Hi, Was just after some advice from people who have tried various exhausts mods. I recently bought a new 200sxGT and was looking at all the Blitz and HKS exhaust systems and was thinking of going a 3.25inch from the turbo back with a hi-flo Cat and a straight thru Muffler. I was wondering if a custom mandrel bent would preform better than a mass manufactured component? I would like the exhaust to have a nice note and I have heard that the name brands are a bit quiet? Has anyone heard good things about the Blitz air pods? I've been told that they see a dyno'd improvement of 15kw at the wheels? Just by changing a pod? And 25kw at the wheels by changing the exhaust? Thats a lot of extra hp for bolt on's. Any advice or experiences? thanks. :? |

Dood you don't want to go 3.25" i would only go 3" that is a resonable size exhaust. If you start running REALLY high boost then you can look at goin bigger. Blitz air pods are good but expensive. As for the who the exhaust is mad by. These days Mandrel Bent is available everywhere and is a production type of exhaust. You can get a custom HKS or Blitz exhaust which produce a nice note and are quite load. |

I'm the second to criticise resin then... As Mcleod said, factory systems are often very restrictive. 5-10 extra KW wouldn't be a hard gain to find on a factory turbo... |

Thanks for the on going help guys, I actually watched the dyno on the airfilter and saw the difference, but at $445 it not a cheap air filter system! Worth it thou, and with a 3inch exhaust and hi-flo cat, I've had all sorts of quotes, ranging from $2000 for a Blitz system to $1600 for a custom job, but that's seems good Mattson, I'll go and see them. Unfortunalty I am unable to mod just yet, as my baby has developed a shudder at idle, and Nissan are scratching their heads over it, if I mod it you know what they will say! Even thou its an existing problem, I hope to have it fixed in the next week or so. So far they have replaced my computer and injectors. Also got a problem with the synchro hub in the gearbox, she won't go into 5th at high speeds 160+. They didn't believe me of course, untill we put it on a dyno and showed them. Guess my baby's got a few teething problems! I do have the end picture in mind and I can save like buggery in the mean time! |

HAHAHAHA yeah I kinda got that look, like WTF! But hell its a PERFORMANCE car! It will go from 4th at 180 across into 6th , but 5th is having a tea break and just being damn ignorant. At least it was tempremental and ficked up when it was at the Doc's. But they have to report it to Nissan Japan and document all repairs as it is an uncommon fault. Meanwhile I wait.............and wait.........you'd think for $50000 you would get some customer service. HEHEHE 2000km on the clock. |

The thing with the mass produced ones is theyre made specifically for each car, and are designed especially for each make/model. A lot of testing goes into these systems, and thus you get the high price tag. either way going 3" should make a decent difference. Also from what im told, nissan wont care too much if u get another exhaust on it. i think they will only void the warranty on your stock exhaust |

I couldn't agree more garyd, I think you seem to pay for Research and Development, and the fact that these companies rely on these bolt ons to be the best they can be or ........no sales. The thing that scares me off going to 'insert joes exhaust's name here' is the fact that you might save a few hundred dollara BUT, unless you witness the entire A to B job, what corners are cut while you arent there.....to me I've decided Piece of mind is worth a few extra $$$. Agree? |

Hmmmm I think I might go for a name brand, I have looked at the websites etc, and I think for the price I might stick with a Blitz system....BUt LOL i have been known to change my mind........hehehehe |

At least there are tried and true systems in Australia for your rice cooker, like bigger rice bowl, and extra steaming attachments, but spare a moment for us poor chaps who own the best of british assembled, german designed, brazillian engined supercharged pickup cars. Where do we get a garunteed result of increases at the wheels? I mean I'll trade 1 kw if I can get away with just a new exhaust instead of some stainless steel waste of money. But I guess I'm not turbo so it's not as important for me. |

im currently saving my $$ for a blitz system and a few other mods, pod etc. i think i'll stick with name brand, mainly due to the R&D performed. :shock: |

I always prefer to have custom fabrications & try to steer clear of the name brand stuff (for exhausts & filters anyway) because I don't believe that the extra 1-2 hp gained is worth the cost....usually at least $1000 difference between a custom fabricated exhaust from the turbo & a name brand system...i mean, thats more than the cost of a digital boost controller, & you would gain alot more usable power/driveability from installing one of those...Having said that, name brand (Blitz etc) do look the part!!!!! |

*shrug* I'd rather a shitter that hammers than a show car thats slow :? Having said that, I'd actually rather a compromise of the two - something that goes hard but doesnt look totally crap. Which is where Brutis2 comes in

If you buy a pre-made zorst, then I suppose your buying a design that's been proven and tested on that car. So, if you want to spend the bucks on that, and it's alot more money that just having one built, then go for it. Remember that maybe the Blitz zorst for a S15 was maybe used with a different turbo than the one you got? Maybe they have different pollution regs in Japan? Dont' forget the different RON in the petrol. |

Yeah i have heard that Robert Bliss does a damn good job. My father got a zorst and bleed valve fitted at John French Subaru and they did an awesome job. (mind u he has a rex not an s15) They also service a few other makes and models 2. |

I think the thing that held me back from going custom was exactly as disco lou said, the 'unknown flow etc'. and for the price wise i got a full turbo back blitz exhaust system, plus hiflo cat all fitted for under $2000. The best custom job quote i got with a hiflo cat was 1580. So the extra $400, i consider that a worthwhile investment. Plus it just looks mmmmmmmmmmmmmmmm |

Wow, that custom quote is expensive! Trouble is, when u go to an exhaust shop with a nice car looking for a custom job, they see the car & go 'he can afford it' & then proceed to rip you off (I've had this attempted on me so many times it aint funny!). That said, you should probably be looking at no more than $900-$950 for a full S15 system including hi-flo cat & dump pipe off the turbo.. With a stock turbo etc the difference in hp would be next to nothing, even with a bigger turbo if the custom job was good it would probably only be(at most) 5hp down on a 'name brand' system (it may even be better, depending). Which leads me to......how many other mods could u afford with the extra $1000? Boost Controller etc, etc..... |

Yeah dodgi, I considerd the $400 a wearable cost for Research and Development, and for the juicy looks.............but $1000 , mate i had 6 quotes and never got close to that. I agree completyly with the nice car he can afford it quotes, but all were around the $1650 mark for custom. Otherwise if it was such an extreme then yeah it is literally the cost of a boost controller and some rice bits. ahhh well bring on the blitz i say! i dont see hpw the apexi can be $1000 more than blitz, now THATS unreasonable. |

I've got a mild steel 3" m/b system fitted at Aussie Exhaust at Albion. Cost me $850 fitted with everything except a dump pipe. High flow cat, hot dog resonator and straight through muffler. Sounds pretty sweet and a little cheaper than the system I had on the previous car which I didn't like as much. |
