Silenced, resonated or straight though Test pipe/decats
Hi all
Im after some experienced and knowledge on test pipes. I currently run the 75mm HKS Single with a 63mm resonated test pipe and will soon be going supercharged. Therefore i am wanting to swap out the 63mm test pipe for a larger diameter part so that it matches the HKS. Although i am currently happy with the noise of my setup i have read that the super charger will make the car louder so i was wondering what options i had while i am changing out the test pipe.
1) Straight through 75mm Test pipe
2) Resonated unit (Not sure what the difference in a resonator and silencer is)
3) Ask our friends over at Solid Fabrication to make me up a 75mm Silenced test pipe (They have confirmed they can do this)
Does anyone have any experience with having a silencer welded into the test pipe and will it be effective? i don't really want to waste the extra money on a silencer if it wont make any difference.
Or even better still is there an off the shelf part i can buy?
Thanks in advance

Not a Resonated unit, have read it messes with the frequency and back pressure..

Yes performance wise a resonated test pipe is probably as bad (maybe worse) than a HFC.
If you are worried about sound I suggest you fix it further down the stream where small restrictions cause much less troubles.
I'm not sure a 3" test pipe is the best choice either, stock collector is just over 2" (54,6mm) inside diameter so going for a stepped transition like you got now might not be that bad.

Thanks guys
As I've previously said i'm not that bothered about the sound level as i love how it is now; but as im going SC i thought maybe reducing the noise may be a good idea if it was possible. 2 birds one stone bla bla bla.
Ill go with a straight through design as it seems the easiest and most cost effective.

By the way, what charger are you aiming for?
