Question will a centre de-cat improve my car?

I have an oe sti/prodrive exhaust bb and may be looking to fit a centre de-cat pipe from prodrive ,question is will this make much difference to the cars power and spool up etc or am I wasting my time with the more re-strictive sti/prodrive bb, and should go for a better make?

car is a uk 97 turbo

bit more freeflow... perhaps + 10 bhp in conjunction with a high flow panel filter

Fitted a centre decat to my old bugeye WRX, and it made a much better car. The most noticable improvement was the 3rd gear performance, which kicked in a lot earlier and gave much better accelaration. Best 60 quid I spend on her.

Exclamation

MMMM! just read the engine failure thing in this section and think I will probably give it a miss after what API Dave said about de-cats and air filters, I have a k&n panel filter in at the mo which may also be coming out.

Didn't he just recommend that you have the car remapped to suit mods that improve the cars breathing?

Decatting the centre pipe makes a difference, but not as much -by all accounts- as decatting the downpipe!!

Save up till you've got the money for both! That's what i intend to do. You'll also want to factor in the cost of a boost guage and knocklink to be safe

Hi

I have UK97 turbo and I went the full hog and decatted both downpipe and centre. I also have a prodrive back box. My car is alot more responsive since the full decat and has a much nicer deep burble from the exhaust. There is more power and torque lower down the rev range (circa 30bhp).

I was lucky to get both the downpipe and centre second hand for £150 ( power engineering T75 downpipe, magnex resonated centre). Car is also run on optimax
