the screemer down pipe looks vvv nice

Boxer Turbo

The one that I want the Race Exhaust, does not take the lateral exit

GRD

One peice of additional info that is not on our website, is that we recently had the exhaust noise tested at scooby shootout and it came back as 98.5db @ 4500rpm which should be good enough to pass most static trackday noise tests + it also passed at Japfest Castle Coombe(not sure on result from that as just got a )....this was with a tubular exhaust manifold and GT30 turbo, so may even be slightly lower with an OE manifold and smaller turbo exhaust housing

Our latest Race exhausts do differ from the one in the picture slighly as have been modified to give even better wastegate flow

I am impressed with the design as seen on the web.
Not sure you need the screamer pipe really, but the race pipe looks very good to me.
I have battled recently with exhaust systems on my Hillclimb race car and I was not aware of this product (I may not be alone GRD!).

I know that there will be good reasons for the cost, but it is a lot for a non cat system, but it looks a nice quality bit of kit!

Make no mistake though that a noise level of 98 db is very very track friendly.
How did you GRD measure that?
On a hillclimb event (very strict on noise) the level is measured at 2/3rds red line rpm and with the meter 1 meter away and 45 degs from the exhaust outlet.

The problem that I have, in Spain as the lateral exit sees the police me, kills to me!!! For that reason I have to put a Down pipe of the first photo.

The cost is relative to cost of manufaturing, but we do feel its worth it as the quality is 2nd to none, the results we have acheived on them have been higher and the system lighter than any of the other 3" exhausts we supply from other manufacturers....only downside is that the angled exit back box is not to everybodys taste, but we are looking to offer the option of a 'standard' looking stait exit backbox at some point in the near future

The Screamer pipe Drag exhaust is more for our 'extreme' customers who just want a system as loud as possible, we know full well that it may cause issues with noise testing and we always make customers aware of this before purchasing!

Im not 100% certain how noise testing was carried out at SSO, may be best to drop Webmaster a PM and ask

I have used GRD for both 4 wheel alignment and general servicing in the past - and have always been impressed by them.

I am now booked in for a GRD stage 1 package on my 2005 Sti and have to say that their race exhaust really is a work of art (the quality is awesome) and feels light as a feather in my grubby mitts - looking forward to seeing the results they acheive

PS: Their stage 4 car is truly awesome

how much is the downpipe with the screemer pipe please

GRD

We can sell seperatly but it wont fit up to anything without modification as ours is a slip jointed 2 peice system and nearly every other 3" on the market is 3 peice with bolted flange style joints
