I have seen guys N/A use the Obx headers and the knockoff cheaper obx style headers on 2010 Camaros with 500rwhp, corvette guys use them, and on Challenger SRT8's with good results.

im running 1 3/4" with 3" exhaust through a 36" magnaflow muffler....you see my times...i understand they are bigger collectors BUT you have duals which means you're actually flowing more air than me.

just saying buddy....build the truck how you want then upgrade if you TRUELY feel you need to.

i need 1 7/8" to run like needed....im happy with my little ole 12.7 full weight CCSB im good for now.

^^^ thanks man....ive changed my mind a MILLION times...im done...enough is enough.

pick a e.t goal....meet it then stop or set a new goal lol. it's up to you honestly. but i think the obx will do you just fine up until low-mid 12s then its time to step it up to some 1 7/8" or hell even 1 7/8" into 2" with 3" collectors and dual 3".

When does a build become serious? I'm not planning on breaking any records.. I just want a 11 second DD.

Every person who has seen my collector, say man them things are small.. And say I should have went with 3''

All I plan to do is run 11's on spray.. So if people have done it before through obx's 2.5 collectors, that's all I needed to know..

Keniff.. I just wanna be faster then you.. lol

Thanks for the help guys..

try them out first and see. i think the setup would benefit more with some 1 3/4" pacesetters though.

arent the OBX 1 3/4" already just a 2.5" collector? i dunno for sure just saying what i heard.

as for Skipperdaddy dont be mad that it took a Supercharger/cam/LTs/tune to beat my lil ole cam only 6.2
