Bolt In a High-Flow Exhaust
The exhaust may be the… erm… wastegate of your cars respiratory system, but a free-flowing exhaust relieves pressure on the engine and can return a little bump in horsepower as well. Better sound is just a welcome side effect. yopu can get a exhaust for around $900 - $2000+ dollars.
Replace Your Bushings
Replacing bushings may be a little bit more involved, but you’ll be glad you did it. Between the suspension and the frame, and the chassis and the engine, factory rubber bushings help kill vibrations throughout your car. The problem with rubber bushings is that they wear out and crack over time. Polyurethane bushings not only last longer than standard rubber counterparts, but they also do a better job of quelling vibrations and minimizing weight transfer. You can get them for $200 dollars.
