Default Resonator Pipe Question

I am up for trying new things to add power. I read a lot about
drilling the stinger of the Traxxas Dual Chamber pipe.

What will it change? Low end, upper end? Will negatively affect either?

I am afraid to drill my relatively new pipe and find it adversely affects my performance.

Has anyone done this that can input here?

Thanks

I have done this on my revo running a O.S. 18TM and TZ, it hurt low end slightly but helps agood bit on the top.

I liked it but the one downside is that it is as loud as a trinity pipe now!!!

Thanks for the input.
My Jato screams like a scalded cat. So I think I'll just leave the pipe alone.

Today I removed over 3 more ounces of weight from it. I upgraded the turnbuckles to aluminum. That saved 17 grams.
I thought it would have been more. I also swapped out the receiver battery from the Traxxas NiMh(106gr) to
a Lithium(36gr) and saved 70 grams.



Thanks again for the input.

I hade the trinity pipe on a HPI MT2, i ended up knocking the stinger off of it on curb one night. I thought the pipe was ruined, i was ready to throw the truck in the bed of my truck and go home. My buddy talked me into running it like it was. The thing had stupid topend and i mean stupid. It lost a huge amount of bottom end grunt though. I have since then studied on it a bit and have just come to realize the more you open up the stinger the more topend you get at the cost of bottom end rip. But be careful you go to far and it kills it all around.

And i will tell you right now, after i knocked the stinger off my pipe, I would blow a glowplug out about every 1/2 gallon of fuel. Only reason i could think would have to be the lack of backpressure allowing outside air back into the motor after high speed runs while on the brakes. (thats the only time it would do it) And for me glowplugs blowing out rarely ever happens. I have gone gallons on end without losing a glow plug except for that pipe.
