    V8 Music!

    I waited 15 years to buy a Corvette! Spent many hours online researching exhaust types and manufacturers. Decided on Corsa over Borla. Now my car really sounds like American Beef! I really dig the look of the 4.5 inch tips, and that deep motorboat purr is quite the sound! Daren Gee in sales was very good at answering my many questions/emails. It's been weeks, and I've still not heard back from Borla; plus their max tip size was 4 inch. I plan to own other V8 cars down the road and Corsa will be my choice! ;-) And I don't get any of that dreaded "drone" sound. In fact, I'm considering changing my license plates to: V8MUSIC (don't take my idea my fellow Idahoans, ha ha.)

    I couldn’t be happier. I received excellent customer service from Greg and the exhaust sounds amazing! I am totally happy.
