Exhaust Question R32 Gtr

[ls128]

Quick Question.

I have a R32 GTR with Garret -5s Turbos, some light head work, apexi FC etc - Just basic mods.

I have been thinking for a while of changing the exhaust and having it after the cat converter out the side behind the drivers wheel. (Yes, I'm aware it will be very loud).

Do you need to worry about having enough back pressure (being a turbo car).

Will it cause any other issues aside from the legal side of it on a road car? (Will have this exhaust on for track days/driving too from the track)

Thanks in advance!

Will it cause any other issues aside from the legal side of it on a road car?

Well it would be completely illegal... so yeah

[ls128]

Yeah I am aware of that hence the "aside from the legal side" comment

More so wondering if it will hinder performance or have gains..

[r32line]

Less restriction generally has performance benefits however I think you would be crazy if you drove it on the road like that. It would be horrible

[ls128]

Would most likely be a bolt on bolt off system for track.

So back pressure won't really matter?

Thanks!

unless your car is jacked up like a 4wd i doubt you would even have room
