Exhaust system advice needed (2005 STI PPP)
Hey folks,
some exhaust parts are starting to look a bit sorry so I’m thinking starting replacing and trying to improve it.
Currently it’s the 2005 STI PPP set-up with non-resonated mid pipe and a S202 back box, all 2.5 inch.
The sound is heroin, maybe a little on the loud and raspy side. It does drone a little on the motorway.
Would a resonated mid-pipe help quieten and deepen the note a bit? Any noticeable power loss with that?
And about the PPP cat, are there sports cats that offer better performance still passing mot?
Something like this for example:
http://scoobyworld.co.uk/catalog/pro...oducts_id=3396
I want to keep the S202 box and a cat that gets me through MOT, other than that I guess I’m trying to balance performance with not making peoples ears bleed.
Any thoughts and advice would be much appreciated!

You should already have have 200 cell I think it is sports cat with PPP setup. Yes resonated centre pipe will reduce cabin drone.
The downpipe on scooby world doesn't state if it's 100 cell or 200 cell. I have 100 cell. And pain in bum to pass mot. Needs heating up so much.
I would just keep your system and swap centre pipe. Will reduce exhaust noise and slightly performance. But nothing you'd notice I wouldn't think.

Yeah, that sounds good. A flange on the second cat delete pipe has mostly corroded away so I would replace that, too, that’s why I was considering getting a one piece (cat+cat delete pipe) item if there’s any performance benefit.
Who makes good stainless parts? I’ve seen H&S makes a center pipe with a long resonator and Cobra makes one with a shorter resonator. Any ideas?

You could probably have a new silencer and pipework bought and welded in for around £60

That’s a good option. I guess they could even cut the bad flanges off and weld fresh ones on. Think I’ll just order a new one or good condition second hand, it’s not gonna break the bank and it’ll be easy to fit.
Thanks for all the good tips guys!
