however, with the Greddy Evo, i think that if your goin to do this conversion, maybe look into a catback with more restriction in the exhaust tip. i think i might be losing a little bit of my potential of torque because of it. the sound is kind of interesting. its not your typical import sound, not ricey in any way. it actually sounds more like an older VW bug than anything. lol... i guess thats why ZELL dont like it! haha. oh well... as for P's set up, i havent heard it personally yet, but i have been told that the AUTOMATIC trannies hinder the sound and performance of this set up a little bit... but that is somewhat expected with an AUTO.[hr]

I don't like it... at least not at low RPMs.
Automatics aren't THAT bad when it comes to sound for an aftermarket exhaust.

Rep Power: 0 when installing the header couldn't you have taken out the engine mount? then install then replace the engine mout yes or no because engine mounts do go out whenever and so they have to be able to be replaceable right or wrong? just wondering my friend brought this up telling me to just uninstall the engine mount then install header then replace engine mount can this be done or not?

Rep Power: 0 hey i just have a couple of questions... why is the 4-1 better than a 4-2-1? is there really that big of a difference? secondly, what is the best street-legal header to buy, one that is simply bolt-on with no need to cut anything (like motor mount) and with the factory o2 sensor locations?

best street legal header: i would go with dc sports 1 piece header and the random technology high flow cat. both will connect together b/c the random technology cat is a complete downpipe.
as for me, i'm going with the hp/or replica hp header b/c its not street legal, its 4-1, and the cat is simply gone. i don't mind cutting any mounts cuz i've done it before.

in 4-1 header, the pipes only coverged at one point meaning the velocity of air going through only slows down at that one point (more horsepower at high rpms, no increase of torque at low rpms). in 4-2-1, there are two convergin points (when the 4 pipes converged to 2 pipes and when the 2 pipes converge to 1 pipe). with two convergin points, the air slows down more than in the 4-1. (little increas in hp at high rpms, increases of torque in low rpms). i personally like 4-1, we need more top end power.

[hr]The cat is simply gone? ... uh... but it comes with a high flow cat... which makes it not street legal but for track use... [IMG]i/expressions/face-icon-small-confused.gif[/IMG][hr]

hey desi, i'm planning on getting the dc header first, and then im gonna save up again for the dc tcs cat-back exhaust... so when i get the header first, do i NEED to get a new cat back? or can it wait till i get the cat-back exhaust? p.s. thanks for all the info[hr]

Another couple things I noticed on my car when we did that install with OverTheTop:
1) Make SURE you install the springs that go between the new cat, and the catback otherwise you will get a horrible knocking noise when you use your brakes...
2) If you have a body kit, consider getting the hangers rewelded so that the exhaust sits a little lower because that day when we installed the system, the tip was actually touching my rear bumper and the friggen thing would shake the crap outa my car..not to mention you risk melting your bumper....
3) GET THE GASKET THAT BILL POINTED OUT IN THE DIY! Makes life so much easier with it in there....

answer: no. our headers, assuming you have an ex, are two piece headers. there's the upper half and the downipipe(the catalytic converter is on this pipe). dc sports just makes the upper half so it is complete bolt-on- easy to install. you can get the exhaust later. btw, i would personally get an exhaust first, basically b/c its a more noticeable mod than a header.[hr]

Rep Power: 0 I didn't really get a chance to drive it bacause I had to work, and I don't take my car to work. I will wait about a week to report anything performance wise because it takes a little bit for the ECU to adjust i think.

Rep Power: 0 He can get a new mount for $40.
NBPcivic, you do need to give it a little time for adjustment. About 500miles imo. Did it come with the sim or did you buy one seperately?
Anyhow, just let us know what you think of it after you have spent some time with her.
