Hi all!
I currently have a 6 year old TSL Thundercat down pipe, decat centre and Racebox BB. Now thinking about throughput and power, what benefits would be had from moving to a decat down pipe over my current sports cat?
Of course, ignore the obvious MOT aspect of it.

 

Be prepared for the CEL light to come on mate if you go for the decat downpipe?

 

Decent mapper will switch off the CEL as part of their remap.
Decat will release a few more bhp than sportcat

 

Sports Cat works for me.

Not much in it with a good sports cat and decat to be honest.

Good sports cat? Which make do you reckon? There are loads out now but who does the best ones?

 

I was told by a respected mapper that a sports cat can give slightly better torque readings, only ever had mine on a RR once with a prodrive sports cat in place, Has anyone else had there car on a RR with and without sports cat? Would be interesting to find out what any increase would be, But sports cat for me anyway.

 

Once modified, my car has always had the TSL Thundercat and so I cannot compare with and without

 

I have an H&S cat on mines and it's quality
