Irish ISF

Any exhaust systems going for an IS F?

Recommended Posts

Just wondering if anyone here has an aftermarket system they want to part with before I pull the trigger and buy one.

I’d think long and hard before buying an aftermarket exhaust unless it’s electronically switchable.

That's the type I'm planning on getting. Xforce varex system is my first choice. Did you find yours too loud?

Mines got that one on, previous owner bought it. It's completely fine, i'd even go as far as to say i'd like it a little louder to be honest.

It's quite loud on cold start but it's only for 20 seconds (or if you really dont want it to be loud on cold start just stick it in drive once fired up)

It’s not really the volume. It’s down to drone. All the after market exhausts will suffer from drone at certain rpm / load. Even the stock exhaust has a little.

 Some people don’t mind it others do.

Hayward and Scott cat back on mine, limited if any noticeable drone at motorway speeds. 

Don't confuse drone with exhaust noise which is surely what you are after or you'd be staying stock. 

Mine has done 40k in 3 years with that exhaust fitted, mostly motorway and lots of that with wife and mother in law on board who have never mentioned the noise at all. 

Quiet and sedate if you drive it sedately, a bit noisier if you drive or like a nutter. I agree with @scott-o if anything, it could be louder.

Totally agree with Northern Dan

Tiny drone on my Hayward and Scott on warm up @1450 rpm but disappears after approx 5 to 10 seconds,I love the way it sounds on full attack ,should of got it on sooner

I’m really interested in buying one of these H&S units, but can’t decide whether to get the X pipe or non Xpipe.  Any thoughts?

Also...

do people find an H&S makes an ISF harder or easier to sell?

Also...

My ISF doesn’t seem to always blip when I downshift, and I’ve heard changing the exhaust to H&S will accentuate these little aural treats.

I've got the none X pipe one but still have the secondary cats in place. It's great but as above i'd maybe have it a little louder to be honest so i think at some point ill get a section made up to remove the secondary cats (maybe small straight through silencers instead like the H&S center section).

They only blip over a certain RPM, i've got the exhaust and a K&N Typhoon on mine and the rev matching sounds incredible now. The exhaust provides more low down noise then 4k+ the intake starts to take over.

When i went to view my car i didnt realise it had the exhaust on and the cold start noise pretty much sold it to me 😂 luckily the whole car is a top example!
