hello, i have been looking on ebay for a new exhaust pipe for my truck. i have the XTM .21 conversion kit and an XTM 24.7 motor. i have seen these dual exhaust pipes that BARNBURNER makes and i was wondering if anybody here has heard if they are anygood. i am trying to get something that goes out the back so i dont have all of the exhaust and everthing on my truck. these pipes look very nice too.

NO, Barnbburners or anykind of ebay dual exhaust is bad for you engine. Whatever they say about those "baffles" and "cones" for good backpressue are false. Your best bet is a real Tuned pipe. The Barnburner (any cheap dualie) has BAD back pressue and makes the engine sarve for fuel. In part makeing the engine run SUPER lean and making it seem like the engine is faster., when it's actually ruining the motor. Get a Tuned pipe and an exhaust defeltctor to route the stinger.
 
I have not heard of that particular pipe, but in general dual exhaust pipes are more for show than anything. They usually kill an engine's performance. Mind you, this is all heresay...but I have not heard of many, if any, people who run a dual exhaust and keep it. They usually drop the money, try the pipe, and then dump the pipe when it does nothing but kill the performance of the engine.

It is up to you.
 
What about the CVEC pipes? I hear those are supposed to be pretty good pipes. Some people consider those dual exhaust, because they have two small pipes coming from the stinger. What's your opinion on those Sky?
 
well even though you asked Sky, i'll add my opinion on them to.. :)
Cvecs are tuned pipes. They can a special cone inside of them that help them tune the ehaust notes and inturn give good back pressure. The two stinger on the end don't hinder the perfomrance at all. I'm not sure if they're there for better performance or not though. All i know is that the Cvecs are true tuned pipes and are not "dual exhaust pipes" .
 
i have the XTM 24.7 motor and they dont really make anything that goes out the back tho. that is the problem. i probably will try to rig something and see how that works.
 
I have heard mixed opinions on the CVEC pipes. Yes, they have a dual stinger, but most racers do not run them because most races do not allow pipes with "moving" parts.

I have no personal experience with them, but from an engineering standpoint they should work pretty well. The tunability that the moving baffle allows is pretty decent.

I personally would go with a decent tuned pipe, and there are more of those out there than I could think to list. For the money, the TRAXXAS tuned pipe works really well. It is designed for high end and does give a little boost. Granted this pipe is not for the 2.5 engine, but any other .15 it would work well on. I run it on my Fantom .15FR.

I'll let those who run the other pipes give you their opinions on them, but a search of this site might give you a wealth of information...might take a while to do the reading.
 
do u guys think that if i went and tryed to rig something up to my 24.7 it would mess it up? becasue i was thinking about taking and putting the exhaust pipe hole facing up wards and then putting a metal tube to the back of my truck. i dont think that it would harm anything because it still has to run through the tunded pipe before it hits the metal tubing.

Just becaues the exhaust port for the engine is on the back, does not mean the the exhaust has to go out the back of the truck...unless you absolutely have to have it that way (a personal preference, maybe). You might be able to find a header and pipe that can be set up to go out the back, but most exhaust systems are designed to help the engine burn the extra fuel that comes out the exhaust port (this is done by back pressure pushing the fuel back into the cylinder). For this reason you do not see any excessively long headers or pipes the are at the end of a long maze of tubing. If you are not concerned with the performance of your engine, then you can pretty much run whatever you desire.
 
i am concerened about it because this is almost a brand new engine and i dont want to mess it up.

bryan
 
My question is why are you anxious to run the exhaust out the back of the truck? Because it looks more like the real deal? If that is the case, then there are a number of options, but they all tend to steal performance from the engine. If it is because you think that it must go out the back, then think again.
 
something like the 24-7 is going to need good airflow so any .15 pipe would be a hinderence and could possibly cause damage to that engine. I would use the Dynamite dual chamber .21 pipe for buggies, and now the make a Chrome 1 piece pipe that looks nice. You can race if you want with the Dynmaite it is legal and the dual chamber runs about $25

since your not running a Rossi, or RB I wouldnt think you looking for the most expensive pipe right? these are the pipes I would suggest for that engine.
 
i dont like to get all of the exhaust and grim all over my truck. that is why i was trying to find something that went out the back. but i didnt know if it would do anything to my motor that is why i was asking u guys about it. but now that u guys said that it would rob me of my power they i will probably just go and get an exhaust defelector.

Humboldt brings an excellent point to this discussion. You definitely want a pipe tuned for the .21 size engines.

As for the grime, I'd suggest you continue looking at the exhaust deflector method. I would also submit that if this is a T-Maxx we are talking about, get it dirty...they love the dirt. MTs are supposed to be offroad monsters not clean and pristine road racers.
 
LOL yeah i know trust me, I have a t-maxx and have had it for a little over 4 years. it has seen cleaner days. i think that the only time it has been spotless is when it was just out of the box. anywayz, i think that i am now going to stay with the xtm pipe for a while and put a exhaust defelector on it.

I used to have that on my t-maxx with my hyper 21 and was not impressed in any way on the performance of the pipe.
 
I will keep my comments about the hyper .21 to myself. You bring up a good point. I recommend the above pipes for torquey .21's and bigger as a inexpensive pipe.

Not with my hyper 21. Maybe it was just the engine/pipe combo that didn't work but all I know is that it did not impress me with the combo I was using it with.
