(T) 55S 1.1 exhaust makes sporting faster??

You may find this mad...

I bought a universal twin DTM backbox for my sporting which eventually didn't fit, unfortunatly the cow boy who tried fit it knackerd up the entire section from the cat back! Without wanting to spend too much again (fiat wanted £380 for new cat!) [V] i bought a second hand cat and rear system, which turned out to be for the 55S. I bit the bullet and got a mechanic to fit. Result! More responsive than ever! It flies when you hit the gas hard.[8D] Altough it's quiter as the silencers are smaller.;) I was gonna buy a Peco cat back system for £160 delivered.....

Is it gonna be worth it? Want a better sound but can't see it being faster than this? Anyone got a Peco cat back that can help??

Cheers.;)

Theres only one lane....
