Is there anything special i need to know when i install this exhaust....????? i need all the help possible....

boostin247

Nope, not really. All nuts and bolts are included. Simply unbolt the stock pieces and put the new ones on. It took me about 30 minutes.

do you have the same exhaust...and what uppipe and downpipe do you have????

boostin247

Yep, I have the same exhaust. I got helix up/down pipes from Gruppe-S as a combo with the exhaust. Great fit and finish.

did you notice a diffrence with just the exhaust...i am looking at buying the HKS uppipe and downpipe but i heard some bad $hit about them....so i am looking around i have heard of helix and heard they were good....

boostin247

I installed everything at once so there was a lot of difference. Definitely gave my car some more power. I would steet clear of the HKS up/down pipes, there are a lot of other brands on the market that are nicer and/or cheaper. The helix are great for the price and performance. I've never heard of anyone complaining about them.

they heliz uppipe and downpipe have sensors in both of them rite... how do you deal with sensors...i am going to order the helix uppipe and downpipe soon and i want to know how do i install them and dont mess up the sensors...

boostin247

The uppipe, you'll just put the stock sensor back in, I believe it's just a temp. sensor, you don't need a CEL fix or anything for it. In the downpipe you'll also put the stock O2 sensor back in, if you buy from Gruppe-S they should include a CEL fix that you simply splice into the wires going to the sensor. Istructions are included to it's really easy to do. Just don't touch the sensor tips with your bare hands, I guess it can mess up they're readings.

I have heard some bad things about the HKS Upipe because it is not a flex one. I also have the Carbon Ti with the Helix up and downpipe, and I love it. It sounds awesome and adds about 30hp.

You will need a resistor mod for the Uppipe also, The EGT will be reading different temps because the cat is gone so it throw a cel. I don't know exactly want the fix is, but if you do a search here on i-club I'm sure you'll find it.

boostin247

You sure? I never installed a resister mod with my uppipe. I know that if you install an uppipe w/o a bung for the sensor then you have to install a resistor. Never heard of it with the factory sensor still in place though.

i did the resistor with my helix flex uppipe. I did have my car with just a uppipe and catback for a while, then sold the catback and got a downpipe. There is noticable changes with the stock downpipe and a catback
