CGR Automotive 28 Report post Posted July 21, 2016 Introducing the CGR Automotive Stainless Steel GT86/BRZ Exhaust. We're going to post up some pictures of the development system and go into some real depth to make sure we're clear on the extent we've gone to in order to make sure this is the best system on the market. Back-purge TIG welded to Aerospace standards; How the tube is prepared and welded is the most crucial part of the job. Every weld joint on our systems is TIG welded, however the difference between a good weld joint and a bad one is chalk and cheese. There are other systems on the market that have been TIG welded but none to this standard. The way we weld and fabricate our systems mean the joints are far stronger while being light and having NO restrictions. We could talk for hours about the fabrication process and how time consuming it is (we will tell you if you ask as long as you promise not to fall asleep). Differences between back-purged and none-purged welds when fully penetrated; As you can see back-purged welds leave no oxidisation. V-Band fittings The CGR system is held together with V-band connections not only to ensure an easy fitting and removal of the system V-bands are lightweight, with an extremely positive connection guaranteeing a perfect seal every time without the need for gaskets. This is usually a technique used in the motorsport market that we have used religiously in our race and road car systems since we began building exhausts as they are the perfect way to join the various exhaust components together. Fully Customisable for Individuality When we originally began developing the BRZ system, we 3D Laser-Scanned the underfloor of the car then CAD modelled the exhaust that we decided to run from the over-pipe backwards, removing the secondary CAT. To get that classic Japanese style we split the system down the middle and added two slightly upwards facing back boxes that are visible from the rear of the car. We then incorporated where the tailpipes and silencers would need to fit within the jigs, allowing for unlimited options to be spec'd without seriously affecting the construction process by using modular jigs, this allow us to adapt to fitting different silencer and tailpipe options. By having the CAD on-hand too, if we have any special requests that would not normally be catered for we can verify the amount of room and clearance we have in the CAD for whatever request we have without having to see the car or make modifications on the car. Split Pipe/Y-Pipe The pipe which splits the single system into two halfs is made in quite a special way, instead of just cutting two straight bits of tube together at an angle to separate the gas, we actually cut mandrel bends together at a perfect tangent to the rest of the exhaust. This is a lot of work and is possibly over-engineered however this gives absolutely no restriction and means the gas flows perfectly equally through both silencers before leaving the car. We felt that the extra work involved was 110% worth it in order to make certain the system was completely un-compromised and there were absolutely no restrictions or "hot-spots" of exhaust pressure. We weld and pack our own silencers in house, so although they look small they are extremely effective as we pack them very well with quality packing. And finally, the tail pipes! We appreciate 5” straight cut pipes might not be everyone’s cup of Saké, so the tips are completely up to you. Tailpipes can be made however you like, slash cut, rolled in, rolled out, burnt, square, oval, whatever it is get in-touch and we can quote for it. Pricing; The way we're going to price the systems will be as following, there's going to be a standard retail price for a single system on it's own, a 15% discount on the groupbuy if we get over 5 orders, and a massive 25% discount if we get 10+ orders.The price will be a base price which will include the following;2.5" GT86 / BRZ Exhaust systemTwo rear silencers and one centre boxRace tailpipes of your chosen size (dull polished stainless tubes as pictured on demo system)Larger silencers and multiple silencer configurations can be spec'd, silencers can be removed e.t.c to make more or less noise.RRP £1135Groupbuy 5+ £965 Groupbuy 10+ £851 All prices include VAT but exclude shipping or fitting. There's probably a few things we've missed off but feel free to ask any questions, whether it's commenting on the post, PM'ing us, emailing or calling we'll try our best to get back to you ASAP!Thanks for reading, and hopefully speak to you soon www.facebook.com/cgrautomotiveinfo@cgrautomotive.co.uk01709 530871 3 Foulsmell, long-gone and Keethos reacted to this Share this post Link to post Share on other sites
will300 812 Report post Posted July 21, 2016 @CGR Automotive what is the current lead time for one of these exhausts? Share this post Link to post Share on other sites
bassett 48 Report post Posted July 21, 2016 Workmanship looks fantastic but if i was considering buying id be interested to see a video clip of the sound idle/ cruising/full throttle and if possible dyno performance . What options are there for exhaust tips have you got any pics of the ones suggested above? Can original tips be maintained? Share this post Link to post Share on other sites
Paul 442 Report post Posted July 21, 2016 Photos of different tip choices? Video or DB evidence for noise concerns? Cat options? Share this post Link to post Share on other sites
long-gone 152 Report post Posted July 22, 2016 Interesting. As others have said a little more info would be good, but a high quality alternative piques my interest. Share this post Link to post Share on other sites

CGR Automotive 28 Report post Posted July 22, 2016 Hi everyone, the video is here! Our microphone didn't pick up the sound as well as we hoped, so the video is quite quiet and doesn't really do it justice. Apologies for this and I hope it's still useful to you. The lead time is approximately 4 weeks at the moment @will300 With regards to the tailpipes, we don't tend to stock them as we make them custom to order. But we really can create whatever you like to suit your needs. The ones on the demo system are dull polished straight cut stainless 5" tips. If anyone wants to discuss with us what they're looking for we'll let you know if there will be any additional cost or not 2 long-gone and TTR reacted to this Share this post Link to post Share on other sites

Minion 132 Report post Posted July 22, 2016 I've got a TRD which obviously has the quad tailpipes on it. Would you be able to make something that would suit and if so do you have a rough idea on price??? Share this post Link to post Share on other sites

Would you be able to make something that would suit and if so do you have a rough idea on price??? Yes we could cater for quad tailpipes for the TRD bumper, we'd probably have to get the car in to check exits of the dimensions e.t.c if that's ok but it's not a big job to switch the tailpipes, would you just want straight cut dull-polished pipes like our other systems?

billdingo 14 Report post Posted July 26, 2016 Another question about if this can be done with cats? Looks like a lovely bit of kit, but wouldn't want to swap the whole exhaust off each year. (I could use a catted manifold, but they are much rarer than exhausts that can retain the cat) Share this post Link to post Share on other sites

HariboPenguin 116 Report post Posted September 30, 2017 @CGR Automotive Do you have any dB readings for these? Currently looking for possible replacements for my Milltek aka. Cracktek but don't want issues passing Bedford's low 87.5dB noise limit. Share this post Link to post Share on other sites

Currently looking for possible replacements for my Milltek aka. Cracktek but don't want issues passing Bedford's low 87.5dB noise limit. Is your car currently standard? We've had cars as low as 88db on a static test, drive-by is arguably more difficult to test due to there being so many variables but on a standard car there's no reason why we couldn't build something quiet enough. They're custom built to spec so if you say you want it quiet we'll build one to suit We actually have a couple of ex-demo/ put on the car, driven round for a bit to test the noise then taken off again in-stock if you wanted to look at that as an option, would save a little bit of cash too.
