Couldn't you just put them further down, past the collectors, or anywhere else where they would still do their job but not interfere with other functional elements? Maybe I don't know enough about it...

I didn't realize the elimination of cats is what gave them their name. That makes sense though.

That's why I asked the question. I thought setting it up the way I suggested would be more efficient and sound better than the shorty/hfc combo while still remaining legal.

No because the distance from where the LTH meet the block to where they meet the exhaust is a certain distance. That distance is the same as stock headers + cats/HFC combo. Most if not all of the exhausts are made to fit up to the stock mounting point. If you add onto the LTH by adding HFC then you would need a custom exhaust with adjusted measurements to mate up to it.

Not sure if I explained that well enough but I gave it a shot.

Close enough I at least get your point. Just change where the header meets the block to, where the header meets the head of the engine...

You could. I was just assuming you'd want to retain the ability to bolt on to any CBE.

On a side note, my Stillen headers and Berk HFCs will be for sale soon.

Daishi · 03-25-2010, 10:44 AM

great gains but im wondering whats going on with the top of the graph it seems like there is a bottleneck somewhere.. maybe the stillens suck? it cant be the LTH's or FI catback.. thats the most free flowing setup on the market.. only other thing it could be is the stillen intake, they probably just slapped together an intake in 2 seconds and put it on the car without any testing.. wouldnt surprise me.

Wow, that is hands down one of the most asinine things I've read on this forum in a long time. And that's saying a lot, considering some of the posts I see every day. You have some kind of past bad experience or grudge with Stillen or something? I mean, saying that some product has some deficiencies is one thing. But it's a bit of a stretch to go from that to saying they just slapped it together in 2 seconds and did no testing, don't ya think?

If youve read the posts on this forum and the g37 forums most are complaints of a horribly designed product that doesnt fit right. Most of their products have horrible fitment and youll see many posts about it if you looked around which leads one to believe they slap parts together. Even tony said that the g3's offered no power over the stock intakes once you have an exhaust on the car and made the car run horrible. Dangerous level of A/F. Im sorry semtex but the only reason you are being so defensive over this is because you spent some of your hard earned money on their inferior products. I have no grudge against you as a person I just hear way too many complaints about stillen. Have you heard any fitment, power, or customer service complaints about Fi? no.. Stillen on the other hand you hear it ALLL the time.

I'm not trying to be defensive, I'm trying to be fair, which I don't think you're being at all. I will be the first to admit that Stillen products are less than perfect and while some of them are great, some have pretty serious issues. The only point I'm trying to make here is that there's a middle ground. Products don't have to be either perfect or complete and utter crap. It doesn't have to be one extreme or another. Are the G3's perfect? Nope. But that doesn't mean we have to automatically go to the opposite extreme and accuse Stillen of doing absolutely no product testing at all, do we? I mean, that's a pretty harsh accusation you're making there. Zero testing? Maybe they didn't test enough. Or maybe their test methodology was flawed. But zero testing? No testing whatsoever? C'mon man, that's just unfair. We don't have to go to such an extreme to offer legitimate criticism of a company and/or product. Let me put it this way. I'm not a big fan of our current President. I think he and his policies have many faults. They are far from perfect. But that imperfection doesn't prompt me to go to the extreme of saying that he is utterly and completely without merit either. That would be disingenuous, IMHO.

I agree maybe i shouldn't of said they did zero testing but think of it this way. No matter how you slice it whether they didnt do enough testing or their methodology was flawed it still leaves their product in my eyes in the end still as flawed as if they did little to no testing at all. I mean does it take a genius to make a couple systems, install it on a couple different cars and say holy crap this system doesn't fit right, lets fix it. No they ship the product anyway.. But lets just say for arguments sake they didnt experience that problem and all was well.. You would think after all the fitment complaints they would actually fix the problem but no to this day people continue to have problems with their products with no fix from stillen. Instead their answer is hey we are designing a new version just buy it when it comes out.. uhhh no fix the product that you sold me in the first place or give me the new version when that comes out free of charge.

I dont want to turn this thread into who has a stillen product that fits right and what not but look around.. google it too hey theres even a website dedicated to stillen.. www.stillensucks.com lol way too many people have problems with their products and customer service. seems like stillen is hit or miss.. anyway back to the topic.. If anyone would like to further discuss this feel free to shoot me a pm. I mean no disrespect to stillen owners Im just merely stating what I read all over the place.

semtex · 03-25-2010, 11:11 AM

Btw, for the record, if Tony makes intakes, I'll most likely sign up for those as well. But I feel no need to bash another company in the process. Quite frankly, with the hit that the aftermarket has taken in this economy, I'm grateful to any company willing to step up and develop parts for us and give us options.

Maybe your ok with people spending their hard earned money on a product that has a good chance of causing them problems but im not..Thats not to say that Im going to go out of my way to post in every thread saying stillen products suck but I did feel the need to voice my opinion in this thread because the evidence is irrefutable. If someone asks my opinion on the stillen product I have no problem telling them hey dont buy this product because of such and such.

No, I'm with you on warning others about problems. Maybe I haven't been sufficiently clear. I have absolutely no problem with legitimate criticism of a company and/or its products if they're not up to par. My objection was based solely on the 'zero testing' remark. In other words, if something sucks, I think we should all say so and warn others, tell them what the deficiencies are, etc. I just don't think it's necessary or helpful to exaggerate those deficiencies is all. (The zero testing claim, for example, would be what I consider to be an exaggeration.)
