I'm going to be getting a custom exhaust made, 3" cat back pipe with resonator but deleting my muffler. I am trying to copy the Quadrifoglio quad tip exhaust look but am not 100% sure on what exhaust tips to use. I know that the tips will have to be a single inlet to dual outlet style and installed at a slight angle but, what tips has others used? Honestly, I am trying to save some money by not buying an pre-fabbed exhaust system. I have a custom shop willing to fabricate this setup for me, I just have to figure out how to make it look like the Quadrifoglio's. Thanks to all who can provide so insight on this matter.
