I am wanting to get the Corsa catback for my car, but i dont like the tips that come with it. So i am thinking about buyins some polished SLP dual-daul tips to replace the corsa ones with. Now, I know that the full corsa catback is a 3 inch exhaust and that the dual dual tips are 2.5 inches. Would this really hurt the result horsepower if i put them on the cat-back.


What do i need to do to make this work.

thanks

Scott
