phelan's 370Z (W.I.P.)

Other thoughts:

-As mentioned, I think the USDM models are the only ones that need to be concerned with this. I don't think anybody else has a charcoal canister.

-This interference condition was NOT present during the time of installation. My theory is that the rubber hangars have contracted a bit since install, especially with the very light titanium exhaust that is now hanging from it. Remember, the titanium exhaust is less than half the weight of the stock exhaust. That's quite a bit less force per hangar. The one issue I still have with this would be the exhaust moving about an inch...doesn't seem like there was THAT much play in it, but I can't think of anything else that would cause this to happen.

-The interference was also not noticeable during installation possibly because we pulled down a bit on the exhaust, and stressed the hangars. Given they don't have a spring-like rebound rate, while the car was on the lift it didn't interfere. As time passed, it might have pulled it into the canister.

-The 350Z has similar issues on select exhausts, such as Stillen and GReddy. The solution for the 350Z crowd was to create a relocation bracket for the canister. I'm curious to know if the bracket would work on this. I might have to talk to Josh or Kyle on this one.

-The other alternative is to modify the canister itself. I took possession of the damaged canister I had on Rin since day 1, and I'm thinking if I can file down the affected area, I can eliminate the interference altogether. Thoughts?

-I'm open to any other ideas anybody has.

This isn't the happiest update I've been able to post, and honestly, I haven't driven the car around since I took it back from Fontana. Lots of issues with it right now, so it's best left alone in the garage until I get it fixed.

Any input would be very much appreciated

I'm obviously not a professional so don't laugh if this sounds stupid.

But how about using a longer rubber hangar that is long enough to compensate for the contraction so that it would remain in the same position as when you first installed it. I think this would be the easiest and cheapest way to resolve your issue with the cannister interfering with your exhaust pipe. I think as long as your pipes don't come in contact with your cannister you shouldn't have problems with exhaust heat melting the cannister again.
