MCR Release Stainless Downpipes for Nissan GT-R

January 24, 2010 Comments off

It’s been a while since we’ve updated new parts from MCR but they’ve been keeping themselves quite busy. Recently they’ve released a new set of stainless downpipes for the GT-R that delete the primary catalytic convertors.

Built from SUS304 grade stainless steel, these weigh in at 8kg less than the standard pipes. They measure 70mm in diameter and go for around 105,000 yen in Japan.

Harman Motive New Parts Released: Downpipes, Intake Piping and More

Harman Motive have just dropped their latest press release with their new parts lineup for the 2009 and later Nissan GT-R including full details, results and pricing. It’s refreshing to have all in one place so thanks to Harman Motive for the effort on their part.

First up, and picture above installed, is the Harman Motive Intercooler Piping Kit – aka the HM-GTR-ICPK – it’s a full kit of polished alloy piping to replace your standard garden variety, flexible rubber items. The piping increases pipe diameter by 3/4″ to 2 3/4″. The internal surface helps to smooth airflow and provide a more consistent high velocity air intake charge. They fit up to all the standard sensors and even your standard BOVs.

As you can see in the dyno chart above, the full intake system (HM-GTR-ICPK plus the HM-R35-CAI cold air intake) produced a decent gain in horsepower and torque from the mid range up. The Intercooler Piping Kit alone retails at the $1,395 mark but the kit together with the CAI in a package is $2044. All made in the USA.

Next up are the HM-GTR-DPK Catless Downpipes for Nissan GT-R. These lower exhaust restriction significantly by ditching the primary cats. Made from stainless steel they’re designed to be completely direct fit replacements. Also made in the USA they come in at $1,195 a set.

Thanks to Mike @ GT-RR.com for the heads up.

AMS Turbos and Downpipes Tested and Photographed

AMS Performance Nissan GT-R Downpipe

There’s already a variety of turbo downpipes on the market but move over and find room for one more. This one stands out of the crowd though since it’s the new AMS cast downpipes. We’ve been following AMS’s progress on these and are pleased to see how they finally turned out.

Featuring cast end sections with stainless centers AMS say these are good for a huge increase in power (20hp peak, 25hp mid-range) and response when combined with the AMS turbo upgrades. They should do great things for stock turbo’d GT-Rs as well.

Check out the dyno graph in the gallery below showing power and torque on the same graph. The red line is AMS turbos with stock downpipes while the blue line is with the AMS cast downpipes. Quite a startling result.
