Improved Performance with Exhaust Spring

This product has greatly improved our vehicle's performance! Based on our own experience we would highly recommend it to anyone looking for a quality manifold spring. The installation was easy and THE results were noticeable immediately .Our vehicle has better acceleration and overall throttle response. The only downside is that it may be a bit expensive for some, but the improvement in performance is definitely worth the investment..

Pros

Improved performance, easy installation, noticeable results.

Cons

Price may be a bit steep for some customers.
