Is there such a thing as a road side noise test the police can do? Im looking at getting decats for my na zed but its loud at the moment and I dont wan't to have problems in the future. Now it might just be me but my car is very loud and sets car alarms off when I drive past in town now so if its get louder :lol: My m.o.t station told me that the police can give you a fine or make you change the exhaust if its too loud.

 

Is this right?

 

 

Also will the japspeed decats fit a na auto zed? I remember something about them not fitting in the past

 

 

Cheers for any help

I have an N/A auto( soon to be manual) I had the japspeed decats and catback. I found the decats a little loud, so bought the decats with silencers from the zcentre and was a little quiter, especially inside the car. It passed the mot no probs with noise.

I have since got rid of the japspeed catbacks and now have a mongoose fitted, much quieter and a nice sound.

 

Now the japspeed fitted my auto fine, but i sold them on to maz jones and he couldnt get one side to fit on his auto, so i would say they fit a manual much easier, but thats just my experience.

 

If you are looking for a little quieter set up, i would get the decat pipes with silencers from the zcentre for the little extra money.

To be honest I love the car being loud :lol: Just had a quick look at the zcentre ones and they only fit manuals. So looks like it will have to be the japspeed decats and hope they fit. Is it the year of the car or something like that makes them fit some auto and not others? Also did you notice any improvement with them fitted?

 

 

Im worried about the noise problem as I don't want too spend money and time fitting them to get a fine the moment I pass a police car.

Mine is still an auto and they fit, you wont notice a great deal of difference in performance without other suporting mods, air intake etc. To be honest, i felt it went better left well alone, stock, but thats just me lol.

I only got rid of the cats at the time cos one was rattling, so had a knackered cat, it still passed the mot though.

If you want to save a few quid, you can gut your cats and keep the pipes you have.

i know of 3 Z's down here that were pulled over by the police who tested for noise and all failed!!

 

dan.:biggrin:

Sounds like I might be better off getting the ecu done like I planned and not bothering with decats. If theres a chance I will get done by the police and they might not fit :yes:

 

Cheers for the help :thumbup1:
