2003 Infiniti G35 advice wanted

Exhaust, suspension, and/or AT advice and recommendations.

Yep, don’t do any modifications. Use OEM parts or parts that “ meet or exceed” OEM specifications. Transmission fluid drain and fill at 30000 miles using manufacturers specified transmission fluid. But this car is 16 YO, do you know it’s maintenance history?

Thanks for the reply -

Yes, I’m the second owner - Bought it in 2008, 65k miles. Today - 130k miles.

My Y-pipe just gave up the ghost - I wonder what the dealer gets for one of those.

Yes, I’ve been “swapping” 3.8 qrts of Nissan/Infiniti Type J (now S?) Fully synthetic ATF most summers. Helps the shifting, but there are some clunks and bumps now and then while underway in D. Also downshifts readily - will be less of an issue when I have the stock muffler (but not mid) reinstalled.

I wasted a $400 on a Megan Exhaust - too loud. The advice about buying the Nissan midpipe from a 6MT model - trades top end for the midrange - and cuts 50 pounds or so.

Cheers,

Jim

If I remember correctly this is an expensive car to mod. I doubt that has changed much.
