ok fitted my decat pipe yesterday evening and made an anti fouler, first impressions were it sounds a tad better, having driven it around last night i can confirm it feels better at low revs and at high revs, seems to pull better, i am getting a smell of fuel though when i put it back in garage last night, think i will check the plugs today.

 

new pipes have that smell, decat cars also have a different smell to a cat car

 

It will smell of fuel

 

Yeah decat S usually smells of fuel, don't waste time investigating it!

 

what de cat did you use ?

 

That's placebo for you!

 

I did notice the throttle response is 'slightly' better, though it could be a placebo

 

Maybe it's me then.

I fitted CAI, Decat, single exhaust, removed sparewheel/tools and noticed zero difference.

Sounded MUCH nicer though and I like the single pipe look.

 

Nah your probably right.

You got a single pipe exhaust then Ron?

 

I removed all my Mugen exhaust / manifod / decat and only noticed a weight difference.
