Exhaust System Upgrades |
|
| The exhaust system is one of the very first things to be upgraded. One of the main things to consider though is how far you plan to modify the car. The larger diameter exhaust systems will reduce low end power, but allow a higher maximum horsepower if future modifications, such as turbo upgrades, are going to be used. The smaller diameter exhaust will most often be best used for those that want a better sounding exhaust note and noticable power increase without losing low rpm drivability. All systems listed here, unless otherwise noted, retain the original dual tailpipe exhaust. |  |
