DIY - DC Sports 4-1 header install w/ pics
Installed a new DC Sports header... Here are some pics!
What you'll need:
12mm socket
Breaker bar (for the bolt on the far right)
Socket wrench
At least 8 inches' worth of extensions
WD-40 or other penetrating oil
Replacement bolts in case you snap one (they can be brittle): Part 16 here
Torque wrench (up to 23 ft-lbf)
Knowledge of how to use said torque wrench
A jack and stands
A new donut gasket if your current one sucks. Part 14 here. See below.
Here's the stock setup, of course.
And with it off now. Unlike some people here, I didn't have much of a problem getting the bolts off.
I made sure to take care of the gasket!
Here's the old one.
Make sure you take the donut ring gasket off of it and put it on the new one. Mine ended up causing an exhaust leak, so I got a brand new one. It's part 14 here.
Fresh out of the box, it comes with the header, two vinyl stickers (white), instructions, and a metal CARB sticker for the engine bay. Thanks, Auto Anything!
There should be instructions in the box, but if you don't have them it's 23 ft-lbf for the top 5 bolts (I had to guesstimate the oneon the far right) and 16 ft-lbf for the two (pain in the ***) bolts holding the header to the downpipe. Don't forget the springs!
Here's a close up of it installed. Sexy!
And all together, now!
The CARB sticker. I thought this thing wasn't CARB legal though.
Unfortunately, what would have been an otherwise easy install was hampered by my own ineptitude. I over-torqued one of the spring bolts connecting the header to the downpipe. In doing this, it snapped so now I have an exhaust leak on the driver's side. Here you can see the offending bolt is in there. It's gonna be a booger to get it off next weekend.
Here are the two spring bolts. The one on the left no longer exists as you see it here.
Fortunately, the Honda e-Store sells them for $10 apiece, so I've already ordered another pair and will get them changed out soon. I'm already tired of smelling exhaust.
One again, the torque specs for the bolts are 23ft-lbs for the top ones and 16ft-lbs for the spring bolts. I was more careful during the reinstall a few days later. Since the downpipe was only connected with one bolt, it started warping. I recommend changing both bolts like I should have done at the start.
You can clearly see the springs, the new bolts and the warped old one here:

Good shape is all I need. I have an Lx so I was going to convert to ex setup with high flow cat for better flow. I'll keep an eye out for it.

Nice!
Any noticeable difference compared to stock?
I've just done a DX to EX Full Exhaust Swap and I wonder if this is worth it, performance, sound wise.
