coal miner Posted February 12, 2014 Report Share Posted February 12, 2014 I need help picking the size. I've spent 3 hours reading on the net. I'm so confused it's crazy. I read one thing and read another and it's totally different. I think I need/want the 1 7/8, but some say you lose power on low end and some don't. I plan on doing a 408 later this fall but I don't want my truck to run like crap incase my plans change. Quote Link to comment Share on other sites More sharing options...
1BAD2K Posted February 12, 2014 Report Share Posted February 12, 2014 Get the 1 7/8". If there is any down low power loss, it wont be noticeable. You'll be glad you went with the right ones at first. Quote Link to comment Share on other sites More sharing options...
JC03SS Posted February 12, 2014 Report Share Posted February 12, 2014 1 7/8 if plan on making some big power. I can't really see it hurting either way you go really unless your at wide open throttle. Quote Link to comment Share on other sites More sharing options...

texaSS364 Posted February 13, 2014 Report Share Posted February 13, 2014 Your definitely gonna want the 7/8 if you go with a 408 Quote Link to comment Share on other sites More sharing options...
coal miner Posted February 14, 2014 Author Report Share Posted February 14, 2014 What kind off exhaust setup are you guys using? I was thinking of putting in a 3 inch y pipe and running 3.5in the rest of the way. Quote Link to comment Share on other sites More sharing options...
JC03SS Posted February 14, 2014 Report Share Posted February 14, 2014 If your gonna go with a 408 soon I'd go 3" true dual to an x or a muffler with an x built in. Unless you wanna run a single exhaust. Single I'd go dual in single out no less than 3.5". That's just me. Quote Link to comment Share on other sites More sharing options...

Downeast Johnny Posted February 23, 2014 Report Share Posted February 23, 2014 We'll I finally turned losse 1400 bucks and orders my headers today. Way to go Rick. Let us know how the install goes. Some say it's a piece a cake, some say they have some trouble. What are you going with for the back half of the exhaust? Quote Link to comment Share on other sites More sharing options...
coal miner Posted February 23, 2014 Author Report Share Posted February 23, 2014 3 inch ele cut outs then reducing it down to 2.5 duals into a borla xl out the side. I'm going to fab my own cat back out off mandrel bent pipe. Quote Link to comment Share on other sites More sharing options...
