how much noise do these produce

 

never heard of a silent hiper- all the hipers I've ever heard have been feckin' noisy

 

Would deffo agree there - Hipers are not quiet

Cheers

 

got an HKS on mine and its not noisey but my lass knows when im coming ,errrrr ive said too much

 

the new hiper is called a silent hiper and it doesnt come with a bung so just wondering how much noise it will make

 

Its the Brand new hyper which is called a Silent Hyper.

It looks a nice bit of kit but its not going to be fitted for a few weeks so i think he wants to know if anyone is running one with a janspeed downpipe.

R.B

 

mine is an HKS drager and i dont think its loud its just right so i doubt very much that the new silent hiper will offend the eardrum

 

Try:

Turn down the volume on your speakers and it sounds quite civilised, really!
You'd buy it just for the looks, though!

 

cheers for that
