If you want more horsepower, better handling, or a meaner exhaust note without tearing your engine apart, these beginner-friendly performance upgrades are the perfect place to start. All of these can be installed in a weekend, give you noticeable results, and won’t destroy your budget.
1. Cold Air Intake Upgrade
A cold air intake improves airflow into your engine, helping it breathe easier and make more power. Many kits are direct-fit and install with basic hand tools in less than an hour.
Why it works: Cooler, denser air improves combustion efficiency, giving you stronger throttle response and, in many cases, a small boost in fuel economy.

2. Longtube Headers for More Horsepower
Upgrading to longtube headers reduces exhaust backpressure and improves scavenging, which increases horsepower and torque across the RPM range.
Why it works: Faster exhaust flow means your engine can pull in more fresh air/fuel mixture each cycle, resulting in stronger pulls and a better exhaust note.

3. ECU Tune or Performance Tuning
Pair your bolt-ons with a performance ECU tune to unlock their full potential. A tune adjusts your car’s fuel maps, ignition timing, and other parameters to match your upgrades.
Why it works: Optimized performance, improved drivability, and in some cases, better fuel efficiency.
For LS builds, our HP Tuners LS tuning solutions are the go-to choice.
4. Suspension Upgrades for Handling
Suspension upgrades like performance shocks, lowering springs, or sway bars can make your car feel like it’s on rails.
Why it works: Reduced body roll, improved cornering stability, and better traction under acceleration.
Our performance sway bars offer one of the best handling improvements for the money.
5. Cat-Back Exhaust System for Power & Sound
A cat-back exhaust system frees up horsepower while delivering a more aggressive exhaust tone.
Why it works: Less restrictive piping improves exhaust flow, while quality mufflers create a deeper, sportier sound.
