muffler help
 

hello
i having trouble running my lrp 28 with losi tuned pipe, i would like to know if there is something else i should try. lrp runs good in my jammin crtx2 with jammin 3 tuned pipe, but than i put the lrp on my xxl. it just dont want to run right.

What is the engine doing or not doing? If you explain what is going on, you can be better helped to relieve the issue. A video is even better, though not necessary.

On a different note; I've used the Losi HT pipe on several engines without an issue on any of them. I almost always install new rubber grommets on the engine and between the header and pipe if they show even the slightest amount of wear or if there are knicks. The pipe needs to seal tight to the engine to provide enough pressure to the tank.

Another though is to make sure the tank is airtight. If it's not that can cause tuning issues.....
