New H&s Cat Back System Fitted And Wow !

[D19AKO]

Had the the system fitted on wednesday and its is monumental.....

If i am honest I dont know if I can live with it ! Its soo aggressive and the noise at low speed is a bit excessive for me... So there will be an embarrassing call tomorrow to H&S to see if anything they can do to drop the noise levels below 2500rpm./generally.

Anyone else had this issue or is it just me !

Let it run in for a few months. Carbon build up quietens it. When in started mine for the first time I thought I had made a mistake but I love it.

Sounds epic!

You'll get used to it - I believe after a week or so it quietens down a bit anyway.

Certainly is, by far, the best sounding car I've ever owned :-)

Had mine done over a year ago and at the time I too thought Wow, that's noisy. Driving back from Essex around half of the M25 didn't change my mind. It is EPIC. Does it quieten over time ? Nah, but you do get used to it so it will appear to quieten down.

I called them last week to book mine.. but now might be selling it for business investmets.. feel sad to think about selling it.. by far the best ive owned.. in th wise words of Arnie.. "i'll be back"

but back on topic.. is the exhaust that loud? I watched stu's video and it seemed bareable hence why i called H&S.. on the other hand when u mess with the silencers your asking for noise... just enjoy it.. if its that bad.. tell them to fit the stock one back on after a few months

post some pics and video maybe inside the car driving

One persons loud is another persons queit. Cold start is loud after that, for me it's spot on. Very similar to a c63.

Gutted chap. You haven't had it long :(

[Ace8800]

Yeh im gutted too.. i defo will be back no doubt.. hopefully if all goes well i be back in a ISF very soon.

Still looking at options to keep her.

Quick update... Getting slowly used to it....love the growl but still unsure of the motorway speed the drone of the exhaust isnt relaxing after an hour or so.... Might go back to making it a single pipe system instead of a dual pipe system from the cats but will give it a month.

If you want it quieter maybe get them to fit a valve? The switch would be a blank on your console. You can then make the exhaust loud or quiet. Or, get a muffler added to each pipe? They may even have another option.

I asked H&S about having a switchable exhaust. They told me they couldn't do a system to quieten an already loud exhaust, you'd have to have a quiet exhaust and a valve to make it louder, if that makes sense!

Oh... Bummer.

I had an exhaust added about two weeks ago and have a valve on a remote to bypass the silencers. This makes it louder and deeper around town but gets rid of the drone at 70mph. I normally drive in the louder mode but it is nice to have a more muted sound for early mornings/ late nights. The note from the car is much improved , up to 4000rpm in particular, with a great burble under load. It is not quite as good a note as I had with teh Larini exhaust on my last car but it certainly makes me want to keep the Lexus for that little bit longer.

I found the Borla system a perfect compromise of more than loud enough on throttle, without being intrusive or droney on a cruise; it's actually marginally louder than the standard system when cruising.

[Stuno1]

Personally I done find the h&s system intrusive at all and my clips of pre and post when cruising show that there is very little sound difference. I should have used my db meter pre and post but didn't think about it at the time.

How mutch is supply and fit from H&S if you dont mind me asking as there only round the corner to me

[Stuno1]

It was 850 when I had mine fitted. I think an extra 250 if you want a valves system. I should have asked for commission! There must be 10+ isf's with their system since mine was first through their doors :)

[loolee]

Thats not bad atall think that will be a bit better than just a res deleate, might have to pop down see if that price still stands

[Stuno1]

I agree. Very reasonable considering the prices of akropovic prices for vag cars.

[Piotrek]

Stuno1, do you have some H&S YT clips that you could share?

[Stuno1]

Here you go :)

Just looked up H&S, are they in Basildon? If so, I'm only 5 miles away, may look into one too, looking forward to the meet, IF I can make it, trying to reshuffle things

[Stuno1]

That's the one :)

I was sitting behind you in my wifes white 3 series coupe on Thursday evening on the A23 and then down the M23, got to say, it sounded great from where we were:))

[Stuno1]

Oh .... Haha. You should have made me aware and I would have booted it for you :)
