Not according to his post where he shows it rubbed through his coolant lines, besides, his engine bay looked like **** afterwards with 10 feet of hose running around the engine. lol

I know it was a freak thing that happened. But the aluminum line could've been easily replaced.nut his decision to do it another way was to clean it up. I tried it once like that in caddis I was working on
I've learned my lesson since that aluminum line dissapates alot of heat. And itso not always convenience but I'll keep that part oem at all cost

she lives! sorry for the shitty video, there is something wrong with my nexus 5, im gonna take another video tomorrow of the idle with the open downpipe. I had to pack it up fast after that video as we had a tornado literally roll through about 30 minutes afterwards lol Seeing 50psi oil pressure at idle at about 750-800rpm, got alot of tuning to do after I get the downpipe welded up.

I suppose I could check with a mirror, but I wouldn't cap it off. My car is all stock so it never had anything on it I'm pretty sure.

I'm not sure then, is it possible it could be different for different years? Mine is an 08, and I don't think it ever had anything attached to it.

I didn't see it in the vid but I assume you mounted the tranny cooler already. If not don't throw that bumper on just yet. Is that a baseline tune you have or is there more to it? What is the rest of the exhaust going to be?

I had to pull the tranny cooler, didnt have enough hose and the mounting point wasnt right, so im gonna wait to install it and im probably gonna sell this one and get one that i can use AN fittings and pushlock hose straight from the trans. Wasnt happy with the setup, but im not too worried about trans temps being that bad in the short term.

Baseline tune is just merely disabling certain features like CAT overtemp, DOD, idle adjustments, idle spark adjustments, PE and some minor fueling changes, shift tables for the 3.29 gears, rev limit, torque management etc. I really have to find someone who already has the 3.29 gears tuned on HPT to compare notes, because im a bit skeptical that these numbers are right.

I noticed big improvement after installing mine. As long as your getting air from the grills to it it should be fine. Cant really be seen anyway, I'm thinking your a little more, oh whats that word, oh yea **** then me lol. Well it shows in your work . You have this beast all figured out, your right, it will be fine until you get it perfect.
