Each Ulter Sport Rear Silencer offers performance gains, a sporting exhaust tone and improved looks from the stylish tailpipe designs. The performance gains are achieved with the use of sports silencers with free flowing pipe work which offer less restriction for escaping exhaust gases compared to the standard oe exhaust. Internally the back box has separating walls made of stainless or aluminised steel which are tailored for cars exact characteristics. You can expect a deeper sports exhaust sound when you fit an Ulter Sport back box which is a by-product of it being less restrictive.
