So far I am happy with the kit... had it on a month or so.... was not sure if the 50HD was goona be lound enough for me... but it sounds really good... wakes my Power Wagon up!! the way this truck should sound!! the kit was around the same price or a lil less than the shops around were quoting me for.... and this one is stainless... not like they were gonna put on my truck.

Awesome sound and quite a power boost for my 5.7 Hemi.

On the advice of several friends I took my system to a professional exhaust installer who welded the entire outfit in, no clamps anywhere. Extremely pleased with the sound and power boost. Everything was delivered promptly and in excellent condition.
