exhaust system change.

ok.
Since my muffler on catback has gone dead, I'm going to replace it.
I will still have my tip but I will get one resonator behind the cat.
This is straight simple as I don't want to attract cops attention so similar sound will produce with this.
So I don't think there is anything else than resonator. normal pipe will be too loud..
Also I am considering changing the cat to a resonator. When I do this, I may get front pipe as well.
Is there any difference between brand ones and just normal custom work?
She said material is same and thickness is about 2? I can't remember....
The only thing is brand. The flow should be same.
Is there any main thing I have to consider?

i've decided to have front pipe and resonator then more like muffler type resonator and then tip
It should be around same noise level with what I have now or maybe quieter.
I can't wait till I find new sound
I hope it will serve me good.
Not too noisy, not too quiet. Just right

yea my exhaust sound is loud too, its custom work all the way. 2.5" down pipe, with a 3" cat pipe then all the way 3" with 3" jun muffler. could it be too free flow? cos it feels i lost a few hp with this system

Most people in the UK buy 3 inch downpipes...

Biggest power loss in your system would be the cat and turbo elbow (dump pipe).

Oh, and welcome!

[yewei]

so do u think i should go all the way with 3"? n probally with a bigger dump pipe? won't it result in power lose due to, too free flow?

Not unless I'm very lucky with my setup.

I'm running 207rwKW with a 3 inch downpipe, decat and HKS Hi-Power Silent (3 inch), along with a lovely wide dump pipe and tubular mani. Just under 1 bar boost. And being a Hi-Power Silent, its fairly quiet (84dB @ 4500rpm).

my setup is 3: all the way with one resonator, muffler and tip.
It's even quieter than before!! and more free flow.(but i still have a little restriction on muffler tho)
in cabin, I 'just' notice the exhaust sound but more like engine bay sound.
