I am getting the greddy SP exhaust system this friday and injen intake for $250 this friday.

1)Would it be better if i installed the system myself or take it to the shop? I have no clue on how to install the system, but my dad might. I've read the DIY section already.

2)Would it be better to keep the greddy muffler or purchase an apexi N1 muffler?

3) What should I spay on it to prevent it from rusting?

Thnxs in advance >>

hioctane, I asked myself the same questions. It depends on if you want to get into this whole car thing. These two mods are definitly the first, and definitly the easiest to do. Don't kid yourself, you're going to need someone there who knows what they are doing. Someone who has worked on cars before. If you dad has even the slightest experience, it should be fine. You'll also need a basic set of tools. The injen instructions confused me a lot when I read them by myself, but when my friend showed me everything, it's really simple.

If you know someone like this (ask around, you'd be surpised who is a car person) then do it. If not, then take it to the shop and ask the person to show you how to do it.

Is the apexi N1 just a muffler? If it is, I'd go with the cat-back greddy.

Clean out the inside of the tip of the muffler after you have run it for a few weeks (about a month), then spray a few light coats of high temperature paint. Black... unless you really want to look stupid. I haven't had to paint the outside, and I hope I don't have it. I like the bling.

Im not sure if you will have the same problem that I did but when I went to install my greddy I found that I had a second o2 sensor that needed a place to fit in the exhaust. So a hole wass drilled in the exhaust and a threaded washer was welded on so the o2 sensor could screw in. Other than that the only things you have to do is cut the bolt heads off because they are probably not going to just come off unless maybe the exhaust is hot but then thats dangerous. So you could check if you have an additional o2 sensor after the cat and if your bolt will come off. I dont know what kinda tools you have but if you can handle those two problems then do it. Exhausts are not hard at all but most of the time the bolts have to be cut off or drilled out. Good luck, hit me up with any questions.

thanks for the reply. I appreciate it. I asked my dad about the exhaust system thing and he says it's a lot of work, so I might take it to a shop. I have no clue what they charge for an exhaust system installation.

me and my friend modified a Prelude CAI to fit his probe GT yesterday, took us all but 20 mins to do, including the fabricating... real easy mod.
