Those are factory.Are those factory heat protections pads protecting the chassis? Looks brand new, which is why I'm asking. Those headers look awesome (the whole exhaust system looks awesome), and that is some nice power you're making with that setup. Are you going back to the dyno with the headers?
Only use OEM header gaskets, Van is right. Trust me.Right behind you, similar mods with 3:73s ARH and O/R mid
Question, which header gaskets did you use? OEM manifold gaskets or.......?
I only ask because Van recommends reusing the OEM ones instead of using the supplied ones by ARH.
Once all your mods are done, and you start tuning, read your datalogs. If you're getting a little positive knock than add some boostane. Every engine responds a little different.Do you need boostane with those mods? im very similar to you and doing headers in springtime but didn't plan on needing boostane...
Nice ! What were your numbers before the headers? Are they a lot louder than before ? Its the one mod I'm thinking about doing soon.Picked it up and it sounds wonderful!
He did tweak the tune,I told my tuner I wanted it stay on the conservative side. Pulled 741/739.
