Tuned pipe exhaust leak ideas

Kevlarr · #1 10-25-2009, 07:26 PM

I'm getting an exhaust leak from where the head pipe slips over the manifold stub. Tried wrapping the stub pipe with the yellow Teflon tape and that lasted about 5 miles and blew out. Was thinking of wrapping it in tinfoil next.
What would be perfect is some kind of a high heat O-ring where the head pipe sits against the exhaust flange.

Today was the first time I was able to really ride after installing the tuned pipe a few weeks ago and let me tell you, if you have any doubts as to whether a tuned pipe adds power IT DOES! Before the Teflon tape let go I was cruising at 29-31 on the flats and uphill grades that usually dropped me down to around 20 I was holding steady at 27 all on a standard 44T sprocket.

Is this a pipe you bought, it shouldnt be leaking. If its a manufacturing defect can you send it back? Anyways auto stores sell a muffler repair type tape that with stands the heat. Can it be touched up by welding it or brazing it?

Ive seen aluminum duct tape on new housing construction ducting, maybe home depot or lowes. Its real aluminum foil with a sticky backing.

No it's leaking where the stub pipe on the manifold slips into the head pipe and the spring hold the two parts together. It's kind of a sloppy fit, if I had a swaging tool the right size I'd just swage the manifold stub to fit into the head pipe tighter.

There's usually a piece of hi-temp tubing that seals that up, it's the SBPs one right?

DOH! I have three rolls of that at work. That stuff is duct tape for the 21st century!

Try high temp silicone tubing as used in some dirt bike exhaust systems.

The kit supplied tubing has worked out well so far, prob with the aluminum tape is I figure the adhesive would cook off?

You could clamp over it I suppose... I unno, I don't like how the tubing looks - but I sure like how it works lol

No not a SBP kit but I don't think theirs has a hose there either. This is a pocket bike pipe that I modded to fit my bike.

That looks like the stuff I am talking about. It's kinda hard to tell positively by looking at a picture on a computer though.
