custom vs bought exhaust
What is the difference between buying a pre-manufactured exhaust system, vs a custom made exhaust from a exhaust shop?
just trying to see why and what reasons ? I feel you can get a full system made for the price of the premade axle backs, and or similar prices but get what you want rather then what a company sells? Last edited by J_pasta; 04-20-2014 at 02:34 PM.. |

I guess it all depends on what you want. You could also build a car yourself as opposed to buying one "off the rack". ?
As for exhaust systems... I really LOVE my BMW Performance Exhaust. So many guys have put one one and never a negative comment. It's relatively quiet at part throttle but loud at WOT. Its the best of both worlds. No drone and it's a factory made part with ZERO fitment issues. Get one!

But for me, I wouldn't buy a premade exhaust unless it met MY requirements. Does it produce more power? How much does it cost? How does it sound? How does it look? If it can't do any of those properly, I would build a custom exhaust with the parts I selected. Wait...I'm already planning on doing that. |

The benefit of an off-the-shelf exhaust is that you can have some idea of how it'll sounds before making the purchase. To get a custom exhaust to sound exactly the way you want it, you'll need some experience, luck and / or a fabricator thats willing to work with you ($$).
Cheers, Bryan

Stainless steel pipe is not really that cheap. A fraction of the price of an exhaust, sure, but it's not exactly cheap. Mandrel bending machines are very pricey, especially ones that can do long lengths of 3" and larger. You could be looking at $100k easily. Good tig welding machine, and a skilled welder to do the work ... It adds up fast. Mufflers and resonators are not cheap either. A good Magnaflow muffler is around $100 or more. Plus tips, flanges. You could easily have $350+ in just raw materials in a downpipe-back exhaust for our cars.
You can get a mild steel, crush bent, mig welded, unfinished tip, cheap muffler exhaust for cheaper, sure.

And labour costs do depend on your location. Unfortunately, I live in a city where is seems no one will lift a finger for less than $100 / hr.

You're obviously one of those people who think 500-1000 for a muffler is somehow a "value." http://www.jegs.com/c/Exhaust-Header...10263/10002/-1 |

A custom exhaust can be fine tuned to increase gains in the RPM range. By reducing backpressure, and having a bigger diameter piping can help increase high RPM HP at the cost of low end torque.
Yada Yada.. |

certainly not looking to do this myself, and buy the tools. more of a take it to a shop type custom. And from what i have read, its more of a ease of purchase, and piece of mind for what you already know its going to do. |

I can tell you by experience that if you are going to do a proper stainless exhaust setup with all TIG welds, proper flanges and quality resonator and muffler you won't save enough money to cover your time to do it. I've built several exhaust systems for cars now and the parts aren't as cheap as you think unless you can get them locally. Shipping adds up quick.
Your only going to pick up 5-10 HP for an exhaust system on these cars, it's really all about shedding some weight and getting the sound you like. Seriously? Lets buy nice piping and take it to a bunch of shops that can't weld worth shit with a MIG that typically isn't even setup or maintained properly and they are not using stainless wire. If you going that cheap you mights as well just have them expand it and clamp it on.

personally i want to learn how to tig weld so i can DIY manifold/exhaust. either way, spending $1k on a muffler alone is pretty insane when you can get custom ones for a couple hundred bucks, let alone off the shelf ones welded on for less... just depends whether you're willing to trial and error for the sound you want! |

TIG welding isn't that bad but it's nice to watch somebody else in person first as youtube videos are pretty hard to follow. Welding stainless is pretty easy and you can go back and clean up your welds easier. Aluminum is the bitch and can be very unforgiving. Biggest thing is prep and making sure your cuts line up perfect, taking your time and having a proper system of clamps to hold everything properly is key.

for basically first time, it looked pretty close to perfect. and like you said.. spending several times longer prepping than welding is totally normal haha fortunately i hate the PE sound, so no worries for me :P |

I'm a DIY guy, and even though my time is in fact worth something it's hard to not be involved, so I tend to do the latter. I can't blame anyone for doing the former. |

OP: Two letters R and D. Take your chances with something you (or Midas) makes from whatever is laying around or they got from the nearby construction site, or go with a proven performer. The exhaust manufacturers aren't in business because of the number of suckers that are willing to pay such exorbitant prices for their products. :rollseyes:

Most of these companies that produce these products don't R&D: they make a guess, mock up some JIGs and mass produce a product. Raw material cost are cheap, labor equally as so - many products (after the design phase) are manufactured in Asia, and shipped over. This bottom feeder here believes that a name brand automatically offers a substantial boost in what you're able to manufacture yourself, or believes that 304 stainless steel at one shop is different than the 304 grade stainless of another. |

Midas is not going to make you a back-purged, TIG welded custom exhaust for $150 in labor. They'll slap something together with a MIG. It might work fine, I suppose. Nothing necessarily wrong with that. You can get an exhaust for a lot of cars off ebay for $250 or less. I don't think $500+ for a rear muffler alone is reasonable. This "you must be" routine is extremely childish.

So where are you going with this? You're obviously a brand snob who doesn't know what the hell he's talking about, and thinks that everyone one the internet is just as uninformed as he is. It's getting old - quick. |
