New Tanabe axle back for Nismo!!!

savoy49

...well sort of.

So two weeks ago I was helping a friend out and installing a Tanabe axle back exhaust on his 2011 G37S Coupe (Tanabe #T70132A). When we dropped the muffler it all looked WAY too familiar so I scooted over to the Nismo and had a look underneath and wouldn't ya know it all looked the same. We finished the install and went for the test ride in the G and I was in love with the sound.

Many searches later and i found a post on here with a G37 stock muffler on a base 370 and the tips stuck out about 2 inches too far. I started measuring and sure enough the tips on the G muffler were about 1 inch longer than the Nismo. I searched all over and couldn't find anyone who had tried this install. Knowing that the Nismo rear valance is longer than base I decided to give it a shot. I always wanted the Tanabe sound but I just don't like how their Z exhaust has the cross flow mufflers. Straight (angled) cans just seem like they would flow a whole lot better in my poor memory of fluid dynamics. Plus it is a Y-pipe design and i want to add the AAM Comp mid pipe when I'm done so I want a nice axle back muffler set.

I gave Ken @ Enjuku Racing a call (not affiliated...just giving a good shop a plug) and he beat the best price I found anywhere and got it sent right over. So i got to tearing down tonight while i waited for UPS.

... pics attached.



Needless to say I am very happy. Only "issue" is that you have to remove one little bracket on the drivers side that offsets the muffler hanger near the subframe. The G doesn't use this bracket and you bolt the rubber hanger to where you unbolt the bracket. (see pic #15)

The tips are about 1.5" longer but sit nice and flush with the back lower edge of the bumper. Tips are 115mm compared to Nismo 120mm. Piping ID is 58mm which is exactly the same as stock.

• Louder than the G by a little due to the more open H-Pipe design.

• Nice pops and gargles on rev match downshifts.

• Just a bit more aggressive tone than the G...not quite as tuned. Again this is probably the H-pipe vs Y-pipe.

Overall I give it a 9.5 out of 10. Would be 10 out of 10 if the tips were a touch shorter. I would not recommend this for base / sport / touring rear bumpers. Ground clearance is much better than most diagonal can mufflers i have seen.

Next step is AAM Comp Midpipe.

I hope you enjoyed.
