If you have good couplers, you can flip the edges of y pipe with a plyer. That should keep it intact.

Thanks for the input guys. I will be picking the car up probably Friday. Definitely will pick up that IAT while its on sale. I also have been looking at the ETS Fmic since it is 15% off right now. FSR agrees that I should look into an FMIC since the temps seem to skyrocket. Also agreed that I should look at increasing the wastegate springs to 12psi.
So before the dyno revisit it looks like I will be installing an FMIC, putting the test pipe on, replace IAC (may have to wait till car is back to shop to recalibrate), and pressure testing both intake and exhaust to 27psi. There are also a few 9* bends in the fuel feed line that I want to try to get rid of. Oh and install some higher rating wastegate springs.
The ebay Y-pipe is actually popping off from the throttle body since it isn't reduced in size. The weird thing is that he said the y-pipe isnt popping off at peak boost. He said it is a bit after when boost beings to drop off. Any ideas what would cause this? Ian is thinking there could be a lot of turbulence or something going on inside. I believe all this occurs at the same time the AFR starts to go erratic.
I don't think they were able to get the car on the dyno without the high flow cat. Probably just enough time to checkout the tune on the street before he leaves for the Thanksgiving.
Is it even probable to have such a large restriction in the exhaust side to cause some of these issues or should I also be looking at removing the valve covers to see if anything is failing inside. Before dropping the engine back in I did a cold leakdown test on all the cylinders and they were all good.
well since you are going FMIC then forget about fixing the Y pipe. Yes cat can cause a massive back pressure. I'm not sure how much of improvement the high flow cats are, but I remember Matt said a car with cat and slip on down pipe was keep popping the exhaust pipes because of too much back pressure.
I guess we will find soon. Should be interesting to get a comparison with the high flow cat and test pipe. Will be tempted to get an exhaust as well if the quad tip goes on sale on black friday. Thank you familyMan for pointing out the discount at Ninja Performance. If I remember right, Napa was wanting $130 for an IAC.
Are you running an aftermarket DP?
Also.. Why not go for higher rated springs to be able to hold the boost better on e85? I have 16-22 psi (red) I believe in mine.
Haha. I wanna check out your car..
As we discussed on the faceybook.
Get them the test pipe and have them do some runs to see if the problem cleans up.
Also it is the season for buying, black friday sales are here and may as well go ahead and spend what ever deployment money you have left.
Don't forget you have to have the car back to you prior to Dec 13th so I can check it out when I am down there.
Yea 3sx downpipe. I really wasnt sure what spring to go with for 91 octane so I stayed on the safe side. I will probably move up to the 10-14psi spring.
You in Socal?

Yup. Live in SGV area and work in Ontario. Are you in the SD area or out by FSR?
Would love to compare against another e85 billet car.. ;[p
