Brandon925 Posted August 23, 2007 Report Share Posted August 23, 2007 I just ordered the Dynatech Supermaxx header system with high flow cats. I am really excited to get them and I cannot wait for them to arrive! I know pleanty of people here have this system, so I wanted to ask how the install went? I'm matching this system up to my stock cat-back with a flowmaster muffler already installed. Is the fitment good? Any feedback is greatly appreciated. Thanks!

AJSmyth Posted August 23, 2007 Report Share Posted August 23, 2007 Dynatech's are great headers, shouldn't have any problems... Quote Link to comment Share on other sites More sharing options...
Vortec MAX Posted August 23, 2007 Report Share Posted August 23, 2007 I've been looking at these headers too. Let us know how they fit, and if they get too close to the starter or plug wires, etc. Mike Quote Link to comment Share on other sites More sharing options...
hugobossvp Posted August 23, 2007 Report Share Posted August 23, 2007 Can i ask what you paid and where you ordered them from? Quote Link to comment Share on other sites More sharing options...
Brandon925 Posted August 25, 2007 Author Report Share Posted August 25, 2007 Oh good that's great to hear. I will post when I get them installed and let you know how I like them I bought them from a retailer not supported on this web site so I'm not sure of this forums policies. I can message you information about where and what price I got them for though. Quote Link to comment Share on other sites More sharing options...
Brandon925 Posted September 11, 2007 Author Report Share Posted September 11, 2007 I installed them two weeks ago and I love them! Installation was easy, straight forward, and well guided by their included instructions. One bolt with the kit came un-finished which I had to replace before installation but it was not a big deal for me. I love the way it looks, and I love the way it sounds. I have the supermaxx headers w/ high flow cats hooked up to a flowmaster cat-back single muffler to the stock tip set up right now. It sounds great and I couldn't be happier!

Vortec MAX Posted September 11, 2007 Report Share Posted September 11, 2007 Any clearance issues around the plug wires, starter, etc? Did you need a lift, or did you do it in your garage? Seat of the pants feel? Mike Quote Link to comment Share on other sites More sharing options...
Brandon925 Posted September 11, 2007 Author Report Share Posted September 11, 2007 Any clearance issues around the plug wires, starter, etc? Did you need a lift, or did you do it in your garage? Seat of the pants feel? Mike No clearance issues at all. It came with an extension for the driver side second o2 sensor(after cat) but didn't need it on my truck. I did it in my drive way, put the car on two jackstands up front, took the front wheels off, had to support the tranny for a little while with my hydrolic jack but it was really no pain at all. I have had my fair share of installs on my past vehicles that were much more difficult. I definately recommend a good set of tools with a few irregulars like wobbly/pivoting extensions but it's not a must-have. It has definitely picked up power on mid-top end. Tires break loose at a dead stop and continue to spin pretty much until I let off the gas. It hits the 99mph limit much faster from a 60mph start. So all in all I couldn't be happier!

Vortec MAX Posted September 17, 2007 Report Share Posted September 17, 2007 I forgot to ask, what diameter are the pipes before and after the "Y" on these? Mike Quote Link to comment Share on other sites More sharing options...
