Well hopefully you don't have the same problem I did which is my injen exhaust wasn't even welded properly and I didn't know it until the pipe came completely off of the flange.

 

Installed mine on Friday. Took 7 hrs to get it done. I didn't have to remove the coolant hard pipes or coolant but did have to remove the a/c pump to get at the driver side front nut. The only thing I can say is thank god for the swivel head 14mm ratchet wrench. That is the only tool I could not have done the install without. I will NEVER do that install again....my arms look like they went through hell.

 

congrats....so how do they perform?????

 

They seem to have a little more midrange torque and I was surprised how much louder they are in the higher rpm's than with the stock manifolds. Power seems good.

 

Delivery date keeps slipping. Mine is now 7/03/04.

 

installed mine on saturday, so i currently have DC headers, testpipes,japtrix ypipe and midpipe with stock muffler and it sounds like ****!!!, so now im debating on ethier puttin the cats back in or buying testpipes with resonators, or gettin the greddy sp2, any suggestions?

 

I have the DC headers, R/T Cats, Nismo Y-Pipe and Fujitsubo exhaust and it sounds Great. I would have liked everything a little louder. But overall I like the set-up.

 

yeah my delivery date slipped to 07/03 as well. Hopefully sometime they will ship.

Since you've gone this far add hi flo cats. This will really tune the exhaust. The test pipes are what make the exhaust sound raspy and loud.

 

I took my test pipes out and put my cats back in.....no more raspiness but is still really loud in the higher rpm's. Much louder in the upper rpm's with the cats than with the stock manifolds and test pipes. You're right with the test pipes, headers, and stock exhaust my car sounded like #@&#

 

im thinkin about just sellin the test pipes and puttin back in my cats, i plan on gettin the stillen s\c sometime soon and heard that u shouldnt run it with testpipes cause it will cause it to lean out severly

 

I called Summit yesterday to check status on my stainless header order. They called back today and said the manufacturer anticipates shipping at the end of August.

 

That's about the setup I'm going to do (except Crawford Cats). How much louder or did the tone change when you added the headers and Cats?
Thanks.

 

OMG

 

My expected delivery date went from 7/9/04 last week to 8/20/04 today i guess it's worth the wait to get them at half price.

 

same with mine, order 5/28 - expected delivery 8/20. oh well

 

Mine went from 7/22 to 8/20 today and I ordered on 5/29.

 

8/20/04....

 

i am going to cancel my order and go nismo....can't wait...must have more power....now....out

 

I think this is the exact reason why Summit racing is doing all of this..just to get you guys to cancel your orders one by one, so that they won't lose as much money on these orders.

 

I don't belive that for anything. I would stick it out, the money saved will be worth it.
