do you lose torque with a decat

[VR IN HEAVEN 0]

Hi all I had a decat on my p reg VR6 obd2. when I fitted the pipe it felt like I lost torque but he car was really good on the m-way over 60. having looked at other posts on the forum I wanted to know If I will have the same problem if I put one on my new VR 97 model obd2. as Not sure if the problem was with my old car in terms of torque. Any response is much appreciated cos I hear lots of different things. I have even been told to chip the car to get the torque back if its lost. This all leaves me very confused?X2£$ Just want a little extra power with the sweet sound and no problems!

Thanks

i was told you loose a small fraction mid -range, but its hardly noticeable with my other modifications (albiet the stuffed front end)

really only a comparison before and after on a RR will tell you the truth. Cant say i noticed any loss of torque with mine ...

just look at this video :

but ive got a few other trick bits too...

You do lose a tiny but of mis range but nothing to worry about - I overcome this by fitting a 6 branch manifold which made the exhaust equal throughout and then it run like a dream.

I found with the VR's - a full exhaust system and Kiera Nelson 10mm leads makes the car more efficent and you gain performance throughout the range. Best setup possible!!

cool iv been wondering this, so what does a decat achive? couple of extra bhp?

so you lose a couple torque without 6 branch but none with 6 branch?

The standard manifold is slighty restricting the flow - the good 6 branch makes full use of the engine out put. You'll gain bhp in lower revs. The torque curve should be nice and smooth. I've used a few mani's and for the money the raceland one cant be beaten IMO
