Ive had some before, from the U.S though. Cant remember the brand but bought them off their website. Had them put on and i was surprised i could actually feel a power gain. This was without a tune too. But the tone they put out was soo un-wrx it made me cringe everytime i drove it. Sounded like a 1.5 lancer with a cannon on the back. So i paid to have them removed and binned them. Didnt even bother to sell them. didnt want anyone else to go through the same horrific discovery as i did
