I recently put this system on my 76 firebird with a sbc 350 and I have to say it sounds quite awsome. Installation took only a few hours and was done with jack stands in my garage. I only had to do a small amount of cutting and modification with no welding. The motor pushes around 290hp and has hooker 1 5/8 long tube headers. The system is complete with mufflers and hardware and tucked under the firebird really nicely. For the price I think they are great. I eventually will go stainless but I will wait until I rebuild and install the 77 6.6 liter poncho motor I have. Here are some pictures of the exhaust system under my car and a video of it running. Enjoy.

It is doing quite well. I did scrape on a speed bump and had to readjust everything on the passenger side, but all is well again. The system really sounds and looks great. I may add a cross over pipe in the future. I have added some cheap chrome tips and it really looks hot in my eyes. Here are some pics-

Those pictures were taken about 6 weeks ago. The only thing you will find negative about the system is that you will have to cut some of the center or tail pipe to make each side fit correctly for the Fbody. This is a universal type system that fits a few types of GM cars. THe mounting hardware offered in the kit is not the best and you may have to modify some of them. But for 220$ delivered to my door and with a tight budget at the time, this kit worked well for me. Just one more thing, even though I love the sound these 2.5 inch pipes create, I it is quite tight near the rear differential and 2.25inch would of probably worked better. That is it though, otherwise I am very happy with my small investment into them.
