I am looking at buying a Manta exhaust for my car. My car has 1 outlet now, the Manta has dual outlets. To do this I will have to modify (cut) the rear valance panel!!!!! Has anyone had to do this before?

Is it worth it? My car is in average shape so show quality is not important.

Does Anyone here know about the Manta exhaust? It is part # PEL-911-MON-01 in the pelican parts book.

Thanks
Shawn
