Our cat-back exhaust system (mid & rearsection) can increase your car's performance. All our custom exhausts are free-flowing, that means there are minimal restrictions within our exhaust silencers. Your standard exhaust system will have restrictions within the exhaust boxes known as baffles & chambers. This type of exhaust box reduces the sound level with intersections & sound absorption material. This gives a negative effect on the travelling direction speed of the gases causing them to slow down & delay the process. Any questions please ask ###128578.
