I Have No Idea

Hello, r33 25det, was running good enough. Brought 550 injectors q45afm and power fc then installed. They were from a bloke who said it was tuned 300kw. I also installed t67 and 6boost so I have to get to the exhaust shop and have the car mobile so they can weld the new exhaust. My problem is when I start the car it sounds rough, it hesitates when I give it has and sounds like its 5 cylinders. I haven installed the 02 sensor yet so that might help an the the timing sais 24degreese when it's idling at 650 revs an it's spose to be 15 right? I'd like it to be atleast drivable befor i take it to be retuned. I've spent a year on my engine bay now it's getting to me. I just want to hear that sweet rb sound again can anyone give me clues?

in my opinion, i would trailer it to get the exhaust done and also to your tuner

but maybe the more wise guys will be able to help you

I have thort of that but I don't want the boys at the exhaust shop to have the hassle of pulling and pushing the car. It's a headache for anyone and also it's less than 1km from my house.

I am always getting cars delivered on trailers and flat beds. Pretty obvious you can't drive a car with no exhaust to a fabricators workshop. I am sure they will be fine with it, I just hope they know what they are doing with your exhaust...

Do they use mig on the car or tig on the bench? Do they clean up the inside with a die grinder, or just mig it on the car and she'll be right? The inside of that exhaust is critical to flow, it needs to be perfect internally to make the power and I haven't seen many exhaust shops able to do the job properly.
