My MAK cat delete w/3" connect is on the way. Hitting the dyno tomorrow with E85 tune, JLT CAI, MBRP Race catback for what will be my baseline numbers lol. I'll go back to the same dyno after the MAK install and post the results.
You guys that have installed this cat delete, did you cut/weld with the drivers side manifold on the car? Or did you take it off? I'm hoping on the car. I would've just bought headers if I knew I was still taking manifolds off.
Also, my car put down 415hp/382tq saturday. On the same dyno stock, numbers were 375hp/363tq. Nice 40hp/20tq gain from just JLT CAI, MBRP Race catback, LU47's, E85 St00pidfast tune by Jason Herrera (no, sorry Jason isn't open to doing remote tuning as of now).
I too would like to get more info on these as I plan to go this route as well.
