Forged Rb26 Custom Exhasut Recomendations Please

[pauls]

Hi,

Late night post topic typo - exhaust.

I've got a freshly rebuilt rb26 capable of around the 600kw mark sitting in a z31 and its now time to look at a custom exhaust setup.

I'm running a precision 6466 Twin scroll turbo and will be going 4" pipe right through.

Street and track use.

Would appreciate some input on ideal exhaust/muffler/catback thats legal sound wise and performs on track.

Noticed one member using : 4" Dump to magnaflow mid muffler, 4" HKS Stainless catback to HKS Ti Muffler. (thought magnaflow did 3" tops?)

cheers,

Paul

You are better off just calling a exhaust joint for that kind of work. Saves chopping others to bits.

Have a centre muffler and rear oval muffler to keep the noise down. If you don't care about noise then just have a cannon

^^^what he said. Ask around for a good exhaust shop (posting up your location will help in this regard) as some are absolute cowboys and will charge you heaps for a rubbish system.

I use AES mufflers, made here in aus (Wollongong) custom length, design, diameter etc

thanks guys.

Noticed some shops and their mediocre welding work.

My motorsport guy will create the exhaust and looking at 4" all the way, given his experience is in v8 track cars, was looking for input as to what mufflers/spec guys are using on their rb26's.
