• Loud exhaust question by srivett on 22 Feb, 2005 16:29
• I just chopped the exhaust off of my car and it isn't in as bad of shape as I thought.  Is it possible to have a leak at the doughnut without being able to smell exhaust in the car?  My exhaust was so loud that most ricers would try to race me when I took off from a light.  :lol:  I was expecting to see a lot more than one small leak.  Could it also have been a muffler that's hollowed out?  
  
  Also, how do I get the passenger side spring clamp back on?  It was difficult getting the old one off and I was never able to see it.  Do I need to remove a manifold?
  
  Thanks, Steve

• I do have an uninsulated intake snorkel but it can't be the problem.  My car has been getting louder and louder over the last month.  If changing the full exhaust does fix the noise I am going to cut open my old muffler.  
  
  I've got that clamp set up too, I think I have a 2 1/8" clamp and it just barely fits.  The problem is that I can't see the passenger side mounting point.  I have the drivers side of my car parked on a 1" tall curb so I can squeeze under it but manifold access from below is not possible.  Perhaps I'll have to drive up with the passenger side in the air after I get the new muffler in.

• The solution was to cut the AC lines off of the firewall.  The AC manifold and mounting hardware was making things far too difficult.  
  
  I ended up using two u-clamps at once to make sure I had the exhaust centred.  It is amazing how far those clamps will spread!
  
  As for the noise issue, I don't know what's going on at the moment.  The Bosal pipe did not fit the Ernst muffler very well so I have to pick up some of those stretchy band clamps to replace the u-bolts.  If that doesn't work I'll need to have it welded up.  I'm now getting a real loud motorcycle buzz up near the redline and I can't stand it.

• Steve;
  
   My car had an Ernst muff  :lol:  on it when I bought it, and it was really throaty sounding.

• I fixed the flapping heat shield problem and I'm almost certain that the muffler is making the racket.  I am going to have the guys who sold me the muffler take a listen.  I don't think they've ever heard a diesel that sounds like a ricer before.   :cry:

• I think you will find that all Ernst mufflers sound like that Steve, sorry you don't like it.
