OS 21TM w/ 3.3 pipe
 

I searched for an hour, couldn't find anything so here goes.

I switched from the 3.3 to the OS 21tm and am going to use the 3.3 pipe that came with my 5308 revo. Are there any modifications that I need to do to it....I read somewhere about drilling out the baffle or maybe removing it. Any suggestions?

A THS spring mountmanifold and pipe would really wake that sucker up. If you have the resonator now, I would drill it out just a wee bit. Resonators are known for alot of backpressure.

Thanks Clove, just typing in THS into the search engine showed me other options as well. Just needed a good keyword it seems. Thanks!
