As above guys,

My 02 sti prodive has a full decat and a rear jap style box from hayward and scott. They only standard bit left is the resonator section.

However i have a new centrepipe on the way without the resonator?

How much difference will the new pipe make sound/performance if any?

Sound - Loads louder!

Performance increase is negliable.

Regards,
Shaun.

Seriously, is it gonna be obtrusively louder?

I changed it on my legacy (single turbo the same engine as yours) to a straight through one and instantly noticed that the car was louder. Not too much so inside but slight. It didn't seem to make that much difference to the performance but I'd just fitted loads of mods at once including td05 and remap.

My UK car was 270bhp with a turbo back Magnex (which aren't too loud), my RA's about 320-330 and I've left the resonator in and it's stacks quieter.
93db at 4500rpm although the Fujitsubo back box is known to be quite quiet.

As others have said, large increase in volume, tiny increase in performance.

Edited to add:

If you do track days you may be over the Db limit as a few of the lads I went up with found out last season.

is it a nice noise?

i can handle it if its loud and nice but not loud and ****e

JTaylor

Define nice.

My GF wouldn't call it nice, or my neighbours (except the 19 year old a couple of doors up), my Dad would have, I might unless I was sat quietly somewhere!

Imagine the blub, blub, blub rumble you get now and let's say it's at about an eight on the dial. Removing the resonator will turn it up to 11.

LOL Cool,

I'll get it fitted and see what happens

Frayz, was that you I was chatting to on Sat at Southend when you pulled up by the casino, about your exhaust sound?? If so, as I said on Sat sounds damn fine as it is

I fitted a decat SS centre pipe and it was way to load, I then fitted the PPP resonated pipe and it was much quieter even than the standard catted centre pipe and there was less resonance in the cabin area so imho a resonated decatted exhaust is smoother and quieter than the standard one. When used in conjunction with a louder back box. I much prefer mine now than when it had decatted DP standard mid and T75 BB now it is full decated and sounds better as it is resonated.

Yeah Dave that was me, sorry i didnt realise exactly who you were at the time.

Well ill fit it and see what happens, if its not nice then i'll swap it back. It does sound really nice at the moment, but more than anythin i dont want a mild steel bit in the middle of my exhaust lol.

We'll see

It's really really easy to swap them so at least you won't have lost anything if you don't like it. It's 4 bolts with nuts

Yeah Paul, thats one good bit about it.

Only wheels, springs and mapping to go before i start to feel like its getting somewhere lol
