Looks good! clean and simple. Try to get some race gas for the maiden voyage its cheap insurance. Seems like I just talked to you a few weeks ago when you were in the planning stages, you work fast!

Very nice, I'd love to see tons of pics like the driver header and crossover etc.
Any pics of the 4" DP into the stock exhaust?

thanks guys. as for working fast i kind of have to. it seems that i lose alot of sleep lying in bed trying to mentally layout and over come all the obstacles. if i dont roll up my sleeves and get out there and do it i dont sleep....also my girlfriend doesnt like to be on the back burner
![]() as for engine flex...that is the biggest reason why i wanted to go with a turbo mounted to the passenger side head. that way all the piping would simply flex with the motor. we will see if the flex couplers are up to the task. like i mentioned earlier, when i redo the piping from the manifolds to the turbos...and i will have to redo it because when i ordered the mandrels i made sure to ordered the thick 18 gauge...i didnt want that whimpy 16 gauge stuff for my turbo build. then one night lying in bed (after i had ordered, received and cut up the tubing) i realized that i had it backwards. lol probably misordered it due to lack of sleep. anyways, my new and improved plan (which i figured out at like 2 in the morning) is to have the drivers side come across like it does and then have the passenger side dump right into it where it currently intersects it and into a single 3.5 inch pipe and a larger 3.5 inch flex pipe right before it enters the turbo. who knows..maybe when the motor is flexing because im hard into the boost the 18 gauge tubing may be glowing so hot it will be flexible ![]() i ll keep you guys posted with more pics of the rest of the exhaust (even though it will be kind of a hack job)

the drivers side was a breeze. the passenger side was the side that gave me a hard time..which is just the opposite of what i thought it would be.

well i slapped together the rest of my exhaust...it is ugly but i plan on going with a complete 3 inch exhaust in the future. i just wanted to get her on the road.
here is a pic...like i said its a hack job....i think there is even a part of a fence post in there somewhere. it goes form a single 4 inch to dual 3 inch to 2.5 at the mufflers. ![]() after i installed it i had to take her for a drive. i took it easy because i was smelling all kinds of stuff burning off. paints, oils, anti freeze that had spilled onto the exhaust wrap. i did kind of get on it... LOOOOVE that turbo whine. i saw it hit 7 lbs of boost real fast so i let up. when the turbo is spooling down it sounded like a police siren winding down lol. i forgot to mention in the build that the air filter sticks out through the core support and is actually just an inch or so from the front grill so i think that helps in hearing the spooling. my tune is way off. before it was even in the boost it was pig rich at 10.0 to 1 so i have to tinker with that. one other thing i noticed is how much quieter the motor/exhaust system is compared to the headers and no turbo. it almost too quiet now ![]() hope to get her out tomorrow and do some data logging.
