rear box on exhaust

Recommended Posts

hello everyone. i have the sj supersport rear box on the s4 and i'm wondering how much louder it would be without a rear box as im thinking of replacing the rear section with a new stainless, there is nothing wrong with the sj rear section but as i have had the manifold and cat sections made i may as well go the whole hog and replace it, just wondering if its legal to have it without the silencer as i cant see the small box doing a great deal

It's Oogies turn to boogie

Mine runs standard manifold and cat section but with 2.5" straight through after the cat. That I put together myself with Jetex parts for a total cost of £80!!!!!

Whilst I am not happy with the 'type' of noise*, the volume is perfectly acceptable. Loud - yes, but not loud enough to make babies scream and rattle windows.

*plan to create a twin exit later in the year, same size tail pipes but will use a feed off the main exhaust with 4" pipe. The plan being to not disrupt the flow of gases (hence why I kept to 2.5") but at least give an echo chamber to deepen the sound

An unfortunate fascination with Lotus, and proper drivers cars.

All caused by S75 LCF back in 2002, a mustard yellow GT3, and someone on here's got her.....
