Exhaust Question

[shaun123]

hey guys,

I recently bought a new car. I wanted to know if this system was a turbo back or cat back system, the end of the muffler says "HKS Hi-Power", also i wanted to quieten it down abit, is there anyway to do this without losing power?

There is also this weird connector that runs from what looks like a resonator or something and it looks like it goes into the cabin, anyone know what this line is?

The plug is the cat temp sensor - basically useless. Many threads on it.

Looks cat back to me

That resonator looking thing is your cat, and the wire is your cat temp sensor. All it does, i believe, is turn on a light on your dash when your cat is dying - i think

thanks for the fast replies guys,

so its definitely a catback system hey? damn.. i thought it was a turbo back since its got a massive pipe going up into the engine

how could i quieten it down abit ? change the cat ?

show us a picture of the pipe coming off the back of the turbo?

looks like its dump pipe back so far.. however we havent seen the dump pipe.

The 1st pic showing the Down and Front Pipes looks aftermarket to me.

Can you get another pic?

From memory the stock Down and Front Pipes look very thin and usually have all this metal plating wraped around it.

hey guys, just took 2 more pics... it looks like from the cat to the back its newer whereas the piping towards the front seem abit older

Why don't you get a tape measure out and measure it?

Or take another photo of the front pipe joining onto the cat and then the cat back so we can see if the pipes are the same size or if ones bigger than the other.

It looks stock, but just measure it to make sure.

ok thanks mate, will try to measure it

how can i quieten it down tho? like change the cat or muffler or do i need to replace the whole catback system?

Put a resinator in just before the rear muffler, but that will be restrictive.

Yeah you can replace the whole car back with something more quiet like a Nismo or Kakimoto or HKS, who make a Silent Hi-Power Exhaust System.

It has a quiet rumble on idle and give a nice roar on full throttle.

Its an aftermarket front pipe, but stock dump.

To make it quieter, you COULD butcher it and put in different mufflers.. But that would be killing a JDM goodness exhaust

Sell it and buy something quieter.. Trust PE2 arent as loud.

hey, thanks guys... looks like i might buy a GKTech Front & Dump pipe combo, sell the HKS exhaust and get a HKS Hi-Power Silent or something... hopefully its abit more quieter

how much KW do you guys think it will pick up after this setup

the dump pipe is the little stumpy 90degree pipe from your turbo which bolts onto your front pipe, this is still stock, but your front pipe is aftermarket probably 3inch, save your coin and just go for a dump pipe (probably cost u $100) instead of a dump/front pipe (in one) you should notice quite a difference in power as the stock 1 is f*kin restrictive u will see just by looking into it when u take it off. but then again this will probably make your car sliiiiiightly louder but much louder spool up noise from your turbo. and resonators wont restrict your system f all if its got the same inlet and outlet as the rest of your system.
