Hey guys I was wondering if anyone knows anyone or has a American racing headers and borla exhaust setup. The reason I am looking into this is my g8 came with the borla exhaust and was wondering if I can hook them up. One shop I spoke to said they can fabricate them so I was just wondering. Also they are charging about 1200 for install and tune but every retune after would be 350 for any mod upgrades. All in all I would be looking at 2600 what do you guys think. Thanks in advance.
