exhaust under gas tank??
i've noticed a few guys are running their exhaust system as a straight pipe right under the gas tank and one bend (thus causing an angled exhaust). i was curious how safe is it to run the exhaust right under the fuel tank? most places i go they highly recommend against it.. is it just to save their *** so they won't get sued if some freak accident that has the odds of 1 and 1,000,000 happening? i'm assuming people are saying spontanious combustion can happen if the exhaust is under the fuel tank, but is that really realistic?

my exhaust has been under my tank for about a year or so, no problems other then my canister is a little floppy and hangs low
I don't think an exhaust will ever cause a gas tank to explode
There are two things to worry about, heat and sparks. If you bottom out I could see the exhaust sparking but I don't sparking is an issue at all. I have used an angle grinder, and welded under my car and the sparks never blew me up. There is a ground coating on the gas tank that will prevent this.
As far as heat goes, well the exhaust really does not get to hot back there, I mean it does get hot but nothing to worry about. If Honda gas tanks were that sensitive then there would be a lot more Honda's exploding.

You never know. =P That's true though, I mean the coating under there was made for a purpose. I could see if you were going 150+ miles and u bottomed out and maybe there might be an explosion.

There is a heat shield back there, if someone was really really worried, they could make a scatter shield.
But I mean, imagine how many people have owned a Honda and at one time driven over something hot, hot asphalt, hell even a small fire or fireworks is a good example. It will take a lot for it to exploded. And its the gasoline vapors that will do the damage, so your car would have to be leaking gas or have a hole some where. And then you would have to bottom out. Its not gonna happen.
