4" inlet mufflers

[[SKYHI]]

Just picked up my 96 r33 GTR Vspec it currently is running a 4" exhaust with an AES 4" dump pipe, the car is so loud it's driving me nuts and I have ringing in my ears all night after driving it so I'm hoping others out there have a suggestion for a 4" inlet muffler that's not a cannon style that can bring down the db when the AES valve is closed

That video sounds like the dump valve is still open

ive got AES mufflers in my 4in exhaust and it’s very quiet (I don’t have a dump valve at all)

If you want a 4inch muffler check out SP Mufflers.  After some advice I got on here I reached out to them.

Made me 2 custom mufflers in 4inch in and out to suit my probably one of the few Cefiro with 4inch exhaust.

Super easy to deal with and it is super quite, maybe too quite.    They can make to suit you though.

No definitely closed I'm not sure if it opens up under heavy acceleration but it's definitely closed at the beginning of the clip
