is flames shooting from the exhaust tips dangerous? my main concern is if the flame can go back through the pipes and into the engine and blow something up. i know that after a while the bumber can melt or whatever if it gets too hot. i have seen and heard of many rx8's do this but is it actually safe?

 

wait. what?

You do realize the engine gets power from a series of explosions, right? You want stuff 'blowing up' in the compression chamber(which is where the exhaust comes from- fancy that!)

Some aftermarket bodykits with aftermarket exhaust systems melt the shrouds, but it's typically from HEAT not from fire out the exhaust. I know I pop flames from time to time while hammering it and I have yet to notice any problems with melting. Short answer: no, fire out your exhaust is not unsafe. Maybe wasting gas and a sign of horrid emissions, but not unsafe.

I get a kick out of the idea of flames going back INTO the engine to 'blow something up' though.

 

Actually, I have heard of this issue way to many times. People are afraid that the flames will go back into the engine and destroy something hence the term Backfire.

The RX-8 don't backfire, it shoots flames. A Honda backfires, it shoots flames AND destroy engines!

 

haha well yea i know its an explosion in the engine, but it only goes in one direction, and i didnt know that if the explosion came from the other end if it would be bad for it.

 

I actually had to research this topic before I bought my midpipe. I was afraid of it destroying my engine as well but rest assure, the RX-8 shooting flames are completely safe.

 

ok awesome, cuz yea thats the main reason im wondering. i am going to get the rp supercat, and i have borla exhaust. i know that this combo shoots flames often so i just wanted to make sure that i wasnt settin myself up for disaster haha.

 

No disaster.
Lots of noise.
Lots of fire.
Lots of environment hating.
Lots of fun.


edit: at least ya still are keeping the supercat. Go with a straight pipe and get some real fire

 

i just dont know how loud it is, nobody has been able to give me a decibel reading for WOT and idle

 

Super cat with Borla is really loud IMO.

I have a TurboXS Race Pipe and the OEM exhaust and it's loud at WOT.

 

I've replaced the socket for my o2 sensor with a spark plug (in my midpipe)... I've been fancying the idea of just attaching a coil too that plug, then having a switch. Can anybody give me an idea of what would happen?

I figure it's a pretty simple flamethrower kit, but would having the spark so close too the engine cause any damage?

 

DO IT! DO IT!


and then tell us what happens after a while

 

I figure one spark is a better than continuous sparkings, but I dunnooo....

 

if you went to SSX, you'd realize that rotaries shoot flames, most of them, with a mid pipe, it just........shoots flames, no mods necessary, just a midpipe=flames

 

It is only dangerous to whatever is the path of the flames... when around 3rd gens I try to keep my bumper away from the exhaust!

 

its dangerous to the rx-8 behind you!!!! you hear that john!!! eddie!!! you hear that!!! dangerous when we rollin!! you guys are burning off my paint!

 

Flames our the back of the car are still in the same direction, out the exhaust pipe....

Chris

 

yes its dangerous ! Sell your car now before something bad happen !

 

Is anybody smart going to answer my question?

 

I have said this so many times that I can't seriously put it any other ******* way

NO IT WONT ******* HURT YOUR CAR AT ALL!!!

 

If its me, I will just say

no.

 

What the heck is a bumber?

 

^omg if u have 2.4k post and u don't know what a bumper is.......I suggest u sell me ur car

 

Actually that is not really true!

The flames will not hurt the exhaust system itself - and you would have to be real close to something behind to actually burn something.

But, the more you intentionally create flames (which is unburnt fuel igniting in your already very hot catalyst), the faster you will burn up your catalyst. A catalyst is essentially a long-term wear item, and the more you do this, the sooner you will need to replace it.

Enjoy the flames, but remember they do come at a price.

right but i have seen videos on youtube where the flame stays ignited and its just inside the tip of the exhaust.

 

LOL! Sorry! At least you weren't tailgating me or else your bumper would've been black,
