3inch de cat pipe
 

Im looking for opinions for what 3 inch decat pipe to purchase for our 95wrx impreza, we have a 3inch hks centre pipe with resonator leading out to tailpipe, so what will be the best to get the best performance/quality etc.

Looked at Hayward and Scott, Scoobyparts. Exhaustsuk and flea bay.

I need it to be able to pay and pick up not wait.

Cheers for all comments. Baz and Shaz :doubleup:

Saj has got a couple of hks open neck down pipes.
Make sure you get stainless, a little more money but will last for ever

Have pm'd him and I will wait to see what he says, ideally looking for 304 grade stainless steel with the bell/open mouth in 3 inch so hopefully he might have one. Cheers Martyn :doubleup:

Is your centre a true 3" or does it tapper to 2.5" ?

Re: 3inch de cat pipe
 

True 3 inch HKS as far as I know, good point though, will check tomorrow, thanks CJ

Re: 3inch de cat pipe
 

If it tappers to 2.5 at the down pipe end there is not much point !

Re: 3inch de cat pipe
 

If it was 3" then it would already have an after market down pipe.

Re: 3inch de cat pipe
 

Faney at RSR went to put the back box on as I thought it was 2.5 inch and he told me it was a 3 inch, thats why I had built what I have as a tail pipe, now im confused :brickwall:

Baz
I am prety sure i am right in saying if your system is 3 inch then it must have an aftermarket up pipe as all standard up pipes with cat in them were 2.5 inch.

:confused: Think you mean down not up pipe ;)

Re: 3inch de cat pipe
 

Yes mate ur right :whistle: thanks CJ

Re: 3inch de cat pipe
 

Just crawled under the car and looked, it has definately got the original cat pipe which is then connected to a 3inch HKS pipe by what looks like a flange. The down pipe is covered by heat shields bolted together if that sounds right?

Normally I would take it to friends to sort, but as they are over 150 miles away its all new to me as I moved down here:sos:
