Follow up to the failed emissions and safety test earlier this week.  Last night I got under the car again and checked for leaks, found that one of the gaskets I hadn't touched was leaking, so I tried to cover that up with some exhaust tape.

Project350z Garage WorkSo what did you do this weekend? Did you spend two days under your car? I basically did, well more like 1 day, but it was broken up over an afternoon/evening and then the following morning after I ran to get a new “nut” that I needed to finish things up.

Why was I under the 350z? Well, removing the fun parts of course. I planned to remove the front and rear Hotchkis sway bars, along with the TrueChoice Phase 4 Konis (front) and the off the shelf Koni Sports (rear) along with springs/perches. Though in order to deal with the rear sway bar I also ended up pulling the Injen Super SES exhaust system off the car as well and put the OEM exhaust back on.

If you followed the blog post earlier this week you already know that Injen came through and got me the replacement midpipes for my Super SES Exhaust which I removed late last year.

Today I took the OEM exhaust off the 350z and put the Injen exhaust back on. The job itself is easy, probably could do it all in about 25 minutes if I really pushed it, but I didn’t. I took my time, cleaned up in the garage a bit, cleaned up the exhaust a bit as well. I also managed to weigh both the Injen exhaust and the OEM exhaust to see what the difference was. I was hoping it would be more!

So I’ve been trying for 4+ months now to get some customer service from Injen Systems for the Super SES Exhaust on my Nissan 350z that has a massive leak in it.

Back in August I received a response from Injen

Hi Chris,

Can you send me a picture of your exhaust? I guess we had a few different ones made for that same vehicle and a photo would make it much easier to figure out what part and get you the correct part.

Thank You,


I responded with photos of the exhaust and what I needed. I have heard nothing back. I’ve emailed them multiple times, even emailing their tech and info email addresses, but so far I have not received a single response from them since that email quoted above.

I sure wish I could get some help, I actually liked the exhaust on my 350z, but this has to be the worst customer service ever!


UPDATE: I'm glad to say that Injen came through and got me the replacement parts I needed!

If you’ve followed my struggles here on you know by now that my 2004 350z came (when I purchased it in January 2010) with an Injen Super SES exhaust system. This system was a true dual exhaust setup from the cats back. Read the full blog post for more details, and the YouTube timelapse

So I still have an exhaust leak in the Injen Super SES System on my 2004 Nissan 350z. And I must say, I’m not too happy about it. I blogged about this over a month ago, almost two months now. I actually emailed Injen at the time, and I got a fairly quick response inquiring about photos of the system so they could try to figure out what replacement parts I need.

Since then there has been radio silence. I emailed them the photos, I’ve emailed them since, and have heard nothing back. At this point in time I’m going to have to suggest, if you’re serious about your ride, stay away from Injen Systems. For cold air intakes, exhaust systems, whatever they sell. If this is the customer service they provide I can’t suggest that anyone ever buys a product from them.

So I spent the afternoon yesterday trying to repair a leak in the Injen Super SES Exhaust system that was on the 350z when I purchased the car back in January. Sometime in March the exhaust started leaking and it has slowly gotten worse. Normally I would of just scrapped it and put something else on, but with all the life changes (new job, moved to California, trying to sell the house in Colorado, prepping for our first child) we’ve been going through the budget hasn’t allowed for that at this point.

So it’s been a while since I’ve done any updates here on, so here’s a quick update. The car has been doing well the past few months but at this point has been relegated to strictly commuter duty, and it will likely be that way for a while now. Though I do hope to hit an event or two here in the coming months, hopefully on towards the end of June and another 2 or 3 in July.
