Ordered the 5" stainless exhaust on Saturday and Received it on Friday, free shipping ( I dont know how they can pay shipping and still make a profit). Opened the box and everything looked great, LARGE but great! Then I looked for the instructions and none were to be found (the main reason for 4 stars instead of 5). Took 2.5 hours to install, with everything fitting perfectly together. Nothing was crooked or hitting anywhere, joints slid right together smooth and easy. As to sound quality, it is a little louder than I was hoping for. At certain RPMs a little drone can be had. In my mind the muffler could have been a little bigger, buy I do realize most Performance Exhaust system buyers want the aggressive sound especially with a 5" exhaust so I chalk that one up to my taste in sound not Sinisters workmanship! Overall its a quality product at a fantastic price made better by the free shipping. I feel bad about the 4 stars, but it should have had instructions as I can see where someone with less mechanical ability may be intimidated buy all the pieces and no idea where they go. Did I mention it was LARGE. Would I buy it again? In a heart beat!

I ordered the 5" turbo back exhaust system in stainless from Sinister Diesel. Ordered on a Saturday nite and it shipped on Monday and arrived on Friday. At no shipping cost to me! I opened the box to find what looked like a "HUGE" quality exhaust system with a very nice 5 to 6 inch exhaust tip included. The only thing missing was a set of instructions! (the main reason for 4 stars instead of 5) It took about 2.5 hours to install the exhaust system on my back without the use of a jack. I started by removing the factory exhaust cutting it into thee pieces (4 if you factor in my factory exhaust had broken off muffler back). I then installed the down pipe and two piece tail pipe and then figured out which pieces made up the rest between the two! Every pipe fit together nicely, with no clearance issues anywhere. I clamped it all together and took it for a drive. The muffler is a little small for my taste, and the truck can be made to drone under part throttle while accelerating. Though a little more or a little less throttle will change the tone. This was the second and lesser reason for 4 stars instead of 5, but I do realize I purchased a high performance exhaust system in 5 inch and most people doing so are looking for a loud aggressive sound and me being the odd duck is looking for a subdued aggressive sound! I fell somewhat bad about the 4 stars as it is a truly great product at a fantastic price made better by free shipping, but there should have been instructions in the box! Would I buy it again? In a heart beat! Would I recommend it to others? I already have!
