A few questions i have about exhaust and manifold...

[Smc92]

Hey guys, i have been looking at getting a janspeed manifold for my k11, but what i was wondering, if i put the janspeed manifold on and then onto my current exhaust (which is just a standard exhaust) would it still increase power? And does the manifold bypass the first cat and straight onto the down pipe of the exhaust? I was also wondering if i put the janspeed manifold onto my existing exhaust, but took the 2nd cat out and put a performance back box on, would that increase performance even more than the manifold on its own or would it just make sense to buy a full performance exhaust system?

I was going to buy a full 2" stainless system but the car needed a full new exhaust to get through MOT (it had been on the car for 16 years lol) so i couldnt wait any longer and had to get a standard system because i couldnt afford the perfomance exhaust at the time, thats why im reluctant to replace the whole exhaust system when its less than a month old.

Thanks for any advice guys (Y)

i doubt if your 1.0 will gain much tbh scott (mine did,nt)

Will just make it sound nice when you're trying to find the rev limiter

yeah it would sound nice especially with a jap can on it as well

So you dont think there is much point then frank? Whats the best way to get a bit more gain out of it then do you think?

Ive still got a Frank manifold , Janspeed deccat and Sports back box to put on mine a real iffy set up i know but id be interesting to see if there are any noticable gains on my Super S !!!

Frankspeed manifold, standard first cat sportex downpipe to back box (Y) passed emissions without any problems :laugh:

Just got to find the time to get under and fit but looking forward to a more purposfull exhaust note (Y)
