Lude Generation

I'm swapping over exhausts between my UKDM and JDM as the exhaust on the JDM at the mo is way too loud (74db on tick over)
I'm hoping that the Janspeed exhaust on the UKDM will be quieter, do I swap over the Decat or leave the Cat in the UKDM exhaust for extra quietness?

i have a janspeed system on my lude and it was cated but not that quiet. have put a straight through decat on now and in normal driving around 60db but when in vtec loud enough!!!

cat on for extra quite - having said that i had a ukdm with cat on and it was louder than my jdm with decat
i think its more about how loud the system is - from what dbo says it seems the janspeed system aint too quite with or without.

My de-cat didn't make much difference in the volume.

pushki, you have a decat?




try both. its only 20 minutes to swap them over....

i must admit i didn't decat for the noise but the engine feels a lot less choked without the cat. and now when i vtec in first and SLAM her up to second i get a nice 3 inch flame and a lovely POP
the cat takes away all the fun

1994 BB4!! I have my first MOT with it on in the next couple of weeks.

good use of the scared toss!

I have my MOT in April and don't know if I should de-cat it or not

Ammo. I say do it as your car is old and won't need to pass the emission test?

No I don't need a cat for MOT as it's a 1993 BB4

Just gonna take it out for a spin with the Cat on see what it sounds like, I need the Cat for the UKDM once it goes in for an MOT so I'll have to decat mine at some point anyway. If I don't like it it's only 6 nuts to swap them over.
