WRX a bit quiet for my liking and was wondering whether anyone had fitted the mid de cat pipe can post up a sound link and confirm the engine light does not come on

thanks

 

I would also be interested in this.

The noise is a little..... noiseless

I've looked here: http://www.haywardandscott.com/subar...8-onwards.html

and they have a "cell fix" to stop the engine warning light so would assume it does come on.

If you find anything out be sure to let me know

Cheers
