Having some Equal length headers fitted to my 2004 WRX in the next couple of weeks or so, and was just wondering what the sounds like compared to the standard headers, is it noticebly louder and does it sound like a superbike on full chat.

Also the car has a sports cat downpipe, decat uppipe and non resenated decat midsection with GGR backbox, it sounds perfect at the moment it sounds quite on tickover and then over 4k rpm it howls, just hoping it isnt to loud when adding the headers.

 

The main effect, apart from a little more power, will be the loss of the burble. The deristricted nature of the rest of your system will keep it deep and rumbly at low revs, and it will scream at high revs, but the base engine note will be more like ordinary cars not a Scoob A heavy sacrifice for a little more power

 

the burble is what makes it a scoob i love the burble and wouldnt trade it for little power gain

 

i agree,i love the scoob sound,why dont you get some better headers that are still unequal.

 

i agree ive got eqaul lenth headers, all my mates have uneqaul,i miss the burble but it does sound lush going through tunnels flat out and its nabour freindly in the mornings.

 

Are you saying it's generally quieter?

 

a bit yeah. i miss the burble to as its the classic scooby characteristic - having said that mine does sound great in its own right on full chat!

 

yeh for instance my mate stayed at mine on the weekend i started mine to warm it up.my mate then started his up and the whole house was shaking but he has got 5zigen and ive only got haward and scott.but you couldnt even hear mine.

 

I thought the MY05 STI was fitted with equal length as standard and that has the burble still

 

my headers are far quieter than the original spec, much more neighbour friendly and that makes me VB. happy

 

They are still unequal. The exhausts are just abit quite.

dipster.

 

JDM imprezas come with equal length headers, probably why they are quicker standad then a uk spec car.
