Yup hp tuners works wonders. If they fail me then ill out on my stocker lol that's why its still sitting on my balcony

 

No codes with my Hahn but anyone whp has a nose can smell there is no cat on there. . No emissions testing in FL so no problem there.

 

i have synapseturbo dp and i think it was well worth it

no codes... and my dad does the emissions on my car so i dont have to worry about it lol

 

get the hahn one !
pure sex

 

I agree. 3" catless Hahn DP, 3" Catback with no resonator and a Borla XR1 muffler. It is loud now.

 

SOUND CLIP!

 

If I can get a good video camera on thurs when I go to the dyno. . The only camera I have is a digital camera with terrible sound quality.

 

I'm still trying to figure out why LSJ guys comment on dp's for LNF. Are the DP's kinda the same? Totally different? Seriously I need to KNOW!!!

 

If you got a catted dp, would there still be power gains?, could I get a catted downpipe with a cutoff before the cat?

 

there wont be power gains because of our computers learn back feature....

totally different

good man good man.. i am in the same seat as u

 

If you got a performance DP (like CIA or Hahn catted 3") yes there would be a power gain over the stock setup. You could add a cutoff before the cat as well, I think both offer this option.

But if your considering all of that...I would consider this

Then just purchase the cat option and the straight pipe option.


As mentioned if your not tuned the car will work on detuning the power it gains to maintain 260/260

 

Removing the O2 sensor from the direct exhaust strem basically fools the computer. The computer is comparing readings from the pre-converter sensor and the after converter sensor. Moisture isn't an issue as long as the sensor is positioned correctly.

No coeds result because the computer records a big enough diffference from the front to the rear sensors.

 

soo im lost on ^^^

 

So you dont have any codes dp, isnt it catless??
