Gti Exhaust Recommendations?

[davy26]

Finally got round to rejuvenating my calipers. Next, I'd like to have a more assertive (but not silly!) exhaust note.  Would anyone recommend, (from their own personal experience), just a plain pipe to replace the centre section please? (And any known-good specialist workshops in the South East for this).  Thanks.

I've got a centre silencer delete currently albeit not a very well executed delete! Previous owner just cut out the silencer and put a metal sleeve over it, the pipe doesn't blow but I'm personally not a fan of the noise. From this experience maybe getting a Cobra backbox or any other aftermarket backbox and centre silencer may sound a bit better! Loving the callipers btw!

All these ideas about deleting silncers and making your machine noisier doesn't give you any advantages. The reduced back pressure actually reduces low down torque for normal driving, if you keep the stock cam timing. 

Unless the engine is always running well above 5000 rpm (like on track), the power gain is at the most only about 1-2hp. Running a car with an almost empty fuel tank and slightly higher tyre pressure will give a much bigger advantage...

The stock cam timing (overlap and duration) is factory designed to run with a stock exhaust.

II don't think David is after any more performance,he just wants a bit of a raspy tone I'd like the same.

Exactly right Andrew.  I'm lucky enough to have driven a great many sports/performance/supercars during my working career and nowadays find the Gti quick enough for my purposes on public roads.  However, all the recent activity around hybrids and electric cars has concentrated my mind on the unpleasant fact that the demise of the IC-engined car culture with which I grew up and have enjoyed for decades, is now a forthcoming reality, not just something theoretical, which we hoped might never actually come about. And, to me, a big part of enjoying cars is the way an engine responds both in terms of performance and the noise it makes. So I'd just like to hear my Gti emitting something a bit more fruity!

That said, one of the things I most like about owning a Lupo, as opposed to the Up Gti I had planned to buy, is that we have a 4 cylinder, atmospheric engine with good throttle response and a range of characteristics which can't be matched by a little, turbocharged 3 cylinder.

I guess I'm in a good position to comment on this! I have a Janspeed cat-back exhaust on my Lupo GTI, not the huge tail pipe version either, exhaust note is perfect, not too loud that it gives you a headache, but loud enough you know it's there. The bore is the same as factory so it doesn't damage any of the back pressure you need, the fit was perfect and was worth every penny of the £350 I spent buying it.

I also have a 2019 Up GTI in Tornado red, to say it has no character is doing the car a huge discredit. Sure it's no Lupo GTI, but the car has bagfuls of charisma and I'm loving every drive out in her. Handling is fun, performance is more than adequate, and I'm hoping to remap her soon for around 140ish bhp, plus with an induction kit from Forge Motorsport, I'm hoping for 145-150bhp, which is more than enough for a car of it's size. I highly recommend it!

Thanks Martin, that's very helpful.  I looked into Janspeed a few months back and at that time it didn't appear that they were still making for the Lupo.  I will try again as I believe theirs retained the central, twin tail pipe configuration which, to me, is an essential part of the Gti's distinctive 'look.'

By the way, I didn't say the Up! has NO character, just that I feel the Lupo has significantly more.  I had two Ups and liked their convenience, efficiency and quality.  But I do feel that VW almost went out of its way at the time of its launch  to make ordering a Gti  for a reasonably timely delivery date almost impossible - and I still feel it very poor that for months on end it was impossible to get a demo in my neck of the woods, (East Kent;  edge of the earth I know, but there's a rumour that we're getting upgraded to double-speed dial-up Internet next year!)

Look into custom stainless exhaust, you get exactly what you want, price isn't that much more than off the shelf
