> [@Ceramic vs Chrome Header](https://forums.speedlife.net/t/ceramic-vs-chrome-header/13635/6): > > Tricia…I really hope you don’t honestly believe that all headers are “just hollowed out pieces of metal”…and that “metal is metal all day long”. Everything from the diameter of the primaries…to if the primaries are stepped…to the legnth of the primaries…to the path of the primaries…to the collector…to the legnth of the collector…to the type of collector…to the the material the header is made out of… etc. and how well those materials are all put together, allllll determine how much power you can make out of it and where exactly in the RPM range you will make that power. You may not “see the difference”…but the difference between $150 ebay headers that may look good to your eyes…and real hand crafted headers like Bisi/SMSP/RMF/HiTech etc. is astronomical. Like I said before…ebay headers are for the “everybody” that’s just looking for generic aftermarket parts to add to their mod list. Headers like Bisi/SMSP/RMF etc. are ordered and made to exact specifactions for owner specific motor builds. You don’t just click “Buy now”…or “Add to cart”…you call guys like Bisi or Randy…you talk to the man that’s building your header with his own hands…you go through your entire motor set up and find out what best fits your application. Maybe it’s just me…because then I think “header”, I NEVER even consider companies like OBX/MEGAN/SSautochrome/ebay whatever…even exist. Because they are just far inferior products in design, materials and performance. I’m not saying that NOONE should ever get one of those products…because I have no problem with people on a budget that’s just looking for a few extra ponies getting this stuff if that’s all they can afford. But to anyone that’s looking to make the most power…they’re looking in the wrong place. I agree with Jeremiah. I had SSAutoChromes on my Maxima (headers and y-pipe). What a waste. I make more power with stock headers. lol. Not to mention fitment wasn’t exact and I actually had to heat up and bend the front section of the y-pipe (down pipe) in order to squeeze it past the oil pan. My motto (now) is go big or go home. I decided to just stick to stock power wise since I’m more into look of the my car than the performance of it anyway. That’s why I have real light weight wheels from a good reputable maker (5Zigen), a good suspension setup (not some ebay stuff that’s been cut to be shorter - I have Tokico Illumina struts and H&R springs), and when I get my second set of projector headlights…it will be the beautiful Acura TL projector with the ZKW lense (best cutoff on the planet). It costs money, but in the end…not only did you do it right, but you set yourself apart from all the people who have mods that they paid pennies for and don’t match yours in quality, finish, etc. A 190hp V6 with a 15 second 1/4 mile is good enough for me. I like the twisties out here in the boonies anyway. I don’t need a 13 second or less car. Save your money and get quality. You’ll be happy you did later. --- _[View the full topic](https://forums.speedlife.net/t/my-07-si/241544)._
