Hi guys thinking of buying a pre cat for my 1.9 was wondering if anyone would say its a worthy mod. At 150/160 plus fitting its not the cheapest mod. Wanted to get views before I jumped and bought one. M currently running a Simota and crd2 red box (old one ) previously rolled 193bhp would the pre cat see as many gains as they state on manufacturers site.

You get more torque than outright power with this mod.

that's what diseasals are about. Its must about 20 ft-lb.

My bhp on a 1.6t went up by about 3 or 4. On the listings they said about 10/12. Torque went up 30 ft lbs over standard.

MMM scorpion say 10BHP!!!

I would be interested to see what the torque increase is then 20lb-ft?

 

[Telboi_Astra_SRI]

That's wht I mean a little skeptical about 10bhp that's a lot from a pipe essentially just waying up the price for benefits

I bashed the insides out my pre-cat, termed gutting, that worked well, just not as free flowing though.

Try that first.

Pre-cat down pipe is a must on the 1.9! Frees up the revs and some mid range torque.

Is it deffo noticeable tho pete?

 

[Lashed]

Yes. It's not as noticable as when you first slapped on your CRD2 but it definitely helps the car perform.

If you're not convinced, do what Nello says and remove the guts from a standard one, if you feel that makes a difference then a proper upgrade will only be better.
