Mid-pipe concerns I have the exotic speed high flow cat (200 cells) and the Greddy SE exhaust. It shoots flames (don’t want flames) and some of them have my concerns. They have been a few times when going through some twisties. Shifting from a high RMP then getting off the gas real fast you can hear the bang and sometimes I can feel it in my chest. I don’t like that at all. As soon as the engine is at temp this things “POPS” all the time. The popping I don’t mind it’s the 3ft flames out the back I don’t want.

The owners with the mid-pip upgrade, is this normal? I know the rotary is known for flames with upgraded exhaust. Buy dam I didn’t think I was going to have an explosion under my ***.

I have the K&N drop in.

Yes the CEL is on. I can clear the CEL with a scanner but the light comes back on after/during hard runs

Yes it’s running rich, you can smell the gas and see the flames

 

perfectly normal...i have the turboxs midpipe on mine mated up to the stock exhuast and mine pops all the time, but my flames arent that big

 

hmmmm i didnt know you can throw a CEL with a high flow, i just thought it would happen with a straight up midpipe

 

Lol the title of your thread reminds me of mexican food

 

^thats a perfectly useful post

 

Many people don't realize there is a distinct difference between a flame (that you cannot feel, you just see it out the exhaust), and an explosion when fuel ignites and literally explodes. It feels like your tires burst, or a small bomb going off.

I never had it till I was catless and turbocharged. Turning the fuel can eliminate it.

 

I think tuning the mixture is in order to reduce the flames is a must. I see an flash tuner in your future.

 

ive never experienced that...and im full on catless

 

That's it!!!!

I changed my plugs about 500-700 miles ago. Should I double check the gap, or open the gap for a better spark?

 

I live in update New York
Elevation: ranges from 246 feet to 748 feet above sea level
Always run 93 gas

 

Thought of something else, then I do the ECU reset (brake/trip). The car runs good really good. It barely even pop's. Then around 150/200 miles it’s starts acting up. With the CEL being on I know its dumping more fuel to “save” the engine.

 

I used to get flames while driving, while shifting, etc. But the big explosions usually came after I got off the interstate, stood for 2 mins at a traffic light, then started driving. BOOM! as I shift into 2nd or 3rd and turned the corner. The first time it happened I was freaked out. I pulled over and checked for a flat. WTF was that!?

I even made a dumbass thread about it, and people said it might be because I was catless. I was skeptical.

Eventually I got used to it. It REALLY freaks people out who are driving cars around you. They quit driving next to me and hang back. When I got rid of the int-x and went with the accessport, the explosions stopped. AP is much more granular and meters the fuel better.

 

I guess my concern is being N/A and this "explosion" is going to blow me up : ). Besides wasting fuel and having the CEL light on. Nothing is really wrong.... I mean this unburned fuel is not going to ignite before the CAT and blow back in the engine and destroy the engine.


Going to double check the plugs i just replaced to see what specs they are at.

 

But wouldn't it shorten the life of the CAT or is there no difference at all?

 

i used to have flames, the explosion kind, when i shifted while driving hard.

currently, im running the cobb stage 1 (never sent my maps to mm, im lazy.... -_-) and i dont get the explosions anymore. leaned out my fuel a lot, i think my AFRs seem to be pretty good, 14 to 12 under load. the power increase is noticeable, the power is delivered a lot sooner than stock too.

it impressed the **** out of the girls, but i'd rather not have explosions near the back of my car.
