Decibel output of Mongoose cat back on NA?

Post by mr2tourist »

Does anyone know what the Db noise level from a Mongoose cat back on a NA @3000 rpm is?

Cheers

Don't know decibels but I had one and I wouldn't have had any worries doing a track day if that's what you are thinking?

I had a mongoose on a 2gr on the end of a 2.5inch y pipe, it recorded 97db at 4500rpm at Bedford. Only a little fruitier than stock.

I had a Mongoose exhaust on my 1st MR2, which was an NA. Didn't sound much louder than stock. Nice exhaust.
