Will this combination give me a CEL? My car is stock with a Turboxs RFL BOV & air intake silencer removed. I have couple of questions regarding this mod.

1) How much horsepower can i see and how quick will my 1/4mile be?

2) Will i be able to install it or do i need to haev a professional install it?

3) Can I get a cat-back exhaust down the line when i have more money?

4) Is this a good begining mod?

 

I just found another cheap uppipe by Gruppe-S for 139 shipped. Will this work with the HKS downpipe and will this combo be as effective as the other one?

 

also, should i get a nice muffler off ebay and have them put that on since i heard that i can hurt my exhaust since the stock muffler has a lot of restriction? or should i not even worry about it?

 

I asked this same question a week ago, seems like nobody can answer it.

I would like those combination,since it is cheap with big brand. However, some questions may arise.

Since after install HKS up/down pipe will be remove all 3 cats,so.....loud?stinky smell?

But I would expect to be 20 or 30 with 3" exhaust installed (like Greddy EVO- Quiet but great cat back!!)

 

i have hks up and downpipe. you will get cel from it, but you can get cel fix for it.

downpipe its pretty easy to install you can do it yourself, up-pipe is kinda hard takes more time.

i also have hks cf/ti exhaust, its pretty loud without silencer. you will smell alittle gas smell when you stop at redlight but not that bad.

hope this helps. here is the link for cel fix:
