Question about my stock exhaust and header

[burt]

any updates yet? But with an aftermarket header and stock exhaust, you wont feel too much of a gain. But if you save up a little more and put a cat back on then you should notice the gain of both a lot more.

you will need the downpipe to, the dc header is alittle longer then stock, so im assuming the downpipe is shorter to fit. it was pushing the DP by alot in order to fit. i just tried this yesterday and had to put my stock one back on.
so now on to the search for the downpipe for me
edit>> by the way i have a an A6 so 4-2-1

No updates just Yet I was replacing the O-rings on the rocker arm assembly and one of the bolts snapped while I was torqeing it down. Luckly it some how stayed together enough for me to get it out (hard to explane).
So I need to go get a new bolt then I will start on the exhaust and intake. Once thats all said and done I will start the body work with new front and rear bumpers, front legend lip and so on.

Wasn't there a difference of about an inch between the catalytic converter found on the DX/LX and the EX?

Ok I got the header and down pipe. Im not gonna be able to use my stock one due to it being a 4 into 1 design. My header and down pipe is now going to be a 4 into 2 into 1.

Damn that stinks. Now you gotta buy a cat back designed for the 4-2-1 desgin.

Im going to a shop to have them weld a flange to bolt up to my stock cat back.

Really?

So my WS2 cat back exhaust that I bought for my Accord that had an F22A1 (4->1 header design) is no good for my F22A6 motor (4-2-1 header design)? Explain please?

Do you not have a catalytic converter or a test pipe?

Why does everybody not want to weld the exhaust together? are you really gonna take it apart that much?

you can use whatever catback you want.

To each there own...Some people just aren't fans of welding the entire exhaust together.

you can use whatever catback you want.

That's what I was getting at.....

Instead of welding everything together, go to a mufflershop and have them weld on a few flanges. It makes life much easier later and isnt expensive.

whoops, I was thinking of something completely different when I was typing. Haha I didn't mean what I had typed. ignore that

But yeah you CAN use any cat back of your choosing.

I had to replace the whole thing due to mine being a 4 to 1. Also oxy sensor locations are different with header brands. Sometimes underneath close to flex pipe or right on the header.

[deevergote]

EX models have the o2 sensor underneath, and the DX/LX have it up top.
