Exhaust pipe adapters/spacers/reducers?

[Cra1g]

So correct me if I'm wrong, but the outside diameter of the pregen header is 1-1/4". I'm looking at getting some shorty mufflers for mine, but the smallest diameters I can find are 1-1/2".

Auto parts stores are full of adapters, but nothing small enough to fit the 1-1/4" range. Anyone know where I can get adapters to make this work?

A piece of 1-1/4" ID x 1-1/2" OD aluminum tubing should work. Split it with a hacksaw so when you tighten the muffler clamp it squeezes the aluminum tube down to the 1-1/4" tube. Steel or stainless steel would work fine too, but they're a bit harder to cut and work with.

If you can't find it locally, McMaster-Carr should have it. You can take a look at their part number 9056K38. Other suppliers like Speedy Metals could probably sell you a piece too.

So something like this?

It's a 1.26" ID, which is pretty darn close. A one-foot section would cost $32

That would probably work OK, but I don't know why you want to spend more than the McMaster piece costs.

Good point. The part you mention is only like $11 or so.

I'm also thinking about chopping the pipe right where the stock muffler finishes tapering off and mounting the shorties there. The OD at that point is around 1-3/8", but I think the mufflers would look good there. Only probably would be I wouldn't be able to resell the stock mufflers, since chopping it would ruin it mostly.

Not quite sure what I'm going to do yet. ¯\_(ツ)_/¯
