RickRolled Posted March 21, 2014 Report Share Posted March 21, 2014 Hey guys quick question. When i get back im buying some dynatech headers for the truck, since im supercharged i know im going to go with 1 3/4 x 2 1/2 size. Anyone know of any good deals going around right now?

silveradoss_3 Posted March 21, 2014 Report Share Posted March 21, 2014 Don´t know of any deals. If youre going with the dynatech I´m pretty sure you will be satisfied. Love the sound! Are you planning on deleting the cats or keeping them? Quote Link to comment Share on other sites More sharing options...
BLOWN SS/T Posted March 21, 2014 Report Share Posted March 21, 2014 Why not run a 1 7/8" header into a 3" collector and merge down if you need to. If I were supercharged I'd run a 1 7/8 into 3" duals and if you wanted to neck down, I'd do it after the outlets of the muffler/s Quote Link to comment Share on other sites More sharing options...
RickRolled Posted March 21, 2014 Author Report Share Posted March 21, 2014 Do they make 1 7/8x 3"? I already got true duals with the stock pipes and a x pipe. I plan on deleting the cats as long as my base doesnt start making every vehicle that drives on base get smog tested. Utah is stupid like that.

BLOWN SS/T Posted March 22, 2014 Report Share Posted March 22, 2014 Wow those are pricey, but if you want a quality piece and stainless that's the way to go. Idk if kooks makes a specific one for our trucks but you can run the f body style if your not AWD and have to fab up a mid pipe due to the collector positioning. TSP makes a 1 7/8 also but not sure if it's a stainless metal. And pacesetter is another one but probably won't hold up in rough climate states.

Fireman31 Posted March 24, 2014 Report Share Posted March 24, 2014 Dynatech now makes a 1-7/8" primary.....to the OP, what are your mods? What are your goals for the truck? That will dictate what size primary, collector, and exhaust you choose.... Quote Link to comment Share on other sites More sharing options...
BLOWN SS/T Posted March 24, 2014 Report Share Posted March 24, 2014 He's running an mp112, so that alone would call for more exhaust. I'd say the 1 3/4 on a 6.0 engine would probably be better suited for a lightly modded truck/car now that the availability for a 1 7/8 is out, not to say that the 1 3/4 can't go far, cuz it's taken a lot of people to some fast times. But with a blower, you don't have to worry about any low end loss going to a larger primary. It'll only be gains and more room to grow..

RickRolled Posted March 25, 2014 Author Report Share Posted March 25, 2014 Thanks for the advice guys. I think I will be going with 17/8. Quote Link to comment Share on other sites More sharing options...
BLOWN SS/T Posted March 25, 2014 Report Share Posted March 25, 2014 If you run 3" collectors you have the option to keep 3" all the way back or neck them down. Most people that are running a true dual setup will run 2.5", there's a few ways you can do it. There are comparisons of how different exhaust setups, dual, single, diameter size etc... And they show up to how much HP there good for. I prefer to just run an exhaust cutout as close to the engine as possible. Quote Link to comment Share on other sites More sharing options...
2003blackSSS Posted June 13, 2014 Report Share Posted June 13, 2014 Did you ever buy the dynatech headers? We are starting to sell them and I was curious as to the fit of them. They also show a bolt up "y" even though these do have y pipes, but they connect up to the factory cat back exhaust Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted June 13, 2014 Report Share Posted June 13, 2014 Dynatechs fit well, many here have them. They are a true bolt on with zero fabrication needed... Quote Link to comment Share on other sites More sharing options...

coal miner Posted June 15, 2014 Report Share Posted June 15, 2014 Dynatechs and ARH headers are the best you can get. Personally I got ARH. Quote Link to comment Share on other sites More sharing options...
