I recently installed a BR catback w/magnaflow and I noticed it would leak in the mornings. It leaks where it connects to the cat and and the two clamps that came with the exhaust. Why is this happening? Did I not tighten the bolts enough?

Here are some pictures,

The next two are the same clamp in the back of the car. This is the only one that makes noise.

Try tightening it a bit more. ;p

 

Ok I will try that and see how it works out

 

And thanks for the quick response

 

The slip fits make sure you put them on snug and tighten them down some more. Also double check your have the clamp installed in the correct direction.

The 2 bolt flange leaking make sure the bolts are tightened down. If it still leaks then your exhaust gasket sucks. Try to find a copper gasket or buy a copper sheet generally used for art and cut it out into gasket shapes to use.

This is a nice gasket as well if you dont mind spending close to 20 bucks for it:

Sorry for the double post.
I will tighten and check everything tomorrow, thanks for the help!
For the 2 bolt flange I used a vibrant performance gasket that was provided with the exhaust and it seemed flimsy. Maybe that's the cause of the leak at the 2 bolt?

 

I used a decent gasket and mine would leak aswell. The bolts need to be VERY tight.

 

x2 tight it hard! maybe try another gasket?

 

If its loose enough to leak, it may be loose enough to work itself apart while drivng. And that would be disastrous.
Impact wrench would likely be handy for the slip on clamps

 

Alright so I did what you guys said and tightened everything down. The second clamp more towards the middle is leak free.
The clamp towards the back of the car doesnt leak water anymore and is noise free, but I can feel a little bit of air coming out even though I tightened the clamp even more. Is this bad or should I buy a new clamp?
The connection at the 2 bolt flange where the gasket is still leaks.
Would putting a second gasket help the problem?

 

With my br tbe, i was more worried about it coming apart with it being slip on clamps. If they were new when you put it all together, you shouldnt need new clamps. The only other thing that many ppl would suggest, is to weld it ever so thin that you could take a dremmel saw to it to brake it off if you ever need to pull them apart

 

Crank it down with an impact wrench. It's the only way to be sure. Also Permatex muffler joint compound will help seal it up. I hate exhaust leaks.
