ph1 exhaust confusion...

[ryan ellis]

I've done a search and can't find the answer I'm after, so hopefully someone can give a definitive answer

Early ph1 had the single lambda before the cat, late ph1 (like my Exclusive) have another after the cat... So, does that mean my KTR cat back system will fit ph2 as well as ph1? The KTR website has option for ph1 or ph2, and not 2 options for the ph1 like I imagined there might be if there were 2 different cats on the ph1... hence my confusion! Someone please put me out my misery and call me an idiot if I'm completely wrong!

Thanks, folks

Give them a call.

It's the cat pipes that are different I believe.

 

[ryan ellis]

Give them a call.

Sorry, I guess my question wasn't completely clear- it was also a general wondering as I need to know what to buy as a replacement- ph1 or ph2...

K-tec exhausts fit all 1*2's iirc.

They have a sleeve joint at the cat end which you can extend and shorten as required.

basically the phase 2 172 and twin lambda phase 1 172 systems are the same fitment, only the early single lambda phase 1 172 systems are different (longer)

THIS is exactly what I was looking for

Thanks, man!

+1 this man speaks the truth!

Thats why i got my Genuine exhaust for £40

Quick ques- when you say longer do you mean the cat on the early ones was longer, or the centre section is longer?

Looking at centre sections it looks like:

early 172s were 128cm centre section: http://www.eurocarparts.com/ecp/c/R...4f67ce9e0ff8e49f3fcc25cec7cfc8d5dd3615&000430

later 172s were 124cm centre section: http://www.eurocarparts.com/ecp/c/R...c41b7efd055ee1506e8036b3d00aaebed9cf3c&000430

If that's right and I have the cat with the extra lambda after the cat, I need the shorter centre section, right?

Sorry for being a dumbass, it's just awkward when you type in your reg and the parts site tells you contradictory parts!

 

[Coops Mk1]

yes as you say, its the centre section on the early ones that's longer as the cat is shorter. for yours with the 2 lambdas you need the short centre section as your cat is longer, rofl!

And just to confirm , phase 2 cat back exhaust fits later phase 1,s with the 2 lambda probes on the cat, or phase etc

Well at least you got to rofl at me, matey! Thanks for the swift reply- just trying to get the parts ordered up now- if I type my reg in, it says I should have the long centre section hence why I wanted to make sure... Raaaaaarrrr!! :banghead:

That appears to be the case, which should make selling my KTR exhaust a little easier

 

[Coops Mk1]

wasn't so much at you rather than at my attempts to explain being a bit convoluted

usually find parts finders on reg aren't great at the little differences like that, knowledge is power though so good call coming to the forums and hope you get sorted

 

[Diagro]

Well.
I can confirm that there is indeed a difference.

Tried fitting my new exhaust and turns out I was sold one for a phase 1 ! It's too long lol

welder to the rescue!!

A KTR exhaust? Was speaking to a guy at K-Tec today, and as Budgie says- the pipe connected to the flange that slides into the centre section can be cut down- no welding should be required

 

[Diagro]

Nah mines a genuine renault exhaust. Has to be welded unfortunately
