Drop the Tranny cross member. Only takes a minute when on the lift. The early turbos were loud. The resonator was put on them to quiet the 03 wistle. The foil was added for heat and sound.

Thanks for the info man! You've got me curious as to why this DP was there. Regardless, the new system is awesome. I'm very pleased with it.

BTW, it's your up pipe thats on my truck right now. No scoop and no EGR make a big difference. I plan on deleting the entire cooler this spring when I pull the turbo and intake for cleaning. I'm currently trying to negotiate with the wife to let me build a shop for working on the vehicles and so I can move my tools and work benches outta the garage.

Not my up pipe?

I was under the impression that the stock DP was 3.25". When I got mine off (I had to cut it just below the firewall to get it out) this is what I found. With this tiny DP and the fact that scoop for the EGR cooler takes up 65% of the passenger side up pipe its no wonder my EGT's were up around 1650* on a hard run. Tomorrow I'll be installing the up pipe without the scoop and the EGR cooler hole welded shut and my new MBRP exhaust. Wonder how much the temps will drop and if the turbo will spool quicker. The pics show the difference between the MBRP (left) and the POS stock (right).

All the down pipes I've taken off, I've just assume they were 3inch. Good info, no wonder they pick up when u put a 3 1/2 or 4 inch in.

Aren't you the member previously known as Smut? Didn't I buy that passenger side up pipe from you a few months ago when you pulled out your 04' engine and installed the 07'?

THe 05 up stocker is 3.25 inches. At least thats what mine measures. The one in this thread is an 03 pipe

Mwilbur516 · Dec 12, 2011

Well the 03' pipe was on an 06'. It really makes me curious why it was there, but who knows. The MBRP system is on and working great, and thats what really matters.

Yep.LOL

The tunes are great. I really like Vivians tunes. Had to have her adjust the shifts a couple times, but they are spot on now. I DD the Looney Wild. Give her a call and try it out. She'll adjust it to however you like it and you won't be sorry you tried it. If I ever go to the track I'll have her send me her Looney Wild Race.
