Like I said above mate, the 60RS should pass for track day, 60RR is not much louder, slightly quieter than Spoon N1, I think some people have had issues with N1's at track days, but it largely depends on what size collector you have on your header, are you running a decat, using a bung...etc?

Try google for a more specific answer regarding the 60RR and db levels :nice:

rs db reading 6k at standing is 93 i know this for a fact as i have one and thats what it read after our moring sessions at snett and thats with a high flow cat id say if you had a rr and wanted to do track you'd struggle ive heard the rr on a dc5 at a rolling road day last year and it was far too loud on full chat!!
 
looks good this. if more apply and the price drops a bit im down.
 
i would like to put my name down on a 60rs pending sale of my exhaust and as long as it is a full system from manifold back i have put my current exhaust up for sale so heres hoping it sells quick to pay for this
 
sadly im going to have to pull out of this for personal reasons :( gutted but ill keep you updated closer to the time

you may have seen the double can exit system

they are quite a bit more expensive than the single for obvious reasons

they do go for around 1800 pounds

Will keep the prices updated, but like I said in initial post, no guarantee of prices going down much more, Stainless Steel prices are already a bargain as they include shipping and import duties.

Like I said before pal..... it is a CAT BACK system, consisting of a B PIPE and MUFFLER, you can bolt it up to your existing cat/decat providing it's the correct fitment, easy way to ensure this is get an adjustable decat! :nice:

Is there any power difference between the rr and rs? Im looking a 70!

I'm sure there will be benefits and drawbacks between the two. 70RR is obviously larger diameter, better potential for power gain providing you need the extra diameter, which is dependant on mods etc, same argument as if you were to bolt on a 3" system to a stock engine, likely loose power due poorer flow and lower exit speed.
 
With doing the k20, guys worthship a good flowing 3" system. I might have to go for the RR. Anyt prices back yet for them?

Josh, do you know if there is any power difference between the 70 rr and 70 rs?

Just replied above mate :nice:

Between the RS and RR, I think there will be potential for small power gains due to it being a more free flowing exhaust, however I don't have any figures to show. It will also be a hell of a lot louder, the 70RR is LOOOOOUD :D
