Okay the other day i raced an sti with my tls and he totally walked on me. Everytime it changed gears flames came out of the exhaust, it looks sooooo cool. How do they do that. Is it possible in our tl's? Is it just sheer power, free flowing exhaust, what causes it? I want tl to do it. Excuse my ignorance, just curious.

 

Probably had the CATs removed.Also bigger injectors all done up. All the extra fuel that comes out the exhaust. Normally if it has a CAT the flame stops there acts like a spark arrester.

 

so just take off the cat replace it with straight pipe. Is there any disadvantage to this. And will it also make the exhaust a little more free flowing, meaning more power?

 

Pretty sure you won't pass inspections without a working cat....but correct me if I'm wrong

 

so this guy in the sti probably didnt have inspection. would it work with a racing cat?

 

Have to remember the STi's are a A lot more tunable than the TLs therefore you can dump a lot more fuel in them with a simple computer calibration. The TLs could possible do that too but you will have to remove the Pre-Cats and figure out how to add all thet additional fuel.

 

I dont understand. What do you mean by extra fuel? I did some research, and i found out that you can just remove the o2 sensors, and cat or put a race cat, and it would work.

 

If you were to remove the O2's you wouldn't have no control over how much fuel goes into the motor. The Os sensors measure the mixture and relay this to the computer that way it keeps the mixture at 14.7:1. Also remember CAts burn unburnt fuel so leaving any type of CAT converter would defeat the purpose, also the extra fuel would destroy the CAT.

 

so correct me if im wrong but the only way to do this is just remove the cat?

 

Point is basiclly don't do it...

 

Yea do not do that. Yea my homies STI does that flame thing but nah i would not do that in our TL

 

 

I seriously doubt you could do that in the TL without ALOt of modification & sum serious tuning maybe even boost, the STI is boosted & there is ALOT of fuel being used by it. You can get a str8 pipe though. As long as you get the 02 sensor simulator you wont have a problem with inspection as long as your state (differs from state to state) uses the OBDII as the emission inspection. Here in MD if your ecu reads fine, which it will with an 02 sensor simulator, then you pass emissions. They dont look under the car or put the smog testers on the pipes.

Also to the OP do not get the RT cat. It will restrict the exhaust system on a TLS. Its for the TLPs. Get one custom made or a test pipe.

 

an rt cat will restrict my tls exhaust flow, i thought its made to do the exact opposite, and add a little power?

 

the only cars ive seen get flames out the tail pipe were all turbo'd. (GTI, STI, and a EVO) never seen a n/a spit a flame while shifting... correct me if im wrong

 

also i mean i think it would look cool, but i think youd prob get made fun of by other people on the road, as poser-ish because a TL is not evenly comparable to any decent turboed car and not THAT fast

 

I seen a dodge Neon SRT with flames coming out the back of there exhaust

 

yeah but once again SRT = fast and turboed car as talked about above only seen on these types of cars

 

you easiest solution...

O yea i know i was just making a statement bkuz no one put the SRT out there they put GTI,EVO And STI

 

HAHAHA there ya GO!

 

yeah, and aha ive been noticing i agree with you on alot of things as i look upon other threads and vice versa

 

"dude my piece of shit mustang shoots flames out the back, but im still getting beat by Japanese family sedans?????????" by far one of the dumbest mods ive ever seen

 

the STi is boosted. one of the things with turbo is that fuel is sprayed into the cylinders to cool it down. during the process, the fuel is vaporized from liquid to gas, cooling the cylinder. much like sweat evaporating from your skin.

that fuel then flushes through the exhaust as fresh fuel is pumped in and spark plugs fire. that's what's causing the fire.

"It is another form of cooling that has the largest impact on fuel efficiency: charge cooling. Even with the benefits of intercooling, the total compression in the combustion chamber is greater than that in a naturally-aspirated engine. To avoid knock while still extracting maximum power from the engine, it is common practice to introduce extra fuel into the charge for the sole purpose of cooling. While this seems counterintuitive, this fuel is not burned. Instead, it absorbs and carries away heat when it changes phase from liquid mist to gas vapor. Also, because it is more dense than the other inert substance in the combustion chamber, nitrogen, it has a higher specific heat and more heat capacitance. It "holds" this heat until it is released in the exhaust stream, preventing destructive knock."

so several things you can do. remove your cat, your muffler, replace it all with a straight pipe and redline all the time and hope that you somehow catch fire and burn out your rear bumper, move its way to the fuel tank and exploding your TL.

you can turbo your car

the easiest would then be to buy an STi

 

It made to be free flowing on a TLP which has a smaller exhaust piping diamter than the TLS. So by putting the RT cat on a TLS, yes the cat itself is freer flowing than the TLS cat but the piping diamter on the RT cat is smaller than that on the oem TLS cat. Thus creating a bottle neck causing a loss in power. I would just get a universal high flow cat or test pipe with equal to or larger than oem inlet/outlet diamters and have flanges welded to it & installed. Would actually cost less than the RT cat

 

hahahahaa, i cannot stop laughing!

There you go exactly just get a STI, or EVO!

 

Yea i have noticed that too LOL!

 

or jus cut out this smiley and everytime u want flames bust him out and show them what u got...

 

Cars dont have to be turbo'd to make the flames come out the exhaust. There are exclusive sports cars that do it in stock form as well, such as gallardo, carrera gt, enzo, corvette zr1 and zo6, viper acr, etc.

 

if i were to replace my cat with a test pipe, wont it sound like a civic ricer, and also not pass inspections?

 

this thread is useless...n dont get those flamethrower kits... LAME-O

411 on throwing flames...

cant b done...even with intake/headers/exhaust/pulley/supercharger

removing the cat will make ur car raspy...raspiness means fart can

itll make ur car sound raspy with or without leaks in ur xhaust

removing ur cat will cause u to loose low end torque...but pretty free flowing at high end...itll feel like itll give n give...

just get the RT hi-flow cat...n ull b good

 

bro, think about the cars you just named there

 

Man i agree with you once again. LOL! i was saying the same thing i told some friends and they started laughing. One of my friends wants it on his street bike im like ha dork!

 

The cars you named are high end sports cars. Our cars are not even in the same class as them. I really think it is pointless and ridiculous trying to make flames coming out of a TL...

 

^agreed.

 

Yes Im very aware of what class those cars compete in. Im not comparing my car to them. Earlier someone said that the only way to do it is with boosted cars, all i am doing is prooving him wrong with n/a cars that are also capable of it. I know my acura isnt an enzo, i was just replying to someones previous reply.

 

You know what dude its your car if u want to go and do that go ahead post some vids and pics if u do do it. You will be the only one with it so it will make u different which would be cool

I know i was saying dont do it earlier but hey its his car he might want to be different from every other TL

 

i agree, go figure haha. but IMO i would never do it, and i still dont think its worth any of the work to make it happen. but, if thats what you please, then go for it

 

i have a resonated test pipe and it didnt effect the sound of my exhaust at all, also all of the cars we have put test pipes on gained whp and TQ...also like a said above an RT cat will cause a TLS to lose power...He will be better off just getting a custom hi flow made. It will be cheaper too
