Hi

I decatted the GTR last night, took off standard catylist and fitted a 3" internal pipe in its place

The car already has a trust 3" internal downpipe/s and what looks like a 4" middle and back section...again trust parts

So i went for a drive to work this morning expecting the exhaust that has been very quiet in the past to be a lot louder but nothing......sounds exactly the same!!!!:apoke:

I guess ill have to get some screamers then eh!

Anyone else had this experiance?, i have never known a car not to have a dig difference in sound levels after a decat

Could it be the backbox stifling it?

i guess it must be but with a 4" (or near that) diameter you would think it would be quite free flowing!

are trust known for this trait?
