Borla Unequal Length Header Review and DIY

[jwjknorr]

Opened her up hard last night for the first time with my headers. Had a amazing first date lol went home with energy. I have been very happy so far, but i have to say, WOW. On a cool night with winding roads, she pulls hard and no longer has a dip. I cant wait to tune her.

That's what she said.

One month checkup

It's been nearly a month since I installed the headers. With reports of warped flanges and exhaust leaks I decided to put my car up and check things out.

It makes sense to me that if a leak existed then black soot would be all over where the leak was. Looking at my engine, everything looked clean so I think i'm alright. What we did not do was turn on the car and felt for leaks.
We did go back and retorque all the nuts/bolts

Here are some pics from my one month

Do you happen to log any data? Just wondering if you have seen an increase in coolant temps? I don't suspect, but just wanted to see.

thanks again for this write up. used this and the grimmspeed diy to remove the exhaust.

as for removing the stock manifold, i removed the two bolts holding the bracket for the overpipe. manifold was able to come loose fairly quickly afterwards.

I installed a Borla UEL about 2 weeks ago with a defouler. As I was driving it the first day, the cel light came on and stayed on for about 20 miles. It cleared by itself the next day and never came on again. I put on about 700 miles since with no issues!

Hello, getting ready to install a header, was wondering if an o2 wrench was really required?

[kingscratchie]

The 02 wrench is helpful because it has a groove for the wires to come out from the sensor making it easier to tighten the sensor in a tight spot.

I just ordered a Borla header and read through the DIY (great write up!).

What is the torque specifications for the o2 sensors? Do I need to put antisieze on them?

I'm guessing this is a no, since no one mentioned it, but do I need a new gasket for where I detach the frontpipe from the catback?

Last question, do I need the pass-through socket that is shown in the beginning? Where do I need to use it for?

Thanks for the write up!

I installed this header by myself too. Pretty straightforward.

I didn't torque the o2 sensor, just tightened it snug. Antiseize is a good idea.

It's always good practice to replace exhaust gakset, but I reused my front pipe to catback gasket. No problem.

I don't think I needed pass-through wrench/socket that was shown in the picture.

Good luck! Removing overpipe/front pipe piece from header was a bit challenging.

Yeah, that part was rusted like there was no tomorrow. Took me quite a bit of effort to get those two nuts off. Was a pain in the ass.

Now that I have the Borla UEL installed. There's a weird sound when I accelerate. Kinda sounds like air is going out somewhere. Only when I step on the gas petal though.

I think I have that same sound.
Sounds like a rush of air? I only hear it at either certain RPMs or throttle position.
I didn't notice any exhaust leak while I was down there after installing but I'm going to check again when I get a chance.

Yeah, that's exactly what it sounds like. I don't think it's a leak, because if it was, shouldn't the sound be there even when it's idling?
