3inch girth

It's not a huge concern, my P10 was stripped and very loud. The main thing is being to pass sound test at any circuit without hassle. I do like being able to hear the chunes on the motorway as well, can't play racing cars everyday.

There are things Alan can do to reduce the drone if its of a huge concern.

Being in Devon and hundreds of miles away it's not like I could pop over

Was more talking in Kevs case here.

 

[Kevin85]

Yeah, get your own thread.

I looked at 3" but the noise was the killer.

If someone could produce a 2.5 / 2.75 / 3" exhaust that works on 98db trackdays (proven), I'm there. Until then I'll bide my time.

Run a TDI North 3" exhaust on mine (with Toda mani) and it was 89db static test, after 18 month of track/race abuse its still 92db so no probs at an circuit..

Everyone also tells me the induction noise is far louder than the exhaust on drive by as well ! Boring I know but the Spoon system I had was 106db an I got black flagged all over as it was louder than Porsche 997 Cup cars when testing at Brands !

Drive by at Snett with 3" TDI North exhaust if it helps...

That's a good help mate. I had a look at the tdi system, but I think I would prefer a straight through resonated rear box.

Anyone got a custom 3" system with as many resonators as will fit?

i gained 191 hp when i swapped my DC sports system for a custom 3''

 

[Kevin85]

Gained 191hp!? That's quite an increase, is that before or after you calibrated the wobbulator to chime in time with the capacitation bridge?

 

[Darren4]

Thought I'd bump this lol, anyone else got a 3" exhaust there happy with day to day?

 

[Tuneboy]

Yes, me.

3" Skunk2.

With Tegiwa Carbon Intake measured 235hp on a dyno.
I also think that 3" will increase power, but its really loud inside, especially at 130kmh+
