Got Stillen G3 Longtube intake & Exhaust.. What next?
 

I've got the Stillen Gen. 3 Longtube intake system with the Stillen exhaust system and i need some adive on what to get next.... Thinking about the stillen headers and not sure about what test pipe or hfc to put on... Any suggestions? Thanks guys

I say get headers/test pipes when tuning is regularly available.

However, if you are worried about backpressure and low-end torque, stick with HFC's. Berk would be a good choice.

Another way to gain a little performance if you don't want to mod the exhaust [yet] is to get rid of some spinning mass. I recommend light weight U/D pulley and/or lighter wheels and tires if you haven't done that. Dropping weight on the wheel/tire combo makes a pretty noticeable difference.

Sorry to Hijack, but I was going to ask the same question. I have the G3 intakes and Stillen Exhaust installed. Also getting the Stillen pulley and grounding kit done tomorrow.

cant get the HFCs or headers because they arent CARB legal in CA (damn you CA!), so I was wondering what else I could do to my Z?

You could do some minor upgrading of the brakes if you're so inclined. Like braided lines, for instance. Those things make a huge difference in brake pedal feel. Firms 'em right up! Switch the brake fluid over to Motul RBF600 while you're at it.

Thanks ill look into that! I guess the lack of upgrades means I can save some money for now until better stuff comes out!

Berk HFCs really open up the exhaust.

I want to, but I live in CA, and HFCs arent CARB legal, so when it came time for smog testing, id be screwed.

Don't you have like 5 years before you need to get a smog test on a brand new car in CA or something like that?

5 years is a long time to wait to be screwed.....:tup:

:iagree:

Keep the stock stuff somewhere, and in 5 years just swap the old back in, smog test, swap back out! :D

I wish Virginia allowed 5 years....we only get 2 years between emissions. :icon14:

But what's the test procedure in VA? I doubt it's anywhere near as stringent as it is in CA.

An O2 test is an O2 test - it'd still require swapping out the headers/cats again :)

Yeah but not all jurisdictions do an O2 test. In GA, they just hook up a cable to the OBDII sensor and check to see if you've had any recent CELs. If you haven't, you pass. It's that simple. No visual check, no sniffer. The only time they do an O2 test is on older cars that don't have an OBDII port. My 350 passed emissions without a problem and I was running test pipes.

Arrrghhh....I already paid for all the upgrades I want and this emissions pass/fail makes we wonder should I really go thru with it. I wish I understood more about cars than just starting them and filling them up with gas.

After all my research on here and other boards these mods are a no brainer. The intake will be first for me since I can do that myself.

I have a question for those who have this. I saw some people mention that there is an exhaust rattle with the Stillen cat back. Is that true for all, or does it depend on how it's installed? Is there something I could tell them to watch out for when they are installing it? Thanks.

It's an installation issue. The instructions say to jack up the middle section before tightening all the bolts. Tell them to really, really jack it up as much as they can before tightening everything, otherwise when they remove the jack, that mid-section may hit the crossmember.

OP, would be helpful to understand what your objectives are for the car so we can give you more targeted input on mods that you might enjoy... street only or track? if track, what level are you at / hope to be at? 1/4 mile, auto-cross, time trial, and/or wheel to wheel racing? if street only, what kind of driving? do you want to impress your lady, your buddies or just go fast? etc

Also, check out some of the member galleries for ideas on mods that have been done and impressions

Thanks for the info Semtex! I'm glad to hear that the rattle can be avoided. That exhaust sounds so sexy.:yum:

BTW is that your Z on youtube posted with the name "chanbenb"? Just curious.

Yes.

niterydr, I can confirm that the Stillen CBE you purchase from Stillen now easily clears the rear crossmember. Go for it!

+1 Stillen has fixed this issue and they fit perfectly.
