OTOF

Sounds great. Can you post a picture?

Okay, first of all let me start by stating that I am on my second TT. I originally had a 180 with Garret/Borla... but I sold it to upgrade to my current 225 TTC. I had a problem with my 180 bypass valve wherebye it would make a rattle sound every time I came off the throttle quickly. So EVERY time I shifted gears I would here the chugggaaaa rattle and especially if I was pushing it. The dealer installed a new bypass valve (G valve) and the problem disappeared.

I was afraid that I would have the coke bottle sound on my new 225 but alas it was perfect. I ordered the Bailey valve from Todd anyways because with the chip/exhaust/pulley upgrades I'm planning I figured better be safe than sorry. My mechanic and I installed the Bailey valve together in about 10 minutes and I was looking forward to all the good things that everyone has been saying about it...

I took the car for a drive to test it out and what do you thing I noticed? The EXACT same rattle noise was back. I can't describe how IDENTICAL the noises were. And no power difference either. I drove like that for the next day and went back to my mechanic to double/triple check everything. I reset the computer, checked all the fittings and everything was perfect.

So either I have the FIRST defective Bailey valve as Todd at AWE claims is a possibility or some compatability problem regarding this valve and the 225 was overlooked.

So my question to ALL Bailey owners (especially the 225's) is: do you hear the rattle noise when you come off the throttle aggresively? Example...take off quickly shift at 5500 rpm and listen.

Please help.

Yes I will. Give me some time to get some shots.

I have exactly the same issues you describe. However, I cannot tell you how to fix it. I will say that when I use my Bailey, and the stock ECU, I have a much less annoying sound...

I am open to suggestions but until we have some serious investigative work done, I am afraid we are stuck. Let's see what type of other comments we see over the next few weeks and determine our path from there.
