I had a slimline dual exhaust for my t-maxx, and I hated it. The way it mounted sucked, and no matter how much pressure you used to zip-tie the exhaust coupler, it would leak and be all over the back of the truck. It is cheap, and that is about the best I have to say about it. It maybe totally different for a savage, but I will not buy slime line ever again. I would look/get the TSAV01 c5H "Category 5 Hurricane" DUAL REAR-EXHAUST PIPE SET FOR THE HPI SAVAGE. This pipe is made by Tsais. It mounts nicely to the truck, and is one great pipe. The price is on the high side ($79.99). The pipe is a fully functional 3 chamber pipe which increases mid-range and top-end performance. The slimline is only a one chamber pop can.
