Chinese Longtubes vs Reputable Mid’s
hello, I’m wondering what your folks opinion is on buying some XSP Longtubes as opposed to mids from a reputable company like eurocharged or kleemann. I do recall a thread posted by a member here a while back that showed true performance gain by switching from eurocharged mids to maximizer longtubes. is all the extra labour cost associated with the poor fitment of the longtubes worth it in the end? Or am I better off getting mids and not having to worry about quality? Would love to hear some input from people who use these XSP/Maximizer headers on their vehicles as they are on sale at the VRP website so I would like to pick them up if they are worth it and not a big hassle installment wise thanks |
Have a look at the YouTube video Alex did on these (legitstreetcars). It doesn't look worth it to me personally but it's not a right/wrong decision. Some people have no issues, others have on going problems. I would pay the $3k for quality long tubes or use the cheap mid lengths depending on my budget as they have far fewer fitment issues than longtubes. Depends what you are willing to deal with.

thanks for the info, i’ve read that the Kleemann/eurocharged mids are also prone to cracking. little bit torn...i really dont want to drop 3k for ARH/MBH headers but it seems like every other header has some sort of issue |
They should all be reasonably resistant to cracking with good engine mounts. Grab the black series mounts or poly if you can deal with the vibration.

I made that thread. Hands down it was worth it. Gained over a car length in a roll race and saw 1.8 mph more at the drag strip at high DA. Dropped close to 1psi of boost when i switched to these long tubes from the mids as well. I have the Maximizers on my E55 and fitment was pretty good. I had an exhaust shop add V-Bands. The clamps that come with it aren't the best. I helped my friend install his XS Power headers and that was a pain. Had to take it to an exhaust shop to adjust the mid pipe to get it to fit and add v-bands.
Maximizer> XS Power is my vote. https://www.ebay.com/itm/Maximizer-H....c100005.m1851 Very impressive! any issues so far with the maximizers? I was told by VRP guy that the XSP and maximizer headers are a carbon copy of each other and that there really are no differences |

I don’t know how true that is but I’ve seen and installed both. The Maximizers come sand blasted, a lifetime warranty, a decent merge spoke and the mid section fits great. The XS Power we’re a living hell. The collectors had leaks and the mid section is not bolt on. We made it work with the help of an exhaust shop rewelding the collectors and modifing the midsection to get it to fit. |
Both junk,but the l.t eBay are better overall |

Maximizer and XSP are virtually identical, XSP have flex pipes.
Alex just made a great video where he swapped from mids to Longtubes, watch to the end for the final result (TLDR: They fit with minimal modification, no rubbing, noticeable difference in power) XSP are on sale right now https://vrpspeed.com/index.php?route...product_id=393 We will be removing maximizer and OBX from our site in the near future as these have replaced them entirely. we have sold over 60 sets of the XSP, and generally all feedback has been good. |
You get what you pay for. A pair of merge collectors from Burns Stainless will cost more than all these complete 'headers' mentioned in this thread. If you want to squeeze every single BHP out of your engine you go with equal length headers. If you just want more noise, you'll be fine with whatever your budget allows.

Is the money difference worth the difference in power between equal length and LT? Lot of variables. |

I doubt it. The performance is likely to be very similar between long tubes and specifically designed equal length. Of course properly designed headers are probably engineered to a quality where you get zero fitment issues and no reliability problems, maybe this brings the value for money in some cases.

LT headers will make more power than the stock OEM exhaust. 40-50 whp is nothing to sneer at. It's not just noise, it's power. Are equal length headers better, usually yes. (Non Turbo)

No. Equal length headers make zero quantifiable difference in power on a blown V8. They can change the note, however.

which headers are those? I'd be more worried of the metallurgy used in Chinese headers versus American made. I am assuming the MBH and ARH header material is USA manufactured. Chinese metals are shi#. |
I will be going the headers route as well, I get worried about quality since I had a really bad experience once. I had a 01 M3 and put headers on that and the leak and a big one at that was in between were all the pipes come and connect to. No matter what we did couldn't plug it up. Didn't want to pull it off and maybe fix it and put it back on. Even so on that car it was big gains I felt an immediate difference so I can only imagine on our engine 40+rwhp is a lot.

Prove it.
1. You said equal length headers don’t exist. I have them in my car. 2. I gained over 50whp by replacing Kleemann headers with them. Pics and graphs in my Instagram somewhere. |

Alex,

BTW: I lived in Farnbourough (North East Hampshire) many years back. PS: Hampshire is nice. I’m an hour north of London in Bedfordshire. It has the least amount of annual precipitation in the UK which is great. |
