I like the look of the angle tips but can’t seem to find it anywhere, also I have read all about the fiberglass problem. If the problem were to come up, I would just replace the resonators with a magnaflow X-pipe (as a previous poster did.)

 

I don't think they are making the angled tip system any more. You might find a leftover one somewhere, but you would have to just start calling dealers. I installed the stright tip system and have not had any fiberglass problems in the 2 months it has been on.

 

You're **** out of luck

 

I figured as much! I just like the look of the angled tip, does the strait tip produce the same power??? I remember reading some where that it didnt.

 

Most likely the same extra HP, next to none!

 

i started a thread last night about my possible loss of low end torque with the dual Injen exhaust.....i have headers, crawford cats and the injen.....the car pulls hard at the upper rpm range, but seems to have lost some of its aggressiveness at the lower end.........anyone else feels this loss? you guys try the H or X pipe? i still need to run a dyno and check the a/f.....probably next weekend.

 

yeah it has been discontinued for a while, if your interested i may be able to get one...shoot me a pm

 

I know of the fiberglass problem, if I encounter this I plan to install a X-pipe in place of the resonators. I hear good and bad things about the gains from the injen, if tq is lost in THEORY the x-pipe should regain some. HP wise the injen has been said to put down alot, it is just weak on the tq.

 

I had an Injen for a while and there was a huge torque loss in the 1000 to 3500 range. I did the ECU reset following the TS page recommendations and I thought I got some back but it never seemed to pull as hard. I drive the same section of hill every day and with the Injen the car would bog down in 6th so I would have to down shift to really get going again. With the stock system I never had to do that. Then I took it off and put the stock back on and the car finally felt like it had power again, no shifting on that hill.

The design of the back boxes is totally different between the angle and straight tips. The angle tips have a removable restriction silencers (like the rice exhaust use), the straight tips have them shoved inside the back box (same rice exhaust silencer only now you can't take it out). When I wrote Injen about this the sales guy said that Injen R&D told him "cars need backpressure". Any exhaust company that says that has no idea what they are talking about. At that point I sold the system and got a Nismo. This made my wife happy because she hated how loud it was at low RPM. The Nismo also pulls my hill without a shift and sounds mean as heck when I get on it (otherwise it's just noticeable).

I have other issues with the Injen exhaust like the 2.5 flange to 2 pipe at each connection, the glass packing pumping out of the back boxes (due to exhaust gas getting pumped through the packing because of the restriction silencer), among others.

In theory if I throw an X-pipe on it where the resonaters are, it should bring the tq up. I just really like the look and sound of the injen exhaust, though if the x-pipes didnt work out it would suck to lose my tq.

Thank you very much for your input, I love to hear all the information people have!

 

I have the Injen straight tips and ran a baseline dyno with and without the exhaust. RWHP gains were around 6-8 and RWTQ was down around 3-4. So yes, the Injen does lose some TQ, but for me it was hardly noticable. I plan in the near future to add a H pipe to the exhaust and run some more dyno #'s.

I don't know if you have seen it but someone on 350 motoring installed a magnaflow X flow stainless resonator that fits exactly where the current resonators are now. This seems like a best of both worlds sort of thing.

Yes i saw it, there is where i got the idea from.

 

can either of you guys post a link to that thread? i am interested in the magnaflow mod as well.........thanks!
