In my opinion you should consider the Thermal R&D Cat-back. It is the only brand I'm using on ALL 3 of my Hondas.
Sounds terrific, looks terrific and the install is perfect on the Prelude. The Civic has had a Thermal since I bought it and the install was also flawless. The CRX unit is waiting to go on.
Remember one thing-every exhaust will be different and each unit must be given a chance to settle in the packing to obtain the best sound and performance.
