How do I reduce the back fire from my 07 STI? I'm running just a downpipe with no muffler or midpipe.

 

so ur running straight DP???

well thats always gunna have back fires cause of that...

 

Wow....

 

thats exactly what I said out loud

 

rofl for sure

i think we can call that wol (wow out loud)

 

NOOBS now-a-days

 

not to sound too short or rude but sell your car and buy a Honda/SRT-4
driver's like you give us subys a bad name--no offense
there I've said it

 

^^^what does it mean to be a subaru driver? dude can buy whatever the hell he wants and do whatever he wants to whatever he owns, who are you to tell him what to do or how to act? should all black people be ghetto thieves and asians be passive nerds?

 

wtf omfg. hahaha hes so right mayne

 

hey I once had my sti with the dp only just to **** arround...leave the guy alone he is varely getting know his subaru...he will learnd trough mistakes, like getting pulled over for no exhaust, then he will put it back on so just give him time and let him know whats up dont be a d..i..c..k!

 

reconnect the midpipe and muffler

 

+1
Soggy is right definitely reconnect your midpipe and muffler.
Your STi isn't going run correctly running just the downpipe
exposed like that it's a bad idea.If you want a loud exhaust note you should run a straight pipe all the way to the back of the car I agree on
that idea not mention you could be harassed by the pigs because
it is illegal to not have your exhaust go out through the back
of the car.

 

Okay I'll think about reconnecting the midpipe. But maybe not, I'm not worried about the Cops since we hung the muffler to give the effect that the system was intact. If it is going to physically effect my car then i'll fab something. I appreciate the post that weren't rude and welcome the advice from all. It would have been nice from those who were rude !#@holes to just give advice instead of acting like master racers and mechanics and writing silly a$# comments. Maybe some people want to try something different and not have that same Subaru rubble that comes with the stock headers or maybe some people want to have a load exhaust or some want a quiet exhaust. I'm not driving to go take pictures of geese flying away like in the Subaru commercial. That's why its called BOLT-ON, I can take it off and put it on whenever the Hell I want. So if you don't have anything positive or just HELPFUL tips or suggestions, please avoid my post, my name is pretty easy to remember. Thank you to those with positive advice and tips.

 

well if you are going to keep it like that....thats bad ***! I remember when I was cruising like that...lol...lots of looks from poeple and hater poeple too..but you will not be able to get rid of the back fire's....are you running a after market blow valve?

 

Dude, get a muffler. Running a straight pipe/open DP actually reduces your low end torque.

After that, get a tune and ditch the BOV if you have one.
