Altima eBay Headers installed (Hotshot knockoff?)

Reduced ground clearance. I'm not slammed so I don't mind too much.:
Quick video
Cruising at 45-50 mph. Silence is golden
Partial throttle acceleration - typical daily driving
WOT
WOT from a dig
Within the next few days I will log some pulls with my EU and compare them to some logs I recorded at the track a few weeks ago. I also plan to go back to the track within a month to get some times with headers to compare to my most recent trip with the y pipe.
After installing these headers, my car is a lot quieter in normal driving than it used to be with the old y pipe and 3" exhaust. The drone zone I had at about 2100-2500 rpm is nearly gone, I can still hear a slight change if I listen for it, but otherwise I'd say its gone
One of my favorite parts, to an extent, is the cost.
Altima headers - $135
y pipe parts and labor - $114
Total spent: $249

Thanks!
I am nearly finished with these headers, last thing I need is a 3" gasket. I had a 3" test pipe made and a flex section installed today.
So far it doesn't seem much louder compared to my resonated test pipe, but I will reserve judgement until I drive around with it some more.

I didn't take it to a shop, a friend of a friend did the welding. I bought the flanges and mandrel bends from a local muffler dealer warehouse. I used the collector gaskets that came with the headers, and reused the oem manifold gaskets. I will be ordering the 3" test pipe gasket.

Time for round two on these headers.
I got my hands on some coilovers and rode around the the y pipe 1"-1.5" off the ground. I went to a ghetto tire shop to have some tires installed. Drove the car on a lift similar to the one below and the y pipe hit the hydraulic arm. Then I drove around with the reduced volume y pipe for a month or so until I finally got around to having a new one made a few days ago.
The damage:
I decided to do away with the flanges for this y pipe since they were such a pain to get to. This time around I used the flowmaster y merge posted earlier in this thread (part #Y214300). And two band clamps on the inlets of the y merge.
My cost for this y pipe was $106. I signed up for Amazon's credit card and they gave me a $40 credit which I used to get the Flowmaster y merge for free.

in for sound clips. Ive had this same idea mapped out in my head for months. What size pipe did you use for the "collector"?
edit: nvm found it. Is the header touching your A/C line on the front?

I need to buy a welder before I can do that
Which part? The two 2.25" primaries merge into 3"
I'll take some clips after I fix a minor exhaust leak. 3" collector.
No but its close, about 1/8" of clearance.

Nah I had to see what rpm fuel cut was at so I could extend the rev limiter with my emanage.

But cool work with the y-pipe welding. Even though the last one broke, I'm sure all in all this is still cheaper than other alternatives for header/ypipe

Right now I'm between a set of OBX V2s and Cattman at ~$500

Finally fixed my exhaust leak. I moved the clamps off of the merge and closer to the headers, soo much quieter now. Vids coming soon.

I think you need too do another one and use flexible tubing as a model and copy it to the T! Your transitions suck.....You've got big nuts but no juice....There gotta be a way to squeeze the U shaped tubing in there better than that!

The car isn't running right now. I'll try and get some by the end of next week.
I could probably run it forward and wrap an uncut 180* bend around the front of the oil pan. Yea its not perfect, but this one is WAY better than the first one I had. I do want to switch back to flanges on the y pipe since these clamps like to loosen up over time.
But until this y pipe gets completely destroyed and I learn to weld, I have no desire to change it. My major driving factor with these headers was cause they were cheaper than OBX, but after changing the y pipe a few times I'm $500 into these headers and do not want to spend any more on them.

i209.photobucket.com/albums/bb136/deviance105/h11389.jpg So these wouldn't fit? Cause these are with an equal y pipe already... are these v2s? Cause there's a version of 3.5 headers for the altima that don't have the equal y from obx.

3rd time's a charm right?
The loop on y pipe II was much to close to my lca and the heat killed the bushing. I'm in the middle of a bunch of other maintenance right now so I figured I'd fix the y pipe. I'm doing all stainless this time.
All I have done so far is a mockup with the 2" piping that came on the altima y pipe to see if I could feasibly get the pipe away from the lca. So far so good.
