CPR are proud to announce to the GTROC, the Full T304 Race Spec Exhaust System from CPR, consisting of;

  • CPR 3.5" Y-Pipe De-Cat
  • CPR 3.5" Centre Pipe Section with V-Bands
  • CPR Rear Exhaust Section
  • V-Band Clamps for optimum fitment/seal

Price: £1295.00+VAT





The CPR Rear Exhaust Section has been labelled a true work of art by GT-R Owners who have chosen to modify their exhaust system with the CPR Part. The stock exhaust tone of the original system has generally been described as being far too quiet, not a true and fair representation of the immense, highly developed 3.8 V6 Power Plant. Without creating excess noise and leaving the owner with an intrusive, obnoxious exhaust tone, we focused on providing an exhaust tone that represented the High-End Prestige Image they felt the GT-R now belonged to, amidst the upper echelon of exhaust systems of the Exotica Tuning World from companies like ‘Tubi’ and ‘NoviTec’.
With a <b>3.5” Primary Pipe</b>, splitting gradually into twin 3” Split Pipework, the physical size of the CPR System dwarves the stock restrictive mass-produced exhaust system. The sweeping Criss-Cross Pipework features all smooth Mandrel Bends, entirely in twin 3”, promoting superior exhaust gas flow. The design allows the use of long high efficient Bullet Silencers made in-house as opposed to boxes, to allow for maximum flow and noise reduction. This design of the bullets creates a very distinctive look for the CPR System. The final part of the exhaust system features elegant split equal length pipework of the quad 3” sections, finished with four Slash-Cut Mirror Polished 4.5” Outlet Tips, allowing a subtle yet high class aesthetic improvement over the cheap looking, add-on tail trims of the stock system.

The entire system weighs approximately 27kg, with the Front Y-Pipe weighing 8kg, and the Complete Rear Section 19kg. The stock system weighs 28kg. The CPR System is manufactured from Industry-Highest Quality Grade of T304 1.0mm Walled Stainless Steel.

The CPR system also features Motorsport derived solutions, including 3.5” V-Band Clamping, to join the separate exhaust sections together, as opposed to conventional 3 or 2 bolt Flanges that rely on gaskets and bolts to seal. The inclusion of a high quality Motorsport Grade V-Band Clamp ensures the best possible fitment and sealing between the Y Pipe De-Cat and the Cat Back Rear Section.

Compared to the majority of the Aftermarket Japanese Systems, the CPR GT-R System differs dramatically in its design and construction. The majority of Titanium Systems offered by the likes of Sunline, Amuse and Mine’s offer marginal weight reductions over the CPR System, but with drawbacks noted by CPR’s Engineers during their testing of various Japanese Aftermarket Systems, including Poor Fitment, Necessity in some circumstances to Remove Rear Diffuser Supports, and most notably, greater restriction recorded through the presence of smaller diameter pipework. The Racing Creation System offers customers a free-flowing and excellent fitting prestige product, at a reduced price compared to the rival systems (some costing over £2,500.00+VAT).

Noise Output for this System is 97dB at 4,500 rpm Static Test, and around 95dB at Drive-by, so you can be assured that your GTR will be able to run at all circuits for trackdays without concern of getting blackflagged for noise limit breaking.

Features

V-Band Style Connections throughout - No Gaskets, No Bolts Required! Motorsport Derived for superior seal, precision fitment and high reliability.




Large 3.5" / 90mm Bore Pipework for maximum unrestricted exhaust gas flow to support big HP applications.



No Lobster Bends here! 3" Mandrel Bends formed to provide the smoothest gas flow exit, superior to our competitors' designs


Our Y-Pipe in twin 3" merges beautifully with Mandrel Bends into 3.5" Centre, providing the smoothest gas flow exit, superior to our competitors' designs


Our fabricator and Dyno engineer spent weeks developing our Y-Pipe, position of the Collector, size and position for our Bullet Silencers were critical in achieving our goal. S/S Flexi's prevent cracking as experienced on many competitors Y-Pipes


Simple, sleek tail pipe design, 4.5" diameter, in the highest quality polished material illustrates marque of quality from CPR


Image beneath shows Sunline GT Y-Pipe (top) compared to CPR 3.5" Front Y-Pipe (below), showing our Y-Pipe not only features far larger bore size, but also additional silencing and flexible sections to prevent any cracking as commonly experienced with the Amuse Systems.

That is a great looking system Lawrence and having seen it in the flesh so to speak I can tesify to its quality.

I have a couple of questions though:

1) Most noise testing is done now at 3/4 of maximum revs which is 5250rpm on a R35 so how much noise does your system produce at this speed?

2) Why is the 2011 model system £200 more?

Hi Arcam,

1) at 3/4 throttle, noise is around 97-98db

2) The slight increase in price is due to material cost going up (we source all of our materials directly here from UK based Hygenic Grade Stainless Steel Suppliers to ensure the quality is high.

Thank you for your comment also as to the quality, we pride ourselves in producing exceptional hand built exhaust systems. All of our GTR Exhausts are built by one person here at CPR; Russell Fellows, who is extremely skilled and experienced at what he does.
