Custom exhaust system. Any good?

Hey guys, 

So i've heard that going custom could be a better option than buying an invidia, or x force exhaust system. I want a loud and aggressive system, and i'm struggling to decide whether to get a custom exhaust made or buy a cat back system. I don't want to be paying a ridiculous price for just a basic muffler delete, which i personally aren't a fan of :7_sweat_smile:. Any suggestions?

So you have heard that getting a custom exhaust done is better than buying a brand name exhaust who have tested hundreds of different configurations and done hundreds of hours of R&D on their systems? Reeeeeeeeeeeealy?

There is a good reason people go brand name and cough up the big bucks. Lack of unbearable drone is one very, very good reason.

A custom exhaust is just as good as the person who designs and makes it. Most Japanese off the shelf exhausts have a restrictor that reduces a 3in system to 2 1/2 in so I avoid them. For best results post up your city at least and maybe somebody will recommend a good fabricator. You don't say what kind of car you have but a cat back exhaust means that you are still restricted by the current size of your front pipe.

You don't say why you want a new exhaust - the purpose will have a bearing on what you should get.

If you want to squeeze out as much horsepower as you possibly can, then it's an Akrapovic exhaust system you need.

If you just want a nice note without it sounding obnoxious, like I do, the one for my taste was the Megan Racing muffler.

If you want to be an obnoxious wanker, get a custom exhaust with tail pipes that you can house an illegal immigrant family in.

Then go do a tunnel run

Your welcome

How did you go about sourcing the HKS system? Can i speak to some aus companies and see if they can organise it all if the system is from america?

Ah I'm sorry I just seen that it's for the vq model whereas I was on about the rb engines lol. However I would say a decat is the key and decent exhaust and itll roar.. perhaps a butterfly in the decat that can be opened and closed so essentially you can make it straight through or tone it down for residential areas.

So jealous of you lot over in that side of the world heh! Would love to get my family and me out there!

What sort of horsepower gains did you guys get from exhaust upgrade for v36 skylines ?

I can't find the post but a user call Yo-Yo claimed big gains when he did his exhaust upgrade,

The post is years old

You will definitely get gains, but on an N/A car, it won't be crazy amounts. A tune would get you more even if you keep everything as stock. My V36 has a custom system. FI HFC to 2.5" mild steel to a magnaflow xpipe and 2.5" all the way to HKS Legamax mufflers. Sounds good, no drone, but I doubt it made more than 5hp lol.

Ok folks a question or 2 on the similarity between the exhaust on the 370Z and the v36? I thought I read some where that the 370z was 200mm shorter so is there any other differences?  I was looking at the Empire 370z cat delete pipes.

Not sure, but I assume they would fit considering Z1 motorsports make one-size-fits-all test pipes for the vq37.

Sorry I was talking about the whole system, as I believe the Z is shorter over all than the V36.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
