MK5 Resonator Delete...

[Diplomat]

Anybody done a "resonator delete" on a mk5 gti ?

Pros/Cons?

Is it a MOT failure?

Cheers

By resonator do you mean the noise generator pipe as found on the edition 30?

Hi - this appears to be something you can do on 'standard' mk5 GTIs...

What/ where is said resonator?

What/ where is said resonator?

Midway through the exhaust system (approx under rear passenger footwell) sits a box - to increase the noise, people (mainly US based) cut this out and have a non res pipe welded in.

If you look at aftermarket systems, such as Miltek, you will have the option to go 'res' or 'non res', and two pipes are supplied in the system. Pick you're poison: 1) Loud, or 2) Louder

Ah....I already have milltek non res!

Thanks Gareth - I wasn't 100% sure about what the exact process was apart from knowing something was taken out and it made the exhaust louder !

For those who don't want a stage 2 remap or pay for an aftermarket exhaust, I wonder if this is a cheaper alternative ?

I guess it boils down to what you want from your car. For a bit more noise, a resonator delete and/or a backbox delete are relatively cheap and cheerful options, and can sound a bit better than standard.

However if you're plannng on tuning at a level more than just a remap, you may as well get a full TBE system, as the standard pipework will eventually become a restriction.

Has someone had this done to there car if so is the sound any good.?

I've just done mine today. It's a HELL of a lot louder than it was. Maybe a bit too loud, I havn't decided yet. It sounds good under load but makes a funny noise when you change gear at lower revs. I'm gonna see how I like it for the minute but may end up putting a small silencer back in just to make it a little less noisy. Quick video for ya, sorry it's crappy phone quality but it'll give you an idea.



This was about 30 mins after I went for a drive to test so you could class this as a warm start. It was alot louder when cold.

plus your still running the stock exhaust meaning you wont make as much power than a full tb due to the width of the pipe.. i think stock is 2.25 and most aftermarket pipes are 3" meaning better flow

Has anyone deleted the resonator on their edition 30?
Thanks

I always thought it wasn't a good idea to take the resonator out as it makes the inside drowny so i booked my car  in for a back box delete next week

It will drone like hell   

Down pipe & sports cat on OEM system will give more power and sound better.

Pre-cat delete gives a nice burble too.

For outright noise, a cat back exhaust is required

I'm pretty sure it drones with a resonator delete not a back box delete I'm also getting a pre cat delete before a remap
