Ok, i did a research on the different downpipes, 1 thing i can't understand , do u pay just for the name ? , Cause they look all the same , a simple tube, but the prices vary from 120 to 200 quid . H&S 190 HKS 180 Jap speed 140 quid, Anyone know the difference? Or as above u pay for the the name?

 

They do vary, there are bellmouth and twin dump designs, best one to go for would be a 3inch bellmouth type, beware of downpipes which start off at 3inch then taper down to 2.5inches, Hayward and schott, milltek, revoloution and TSL all make true 3inch downpipes

 

Killer what do u mean to beware of those 3" to 2.5" . H&S they do those as well , i think it depends what power u wana go for ,For your type r i gues u defo need 3" , anyway , again what would be the difference between them ?
Why should i go for more expensive one or not?

And i'm talking about open neck ones....

 

They taper down to 2.5" to fit a o.e. center pipe or 2.5" center section, if you can wait a few weeks you can have the magnex twin dump 2.5" downpipe which used to be on my TypeR for £50...

 

I've got one from japspeed, and i think yhe quality is pretty good. The one thing i don't like is cause it is very loud , too loud for me, that's why i'm searching for the differences between them, maybe they've been made from the different metal or smthn , just tryin' to figure out ....

 

There are 2 soloutions to that, get a bung made up by hayward and schott or buy a resonated center pipe...

 

I've got 3" HKS center pipe and HKS hi power 120mm back box for high power outputs which gives me a headake aswell, i'm just goin' now a bit more sensible route as i drive a car more often now, i'm not sure ,but i think my center pipe is resonated , but it still is f*** loud...

I would better go for another back box some smaller i guess. What have u got killer?
