Depending how many mods you plan on doing, you have to decide what size piping and what material to use. Most go for 2.5" piping with mild steel, which does reduce rasp somewhat compared to stainless but will have a shorter life span compared to stainless. There are gains to be had with 2.25" exhausts but it's not too much bigger than stock, the main advantage would be the additional flow without restrictions added. I run 2.5" mild press bent, which does cause some restriction but I haven't reached the limits of needing mandrel bent as of yet.

Generally moving to high flow cat can get some occasional pops, I have previously ran stock ported headers now on custom 4-1s headers and they still pop every no and than. So look into getting a high flow cat if you have the funds. I have seen some with stock cats also pop occasionally as they do flow reasonably well for a standard item. 

You will also need to consider the muffler as this completes the sound and will help greatly with flow.

Generally the pops are just un-burnt fuel that gets ignited in the exhaust system. I recall even my completely stock exhaust system did it from time to time.

squalled, i swear to god, you've come to the rescue on every single topic i've posted so far 😂thanks so much, bro 

EDIT: i have NEVER managed to get the stock exhaust to pop whatsoever lmao. its super quiet for me hahaha

Hey guys

just wanted to ask something real quick

i want to get a new exhaust system for my 04 sportivo. looking for something that doesnt sound raspy or like your typical fart can. also, i would REALLY love to get any pops and bangs out of the car but i don't know where to start, but i'm assuming that an exhaust is a good way to get those crackling noises when you decelerate or rev the car hahaha. so any tips on that would be amazing too 🙂 

so if yous can maybe give me any options for a good sounding exhaust and ways to make the car crackle/pop, that would be highly appreciated!

thanks heaps!

"The pipe was 3 inches in diameter". That's the issue. Although you can run a 3" intake on the 2ZZ, to run on the stock ECU and/or piggy back systems it needs to have a reducer at the MAF of 2.75" otherwise you get issues to what you were experiencing.

I run a 3" intake but it has a 2.75" reducer at the MAF so there are no issues. To run a full 3", as Ben said you need to get an aftermarket ECU.

Thank you soooo much, dude! I'll see if I can put the setup back on soon, and I'll let you know how it goes 🙂

Thanks a ton!

UPDATE: I have since reverted back to the stock setup.

There were no leaks I could find, and I cleaned the MAF with special MAF sensor cleaner. It still did idle quite rough. The pipe was 3 inches in diameter and the MAF sensor was oriented correctly. The revs would climb and drop and repeat that cycle over and over again. 

It was also the Original MAF sensor 

Here are photos of the parts I used:

Note - the 2.75in to 3in hose didn't fit on the throttle body so I had to use a regular 3in PVC Hose 

I also used hose clamps even though there are no pics of them below hahaha

Hey guys so today I did an install for a custom intake system. Was around 140 bucks. all it is, is some pipes and rubber hoses and a pod filter and I expected it to work. However, this happened:

The engine idles so poorly and sputters and recovers itself from almost stalling for no reason 

When I start the car, I'd have my foot PLANTED to the floor and absolutely nothing will happen. It just accelerates like a snail and then after a while it drives normal-ish

Low end power is super **** but when lift kicks in it kicks in hard. I guess thats what the pod is meant to do but I don't think it's meant to do any of the earlier things I've mentioned. 

SIDENOTE: I've had to tighten the throttle cable just the slightest amount so that it can give itself gas and not die when it idles. Has anyone had any similar issues? Or have I totally ****** up in some stupid way? 

Thanks

Hey mate, welcome to the forums.

Mine actually does something quite similar what you've mentioned. I've had a gearbox rebuild earlier last year and it has still remained after the rebuild. My gearbox was completely inspected at the time and everything else appeared in working order. I've never had gearbox issues other than destroyed synchro's but I believe it may be the diff making the noise.

I've been in a few other Sportivo's and have noticed the same sound. I believe it's more than likely a normal diff sound. You mainly have worry if you hear a solid clunk and feel it too meaning the diff is likely damaged and needs replacing.

As for the engine mounts, you'd likely feel a large amount of engine movement if they were damaged, it's worth a look to check they are done up tight though. The stock mounts in my opinion are rubbish and after about 20000 kms they will start showing excessive movement.

Hope this helps.

Thank you soooo much dude. I still haven't taken it to any specialist. I'll take your advice. Thanks heaps bro :)

Hey guys! I'm brand new to this forum. not sure if this forum is totally dead, but, I guess i'll ask the question anyway hahaha

So, i've owned this Sportivo for almost 2 months now, and ever since I have owned it, i've noticed the weirdest noise coming from the car. i have no idea what it could be, but i suspect it could be the transmission.

The noise only happens when i'm coasting with the clutch out. It gets louder the faster you're going, or the higher the RPM.

Example scenario:

Say, I'm accelerating at about 60kph down a road and I'm in 4th Gear. as soon as i let off the accelerator, and i don't have any pedals pushed in, this weird, metal on metal grinding/whirring/friction-y noise comes from somewhere in the car. I don't think its the brakes, because, whenever i push the pedal in, the noise is still there and hasn't changed in any way at all. So, my biggest suspicion is the transmission, specifically, the clutch or the Throwout bearing. I want to take my car to a specialist to have it checked out, but i don't want to go to some stealership without knowing whats wrong with my car first. 

Has anyone else had this weird grinding/rubbing noise come out of their Sportivo? If it helps, mine is totally stock. nothing has been changed on the car in my ownership, or its entire history.

Any help or feedback would be really appreciated :)
