Hey does anyone have the fiberglass blow by problem with this exhaust. Evertime i wash my Z after driving it i have shiny metallic shavings on my rearend.I know the G35's had this issue, but does anyone else have this problem with the Z. I contacted Injen and they seem to act as if no one ever wrote to them.

 

I wrote to them last week and still waiting for the reply. my driver side seems much louder than the passenger side. I had that problem before

 

I seem to have this issue as well. One side seems louder than the other. If Injen doesnt contact me soon im going to go to the better business bureau on them. For not backing up a issue they sure the h### know about. It really sucks that a company like themselves is that **** poor to not even reply to our emails. I guess they dont realize if no one bought their products they would be out of business. Im just really getting annoyed having to wash the rear end every time i drive the car. To top it off i have about 10,000 miles on it. How long does it take to break in INJEN? Give me a break it sounds like a bunch of sh#t if you ask me.

 

Yes. Small dark particles on the rear of Pikes Peak White. Easily removed with wax.

 

Well Injen finally got back to me,and seem to be willing to help. So i guess i am getting somewhere.

 

If it's the hairy glass on the @ss, wash it off, any rubbing can cause fine scratches in the paint.

4myz350's Injen still glasses his @ss.

Mine did this, wrote about it on my website here http://www.hypersprite.com/auto/pict...d002/injen.asp you can read Injen's response and my rebuttal at the bottom. When they said "Not all engines need free flowing exhaust pressure" I realized they had no idea what they were doing.

Some will say it is the front boxes but using a camera, they look like pretty normal perf tube glass packs, no real reason for them to be pumping glass. If you pull the back box off and flip it end to end, you will probably hear the packing fall from one side to the other, Flip... Thunk- Flip... Thunk, like there is about two inches of air inside for it to move in.
The earlier angled tips were a far better design but in either case you have to buy into the 50mm tubing as a good idea.
