has anyone got any pics of a true straight exhaust and I don’t mean no box’s I mean straight from manifold to the rear centre exit race style
 
A quick search:

i think he means literally a straight bit of pipe from the manifold back. so going under the fuel tank and not around it
 
Kakimoto did a under tank set up. Few other makes as well. Nightmare to live with.
 
I bought a custom one that went under the tank once, never again. Wasnt low and was scraping everything. Not too bad if you run a fuel cell though because it can pulled up tight.
 
I might just get one made for track days

What part of the world do you live? Only, you wouldn't get on 99% of tracks here in the UK with an exhaust utilising 0 silencers. lol
Even if you went for something that follows the car's exhaust tunnel using minimal silencers, something like a Buddyclub Spec 2, you won't stand a chance.
 
I never said no silencers, I run at Knockhill in my v8 silvia no silencers never had a problem
 
I ran a buddyclub spec2 complete straight through, no silencers, backbox, nothing at 9100rpm at rockingham and castle coombe with no issues!

Some of the guys on here will vouch for me on here, ha good times.

Yeah your car is rather loud mate lol definitely not for the road
 
was this on a show day though? i find that most venues are far more relaxed with noise limits on show days than actual trackday events.
youd not make it on the track at brands, snet, bedford and possibly donnington with a spec2 on a trackday.
ITBs can set the meters off at brands!

Few occasions at rockingham were mimms and a few evening track sessions.
Castle coombe was a track session.
On all occasions obviously got sound tested.
Some of the guys at mimms rockingham got flagged for noise even the boosted guys but for some reason ive never had any issues.
To be honest i think ive always got lucky and they turn a blind eye!
 
i had an apexi N1 under axle exhaust. it was straight from the manifold to 1 slight bend just before the backbox.

same as this on the ek

Yeah the n1 is as close as a off the shelf as I could find under axel looks so much better
