Has anyone seen any performance difference between the muffled and non muffled SPP 45 outboard pipes?

Thanks

Zach asking questions about a 45 ob ? I think 2020 dist racing is going to be a lot of fun!
John,
We will have several 45's and a couple new 21's. Hopefully we can breath some life back into the Nitro classes. Do you by chance have a stock 21?

Thanks,
Zach

I personally prefer the unmuffled and adding a real muffler. For sound/noise reasons.

They both (muffled and unmuffled) perform very well, but I am not a fan of the standard muffler noise, compared to a proper muffler fitted to the unmuffled version.

So go with the muffled version as the easiest way, but (IMO) you really need a muffler fitted to the unmuffled version.

Zach,
We have tested both and are getting the best results from the muffled version. I sell more outboard pipes for SPP than any other distributor, and I can tell you the muffled version outsells the unmuffled version 10:1. I keep both in stock. Thanks.

Hi Ron,

Are you saying that because more muffled are sold that they must be better?

Or that you (or someone) actually did back to back testing?

I find it interesting that with such limited "muffling" on those pipes that it would make much difference in actual performance. But great to know if it does!

Either way, it is a great pipe in either form.

Edited to add the quote

Cheers
Kris

Kris,
Yes, I tested both same day, same setup. Sometimes you cant understand why things work better or not, but results speak for themselves. Muffled pipe is what I have found runs the best on Nova 46, non-muffled on Nova 21 KEEP. Thanks.

There is no pipe made that works great across the board because people like to cut up engines and you cant expect a pipe to work the same on one engine with 180 exhaust timing and another with 200 degrees of timing.

I’ve owned 3 or 4 cooper pipes over the years, never did work great for me personally. I’ve seen them scream, but.....
