Well I finally decided that it was time that I needed to get rid of the nasty U-bend. I had exhuast shop take a look at it and there going to be putting a straight pipe threw it that there going to fab up themselves. Guy told me that the 02 sensor being on the side would cause a real big issue with snow hitting the sensor and killing it. I just said that shouldn't be an issue and told them to set up a time for me to come in. The guy tried to convince me as well that I wouldn't notice ne gains at all from it. I think with the mods I currently have this will contribute well so we will see thursday. I dont think the sound should be much different but im sure someone whos gotten the u bend delete can pitch in and talk about theirs..

When I did my custom cat back I had them bring the 2.5 pipe the whole way up to my cat there in deleting the u-bend. They put the 02 in at an angle not the whole way on its side.

i wouldnt know i did downpipe with ubend delete all at same time...

i wont be doing a downpipe and even if i did it woulda been with a cat

Tell that exhaust shop guy that o2 is not needed anyways, it only detects cat in-efficiency.

Then tell him to try and blow a golf ball through a garden hose and ask him if it would be easier with a larger hose. This is basically the same thing. It's a bottle-neck.

I think I may just bring that up to him when I go there thursday.

You're not gonna really feel that much of a difference

Wasn't planning on it. Just like every other mod I have its just a breather mod. Just building up the car one step at a time. It's just sad that appearance had to come first:( Feel almost in the same boat as Palsut, and we have similar color cars:(

Good attitude. I just didn't want you to have your hopes up for something big. I would go DP at the same time, but it's your car.

Never thought it would be a big gain. I just know I want to get rid of the U but with my current financial limits I can only afford having the U bend deleted which im getting a good deal on cause hes using stainless steel on it and installing for $80. Of course you know how the mod bug is, when it bites you just gotta have it, and well I don't think I have the financial maturity to save up enough for a downpipe. It's quite sad but at the same time true, but then again I am a college student and money is hard to come by sometimes.

Trust me man, I know.


And I know all about the mod bug.

All to well

$80? Ouch.

If I were I would save it and put that money towards a dp.

Is there an advantage over getting a downpipe from the u bend delete besides that of a new cat? If not I think the having the straight tube going threw would be just as good..

Yes big difference even with Cat.

Your OEM DP is a hair over 2" id. Where as the 2.5" is a full 2.5" id and the three inch is well...


The OEM is double walled to lower noise output. It's really pretty obstructive.

For power gains wise a full DP with or without cat is your best bang for the buck mod.
