Exhaust leaks

I noticed a leak in my exhaust system this morning while it was cold enough to make the exhaust gas visible. After looking into this afternoon, I have found that the seal between the front of the muffler and the back of the cat is shot. I can't get it tight enough to stop leaking completely, although it is a little better now. My biggest worry though is that I noticed a lot of water being sprayed out where it is leaking. What is causing this and what can I do to fix it? The only exhaust mods I have done are a Calmini 2" cat back and a RRO Mega Flow Filter.

BTW, how much will this leak effect my power until I can get it fixed?

Thanks in advance.

Re: Exhaust leaks

Exhaust from a properly working cat will have alot of water vapor in it. The cat will complete more of the combustion process and the product of complete combustion are carbon dioxide and water. This is an oversimplification because there are other products of combustion too. But that is why you have water in your exhaust. The leak will probably have zero effect on your performance, but a leaking exhaust will be a health hazard if the exhaust is getting into your passenger compartment.

Re: Exhaust leaks

OK, nothing to worry about then. I'll just concentrate on the leak.

Thanks!

Re: Exhaust leaks

If you have a short comute to work like I do that water reeks havic on the exhaust. My Zuke doesn't warm up enough to dry up the water and it rots from the inside out. I have 60K on my Zuke and I'm on the third exhaust and need a new cat. Jim

Re: Exhaust leaks

That's why the new Suzukis have stainless steel exhaust systems.

Re: Exhaust leaks

Ronin:

You are probably seeing water that is a byproduct of combustion. If you make short trips in your Sammy in cold weather, the exhaust system never gets hot enough to keep the water from condensing before it reaches the tailpipe.

Try running it a bit longer in cold weather to force the water out of the exhaust system.

You probably won't lose any power with the leak, but you expose yourself to CO poisioning. You should go to a muffler shop and get the leak fixed.

Hope this helps.

Acker

Stainless would have saved me a little over the years. Jim

Re: Exhaust leaks

Does anybody make an aftermarket bolt on cat back out of stainless steel? The Calmini one I got looked worse than the original after only about 2 months. If I can't get this leak fixed, I am going to have to buy a new one anyway.
