Ive used the tech header installation and have done that but I also have the S-pipe which i would like to install. Will the s-pipe work with the stock exhuast? Is there anything special i need to do besides bolt and screw if i can use it with the stock exhuast?

 

There's nothing special needed, it's a direct replacement just like the header. Just be careful with the O2 sensor. I haven't heard anyone having problems with the O2 sensor on the s-pipe though, unlike the header.

 

Ok thanks. Now I got the 02 sensor to turn once and now it will not move either way. Should i just let some WD40 sit on it a while longer or did i do something wrong.

 

Soak the bolt in wd-40. Let it sit for atleast 15 mins and try moving it little by little. If it still wont move, I hate to say it but it might be stripped.

 

Now, i ordered a ceramic dc sport header for my tc, but not the s-pipe.. is that needed? And also wat are the chances of the o2 sensor being damaged during this process and where can i purchase another one if i have too???

 

No, the S-pipe is not needed, I ended up not putting the S-pipe on because I ran out of time but you will NEED an anti-fouler for the stock s-pipe so your CEL wont come on.



BTW, I got my O2 sensor off and I looked at the threads, and it looks like it was cross threaded into the header. I had to turn the bolt back and forth to get it off. But I got it off and back into the new one fine.

Now my car sounds like a ____ed off honda, I have the resonator and the s-pipe, and Im going to take my car to a shop and have them put on my resonator and s-pipe as well as finish the rest of the piping. Hopefully then is sounds better but if not Then Im going to get a new muffler.[/url]

 

I love that sound, it puts those honda's to shame!!

 

Now I have the resonator on with a full cat back exhuast and it sounds very loud and not as ricy as it use to. But in high gear I can tell the muffler isnt doing to well with the new exhuast. So I think im going to get the HKS Hi-Power muffler.
