The issue might be the angle or exact positioning of the bracket that mounts to the rear of the gearbox. My CES pipe has a different but relevant issue that comes from how it lines up with that mounting point. Basically being slightly off there gets carried down the line.

I suspect you will be able to make up an adapter out of a small piece of aluminium that will work to bring the whole thing own a little. There is a little flex in the whole thing so dont worry if you have to pull it down to get it to mount differently. For example, there are two holes so instead of lining up both you could line up the bottom gearbox mount hole with the top exhaust bracket hole and try that for starters.

thanks abo...... i fixed it today, it was hitting on the bracket bolted to the floor pan to stop the tailshaft hitting the ground in the event of failure, so i took the bracket off and elongated the holes and bolted it back up so it sits slightly higher now..... no noises at all anymore yay!!!

30 mins i find that hard to beleive....... anyways i got under the car this arvo and its not hitting up the front it is further down near the tailshaft centre bearing, its hitting the bracket that sits on top of the exhaust and under the tailshaft centre bearing. maybe pics would explain better. Any ideas on a fix????

No joke Ben :D Grey Imports fitted it up for me.

You do need to be weary when fitting any front pipe that when you are removing sections of the exhaust its possible to shift the rest of the system in the process which can result in the problems you have had.

As others pointed out its usually a case of trial and error and hanger/mount adjustment where applicable to get it spot on :D

hey blitz just out of curiosity what differences did u notice after having yours fitted???

Well, I had a hole in my original factory front pipe which sounded terrible, but once we fitted the new JJR pipe up the car generally sounds a whole lot smoother, with a nicer exhaust note and it seems to drive nicer also.

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
