kirks1stss Posted October 27, 2015 Report Share Posted October 27, 2015 I've only had the dynatechs but so far so good. The install wasn't bad at all as this was my first major DIY install. They fit good and I didn't run into any problems with how they fit. I've got the old design. The new design got rid of the crazy driver-side header bend. I would recommend this to anybody as they are a direct bolt on header and can be installed by most people. Cost is a little high but wait for a GP buy and the price will be a lot better. I would say I noticed the gains at the mid RPM level. Good mod What size are your primaries? Quote Link to comment Share on other sites More sharing options...
Steed8302 Posted September 7, 2017 Report Share Posted September 7, 2017 2 years after the fact... I guess someone replaced my trucks cats with a 2-1 Y pipe. I know because I ordered a magnaflow cat back, with the 2-muffler fitting and it won't work with what's there. Now I've got to get a replacement mid-pipe, and might as well do headers at the same time. Looking at dynatech 715-84110 and 715-84230 (headers and mid-pipe, respectively). Anything I should know about this setup before I throw $1200 at it? Quote Link to comment Share on other sites More sharing options...
