exhaust tip

[kevinF]

hey guys does a bigger or smaller exhaust tip work better for more speed or more horsies? this is for a stock t-maxx exhaust pipe btw.


also has anyone done this?

thanks, traxxas thrasher

do you meen length or diamiter?
if you upgrade your motor then you want to get a pipr with a wider stinger. Glen just found this out. when he put the sirio 18 in his maxx he was using a mac pipe for a 2.5. after a year of telling him to switch the pipe, he finaly listened and the motor realy came to life.
if your staying stock motor, a tuned pipe will be best. its the inside baffles that change the power band

i think he just means the defelctor, but not sure...

[kevinF]

im talkin about the stinger.

does a wider or smaller hole work better

[Czech-it-Out Graphics]

u will get a little more power out of a bigger stinger but its very minimal

[Czech-it-Out Graphics]

i doubt u would even notice it

[FreeRideFrosty]

When I ran ST I had one pipe with a single stinger and one with two. I could tell that there was more power out of the one with two but it isn't roar legal to race with...

[Czech-it-Out Graphics]

2 stingers is a big difference compared to just one thats a little bigger lol

[FreeRideFrosty]

meh... volume is volume

[Czech-it-Out Graphics]

ya but do u actually think u could bore out the stinger of a pipe to give it the same volume as 2 stingers, cmon dude its not gonna happen lol

[FreeRideFrosty]

I know not exact but there are some that are close. You would be surprised how little you need to enlarge a hole to make it equal the volume of both combined...

plus the cvec pipes have baffles that move when the RPM of the motor changes. Meaning the pipes baffle gives you more lowend then when the motor reaches a certain RPM it moves the baffle in the pipe to give you more top end. That's why they are illegal, not because they have two stingers

[Traxxas_Junkee]

what do u mean by illegal,in racing?

[squirrel]

it's not ROAR legal. which is like the governing body of r/c car racing. i think?

[Tex]

squirrel is right! I was talking racing

[FreeRideFrosty]

Yeah.. I guarantee that I could bore out a pipes stinger to give the volume of two and then braze in another stinger portion. It would be bigger... and not legal. Therefore not worth the time...

[Czech-it-Out Graphics]

No way i guarantee u couldnt do it, to give the volume of 2 stingers thats impossible since the stinger is not thick enough on any pipe to bore it out that far

[FreeRideFrosty]

Oh... we are talking 2 different things. You are talking about just boring the existing stinger. In that aspect you are totally right. I was saying to basically eliminate the stock one, bore it out, and then fashion a custom one to it if you needed one stinger the size of 2.

You are best having 2 for bashing if you w little extra punch and a single for racing so that you are legal. You may be able to get away with boring it out a little bit but the gains would be minimal...

[Czech-it-Out Graphics]

ok im glad we got that cleared up LOL...if you guys are looking for more punch on a .21 with and inline pipe try a waller adapter it makes a world of difference

[destroy_my_revo_15]

what is a waller adapter?

[Czech-it-Out Graphics]

it is an extension that fits between the pipe and the header on one piece pipes, it comes as a set with 3 longer springs. its like running an extra long header and it gives a significant low end power increase, u could probably find one on any online hobby shop

exactly like that
