This is my 05 v8. I had a FlowMaster Super 40 muffler installed recently. The engine is stock other than an aFe pro dry filter. When I first had the muffler installed, I had the shop keep my rear resonator on. There was almost ZERO difference with the muffler installed and the rear resonator...
Hey all, I'm a long time viewer and just picked up an 05 Sport V8 T4R. When i was deciding what vehicle to purchase it was between the T4R and a 08 Tahoe... after digging through forums I decided with the T4R and here I am!
