Hi all.

Recently bought a new GX sport.
Just before I got it it had a new exhaust right bacl from the manifold. But its tiny. Like miniture almost.(ref pic)

I went down to stainless exhaust fabs and got a few prices.
Now I know I cnt really gain much power or any of the gx engines. But donI go for just a new box? £220
From cat back? £420
Chap said if i had 2 cats i could remove one. If i only had 1 remove it and put a sports cat- (£175 ) so around 600 for all.

Or will it make any difference if I out a whole new one on?
It is restrictive but will it make any difference on my car?
What would you recomend?
Woeful exhaust
