Sports Exhaust

[bejan986]

I have the factory sports exhaust on my 2002 Boxster. When the RPM is coming down back to idle the exhaust makes a slight rattle noise. I was wondering if this is normal? Is it just the bypass valves closing?

Not likely the valves - more likely a loose clamp or broken weld.

I have had the same problem - on mine, the entire valve assembly is loose on the driver's side. I can move it freely - It should not move at all.

It needs to be spot welded. Until I get a chance to do that, I took some stainless safety wire (ACE/Home Depot) and ran a loop around the valve and the nearest clamp and twisted it down tight.

I've had this wire in place for so long that I only remembered the problem when I saw your post- so at least a year.

The dealer suggested that I take it to a good muffler shop and they can spot weld it. It doesn't look too difficult.

Let me know if you can't figure this out and I'll post a couple of pics. Make sure the car is cool (or wear heavy work gloves) before manipulating the valve.

Yes - give me a day or two - I need to lift the car in order to shoot the area.

Here's the photo - check the valves and make sure they are solidly mated to the bypass pipes.

There's one on either side of the muffler/system.

If the valve/valves are loose, you'll need to have it spotwelded in the outlined area.

Thank You for the picture I will check this out and see if it is loose.
