Decat pipe or sports cat which is ovarall best

got a 2.0 ts

im looking at getting a decat pipe made from the same diameter stainless pipe to fit my car b4 and after mot's

or would a sports cat be better to buy.

i would say the decat pipe is more freeflow but would not have as much back pressure as a sportscat.

which would be better.

any opinions or experiences welcome

My decat cost me 60, I don't think you would get a sports cat for under 200. If money is no object, get a sports cat. But if money is no object, trade your car in and get a 3 litre.

TS engines don't need much backpressure, very little valve overlap until the variator kicks in... freeflow would be my choice but you need to put the original cat back once a year for a few days....

Very good, as i dont think my cat has much life left in it. Barely passed Mot and smells that lovely "caty" smell.
Cant afford sportcat, or even a standard replacement at the moment, so i might be beating mine with a stick if it collapses
Think i might make a straight pipe.

The guys that recently did my sportscat did mention that i could have a straight through section and if i let them do the MOT then i would have no problems
