best back box/muffler for the 1.4

[royal206]

Hey, recently picked up a 2002 206 1.4 petrol. A bit sluggish, but surprisingly zesty for what it is. I did some air intake work, and I plan to add a back box for more flow. I imagine the factory setup is rather restrictive. Any suggestions? Nothing super loud, but sporty would be nice. I have seen the Ulter system on ebay and it seems to be available and affordable. What do most people use?

Our CC doesn't use the 1.4 engine ... try 206info.co.uk

As Gazza said....

But in general terms:

I doubt the restriction of the back box is going to be that measurable to be honest. Restriction in the exhaust system tends to be a lot closer to the engine, typically any mani-cats and main cats will be your source of restriction.

Anything else is a compromise because any restriction points after the cat are going to be silencers - take them out and you are going to make more noise, no doubt about it.

You'd probably see best power improvement in equal length manifold and sports cat but on a 1.4 its probably not worth the investment to be frank as they'll be the most expensive parts to source and replace.
