Folks,. I have a specific question regarding TTI headers. Does anyone have experience comparing these two sets of headers for an RB engine:- 2" headers (part number 440-200)- 2-1/8" low-deck step headers (part number 400IB-218)If so, I'd like to hear your experiences comparing the fitment, performance, etc., one against the other.I'm not trying to ignite a debate over stepped headers. Looking for some real-world data, preferably on a B body like mine.Thank you,Jim
