Yes you need a dump tupe! I ran without mine for 1 week while I was getting it refab'd. I found under heavy boost it began to melt all of the plastic tabs on top of the bumper & black plastic above the grill is now warped slighlty....any longer and she was gonna get goooeeeey.....I also noticed that pickup between gear shifts was also not as reponsive. Don't know if that was my leaky downpipe or dp.....
Good news on my downpipe bolts backing out. I used HighTemp Ultra Red Threadlock on all bolts/stud....it burnt off immediately but 2 weeks strong, no leaks, no backing out. We'll see though.
Hopefully transmission, exedy stage 1, & flywheel will go in tomorrow after work if I get time........Mechanic and I did it in 45 mins last time(thats right, and no bolts left over)....I'm shootin for 30 mins this time....no stock air box to take off
Foo's hit me up on Halo 3 when you go online, ya know......if you want your ass handed too you gramp's! Haha.....it's
