Product details: dramatically improve mid/high end power by replacing the catalytic converters with a free-flowing x-pipe while adding aggressive sports car sound and throttle response; recommended for track and off-road use only.
Note: the cat bypass x-pipe provides dramatic power increases in the mid to high end of the rpm range. street drivers may notice a small torque loss at low rpm, which is why we recommend the sportcat x-pipe for street applications. please also bear in mind that this system does not include catalytic converters, so the check engine light (cel) will most likely be triggered. This is not an indication of any actual issue with the engine, and does not prevent normal vehicle operation. the optional 0 spacers help keep the cel off.
