Exhaust Options

[JimF]

Ey up.
Just wondering what options there are for a Ph2 172 catback exhaust that's available new, rather than having to scour the classifieds. Needs to be trackday quiet and preferably stealth type.
I don't think the PMS mates up to the standard cat so gets quite dear when you add the sports cat.
KTec - Are these any good? I know the opinions on KTec are hit & miss, but not sure if that is for their exhausts or just them as a company.
Direnza - Don't know if they offer one, but I don't want to use them.
Custom - If I'm paying close to £500, am I just best off getting something made up? Then at least its being fitted and is guaranteed to be quiet enough and not bang anything on the undercarriage...
Are there any more? Milltek don't have anything but they've been focussing on newer cars for a while now.

Reason I'm looking is I've replaced my rotting standard system with a cheap pattern part to get it through the MOT, and its making contact under the car, and feels slightly restrictive.

I've got a unsilenced KTEC stealth on my car with a decat, and I'll warn you now, it is loud! Ideally if you're wanting to daily drive it I'd go for a silenced one. The quality of it is really good, fits well with some fresh hangers and so far seems to not rusted. As always with KTEC it took ages for them to ship it out, but that's not surprising.

Piper is what you want, probably the best quality aftermarket stuff I've seen for a 172 - admittedly I've not seen a lot but I'm very happy with mine

I put a ktec stealth on mine. It has the mid box so is relatively quiet.

Why does yours hang so low?

Why does yours hang so low?

My centre exhaust mount was completely shagged so it was bouncing around everywhere, in that picture it’s most likely fallen out of the rear hanger which happened from time to time 😂

 

[leedsboy]

Granted mines a 182 but this video is of my Piper with silenced mid section still in but decatted.

Not sure what @krarl and @Louis had/have fitted to theirs but may give you an idea on the slightly different sounds.

Mine and @Louis sound in perfect harmony on this video. You just have to ignore the silly man driving backwards in the oooo yep mobile and the oil chucking s3 😂

 

[Udder Nonce]

I was a decatted non-res milltek system in that video. @porl can confirm it sounded fantastic and not loud at all during the Yorkshire dales drive.

 

[JimF]

Great info thanks! I might end up running a decat at some point but just want to get the stupid exhaust sorted for now.

I spotted this but didn't want to say

The car is stripped and caged and mainly a track car, but I really don't want to fail noise testing on track so happy to go for quiet options.

Looks like its Piper or K Tec. Admitedly the Piper system looks nicer. How come it has two different length flanged sections - for Phase 1 and 2?

Phase 1 has a longer cat than a phase 2 which requires the shorter sleeve.

 

[JimF]

Ah yep that makes sense then. I was confused and not paying attention whilst pretending to be working.

Been listening to these in the car and they all sound great, especially the first one! But I think that may be the loudest?

 

[chazza114]

This was a video I got of mine in France, hopefully it works.

Yeh, I can confirm @Crayola is very raspy and loud 😂

They're louder as they go into the floor unfortunately. Get a rear exit and it'll be instantly quieter.

I've got this exhaust on mine with both silencers! It's not much louder than the standard exhaust.

Mines a 182 manifold, decat into an unresonated 2.75" Ktec stealth

Do you ever take it on track?

That sounds great as well!

When it's not in bits yeah🤣

 

[ADS_V6]

Got a silenced piper back on my 172 cup and sounds spot on. Pms unsilenced is too loud imo and much prefer the sound of piper to ktec. Excellent build quality aswell.

 

[JimF]

Do you get away with the noise limits? Or do you have to take it easy past the meters?

I'm leaning towards the Piper one to be honest.

 

[Tea Nonce]

Nah always just given it full beans, your car has either got to be mega mega loud or a Honda to trip noise restrictions at 98db

I reckon mines about 95db at most

 

[JimF]

Ah that's good to know. I had a Subaru that used to set off car alarms so I'm a bit paranoid.

Avoid a PMS exhaust then. Mine sets off car alarms just reversing slowly off the drive 🙉 And that’s just my stock 182. Strangely it’s only 92dBs @5,500 rpm

 

[Andy P]

@JimF If getting the Piper definitely get the one with the centre silencer.

I didn’t and ended up fitting one myself. Without it the exhaust was just too loud @ Motorway speeds.

somthing badly worn in the front end of that Inferno, its pulling all over the road! Track rods/ends/bottom ball joints

talk steer that Martin with an eye

 

[Ph1 Tom]

A big single box system will pass noise limits. Adding a mid box will help you with drone on the way to and from the track.

 

[JimF]

Defo think its a 2 box Piper when I change. I've just got to fix the perpetually broken power steering pump again.
