New Maptun Exhaust on My Saab 900 Turbo!

[@m.akbart3840]

I can't get enough of the sound of the B202. It reminds me of a Boxer motor.

[@AutoAutopsy]

Someone said that on IG yesterday and I can’t get it out of my head now 😂 it definitely has certain rev ranges where it gives off that sort of sound

[@asamyers4572]

As James may once said, “RTFM. Read the f*cking manual.” It sounds nice. I like the warbles of old 4 cylinders. I wish there was a way to make a 9-3 sound like that.

[@AutoAutopsy]

It’s a bit of a bummer because it’s so hard to make modern four cylinders sound good. I am pretty happy with the Maptun system on my 9-3 though

[@jamescgarrett6356]

Thanks for yet another fab video! One comment at 11:20 made be chuckle - “I tried to repair it with a hammer.” My type of engineering exactly :-) Keep up the good work and keep well

[@AutoAutopsy]

😂😂😂 thanks!

[@ArktinenPeikko]

Man, i really miss all of my 900's.... That exhaust sound is such a unique and nostalgic thing... I mean, the 2,8 V6 has a nice tone too, but all the saab's own 4-cylinder engines just have that very distinct note. Never heard it anywhere else.

[@AutoAutopsy]

100%! Very unique. The 2.8 V6 sounds good too

[@vincentlagrua]

For the tip fitment, you could cut the pipe after the muffler to allow the tailpipe to seat further in which should allow for you to get the look you want.

[@AutoAutopsy]

Yeah! 🙌🏼

[@tompettersson3814]

The hook wont line up then.

[@AutoAutopsy]

Update - I misread your comment. Unfortunately I couldn’t do that because then the rear hanger wouldn’t line up :(

[@TheoPhilpot]

Much more refined sound. Lovely!

[@AutoAutopsy]

Thanks!

[@bdlii]

To me they both sound about the same on video and both sound pretty darn good. Still nice to have a new exhaust without the giant hole in the bottom. I agree the tips need to be cut. I know this is a DIY channel but maybe a muffler shop could do the cut for you. Very cool car, a keeper.

[@AutoAutopsy]

Thanks! Watching the before/after, they definitely do sound similar (which isn’t a bad thing since I liked the sound before). The new exhaust is a bit quieter while cruising which I’m really happy about

[@letsgobrandon1300]

Love the upgrade. Sounds good. Always nice to have freshn parts on too

[@AutoAutopsy]

Thanks, it definitely makes a difference!

[@Crazy-Caveman-qh2dz]

the new exhaust sounds pretty awesome

[@AutoAutopsy]

Thanks!!

[@tompettersson3814]

I visit the exhaustfactory every once in a while and they manufacture them in smaller batches depending on how much they sell. They used to make bigger batches so that alot of company could have alot of them on the shelves. The end pipe is designed to fit the flatnose bumpers.

[@AutoAutopsy]

Thanks for that explanation!

[@nicktozie6685]

This quite a delicious auto, lucky man. SWEET

[@AutoAutopsy]

Thanks man, I love it!

[@TheNismo777]

This video got instant like when I saw milwaukee tools. You're right it does sound amazing eith that exhaust

[@AutoAutopsy]

Haha, they’re good tools! I love em

[@Blutnase]

Cool car you got there sir. I've switched to the stainless steel exhaust sleeves to keep from deforming the pipes. That makes it easer for future adjustments.

[@AutoAutopsy]

Thank you! Do you mean exhaust clamps?

[@Blutnase]

@@AutoAutopsy Yes sir. Exhaust sleeve clamps. The U-clamps are just cheap and need to deform the pipe to make a seal.

[@ASnomelc]

Sounds great man

[@AutoAutopsy]

Thank you!

[@VioleNFaN]

Exhaust is made by swedish exhaust manufacture Simons and not by Maptun. And the cause of the tip beeing outside the bumper is that the exhaust is made for an flat nose 900.

[@AutoAutopsy]

Hmm. I see on their website it says it can fit slant nose models like mine

[@preamble466]

I see you added the chrome strips to the bumpers after all. Looks good, didn’t look right without it.

