I have the FI LTH's with 12" resontors and CBE. It's a bit loud. I gave up listening to the radio. Also have a G3 cai, and port match intakes for 334hp. For the install of LTH's. The right side takes about 1.5hrs if you're drinking beer. The left side will take about 6hrs if you're lucky. The hard part is taking out the stock heat shield and manifold. Putting the header up in is easy. You have to watch out for the rack+pinion sensor too.
