Had the oportunity to talk to the owner of a custom muffler shop today, he is a new account for my business. I've had my eye on a Stillen tru-dual catback exhaust for a while. He can get me a Magnaflow full catback for my 06' 6mt. coupe at cost. Stillen supposedly nets about 11hp at the wheel but, the magnaflow sure looks and sounds nice. Went to magnaflows website and heard all three sound clips and, boooy it sounds nice. Any input from anyone with this exhaust would truly be nice.