[@AutoAutopsy]

Yep, had to do it! I filmed footage for it awhile back and might throw it in as part of another video

[@t.h.9187]

Apparently no one in the comments knows exactly why the sound of the Saab 900 Turbo is so unique. This is due to its exhaust manifold with four paths of unequal length in front of the turbocharger inlet. If you replace the manifold with a manifold of the same length to achieve faster charger response, the bubbling 900 turbo sound disappears. The exhaust you purchased is originally from the Swedish company Simmons and was made for the older version of the 900 with larger bumpers. Therefore, some adjustments are required and the tips need to be shortened. Unfortunately, due to the different materials between the tailpipe and the part above the axle, it is starting to rust. Stainless steel meets normal steel here and corrosion-promoting galvanic currents flow. Unfortunately, the silencer also rusts quite quickly - but the sound of the system is nice. Enjoy it!

[@AutoAutopsy]

Thanks for that insight and information on the unique sound. 😁🙌🏼

[@raffe65]

Very nice sound on those engines. Strange that they stick out so far out. On my 900 Aero back in the 80s i hade Saab original sport exhaust. They where more staight at the back. Think i have a picture of it somewhere. I miss my 900, maybe i sell my 9000 Aero. 😎👍🇸🇪❤️

[@AutoAutopsy]

Nice! I think I know which exhaust you’re talking about 👍🏼😁

[@matejzatko787]

I have JT 3” and thats perfect, the tip looks almost like original and the sound is also very good, little bit louder, but not too loud and little bit deeper sound it has...

[@AutoAutopsy]

Awesome 👏🏼

[@matejzatko787]

@@AutoAutopsy But its crazy, how beautiful sound it had on stock exhaust, that low rumbling, almost like v8

[@dennisjacobsen22]

Sounds Nice, find a metal band saw and cut 1-2" ... think they will cut as Nice as the maptun exhaust end cut. The leak can be fixed whit a small amount of exhaust paste er fire gum... great work

[@AutoAutopsy]

Thanks Dennis! 😁

[@FuckFistingAss7osuFF7osu]

Awesome.

[@AutoAutopsy]

[@coling7091]

Nice job. Are you planning to repaint the hood and tail? Would really finish the 900

[@AutoAutopsy]

Yep! I am going to get the whole car painted eventually 👍🏼😁

[@brettfrantzen7425]

Damn didn’t know map tune did exhausts ! Hey maybe take to a muffler shop to hack off a bit of the pipe 😮

[@AutoAutopsy]

Might have to do that!

[@RockyDE293]

Woow a Saab Ricer 😁😁😁 don't forget to cut a little bit of the rear bumper as the pipe will swing with every gas push...🍻

[@AutoAutopsy]

How is this ricer? 😭

[@RockyDE293]

Because the pipe is standing a little bit out...anyway nice working

[@Juju1503solo]

The sound i so beautiful😍

[@AutoAutopsy]

🙌🏼

[@browserrr1]

Always use montage paste when assembling. The tips should be shortened a bit, this looks cheap while I'm pretty sure it isn't.

[@AutoAutopsy]

I have heard some really bad/mixed things about exhaust paste, so I’ve always avoided it personally. I do wish they could be shortened. It’s growing on me more, but if I get tired of it, I’ll probably take it somewhere and have them “professionally” shorten it so it looks nice

[@TheBTG88]

Could you not cut the exhaust tip from the end that fits into the system and thereby be able to shorten it without cutting the visible end?

[@AutoAutopsy]

Unfortunately not, given how it’s shaped and where the hook hangar connects. That what my first thought!

[@preamble466]

Need to cut 3”

[@thackerybrown2860]

i bet if you cut those down, and then touched them up with a dremel, it could look decently not-hacked

[@AutoAutopsy]

Definitely. But do I trust myself to do that? 😂

[@polarbear3427]

[@AutoAutopsy]

Or just look at the picture. I don’t like to edit mistakes out of videos so that others can learn from them

[@caferacer01]

I know Maptun make quality stuff. But that muffler looks low budget and some of those welds look horrendous.

[@AutoAutopsy]

Not the prettiest welds, but it’s functional at least. I will say the welds on their NG 9-3 downpipe are beautiful though

[@winandd8649]

Tiny exhaust leak, tail pipe sticking out a bit... Astonishing what you can get away with over there. Here (NL) that would be a definite fail at the yearly MOT inspection.

Same with Simmons vs. Stock: Far too loud. Doesn`t suit the understatement-appeal of the 901 to my opinion.

[@gpg3307]

Not the right way to mount. Sticks out to much. But Sound is right. I've owned 4 900:s

That’s how it’s supposed to be; there’s no way to push it in further👍🏼

@@AutoAutopsy No it's not. I know. That's idiotic and dangerous.! You said yourself: you done it wrong. If you did it better from beggining it would be as it should. I know! I live in Sweden and seen 100:s sence the 80;s and owned several.
