Glad someone else noticed that too.

Yep that's not a 1970 but it's a good looking car, just too raspy for me.

Right cause 1970 isn't the year for big 5-mph bumpers.

It's a shame guy's don't even know what they're pushin!!!!!!!

Prolley told them it was 70 so they wouldn't have to put cats back on! lol

leave it no crossover and add glasspacks instead imo. 👍

​@@muaythai193h paip

@@eviljesus6111 no

yea needs atleast 2.5'' with an h pipe

exactly. i would've done 3 inch at and an x pipe but thats just me

That's a 1975, not a 1970. C'mon, everyone knows 5-mph bumpers started in 1973, right?! Haha! Anyway, I guess they figured with no mufflers/restriction so go with smaller pipes, but way too raspy/sounds like a broken muffler on a really beautiful car. To each their own. I don't 'get' the muffler delete. Cam certainly isn't stock. I would have done 3" with an H-pipe with 2 Magnaflows then choke to 2.5" over the axle and 2 glasspacks as resonators. He'll be back to 'fix it'....

@@chiwowowo The Olds 455 wasn't huge in hp, this one is probably just .040 over with a small cam and maybe basic aluminum heads, which would be ideal in a big heavy car for torque but doesn't make a lot of top end power so 2.5" all the way would be plenty. Hopefully he had the block machined to expand the oil passages, these are notorious for oil starvation at high rpm. And personally, I probably would go with the short case Dynomax Super Turbos. Those are quiet enough you wouldn't need resonators and would keep this thing fairly quiet like the big slow luxury car it is.

This car is a Buick 455.@@AdmiralRustyShackleford

Real clean homie 💯

I hope you put a crossover pipe and some Mufflers on the thing that sounded horrible bro lol.

It was just a test I put flow masters on her. Sounds amazing now

I also put a different cam and lifter set in her she loop an chop something nasty now 💯

No cats, too old. Plus carbureted engine

I doubt that it has egr so even if there were cats on it they would melt and may even be exhausting flammable oxides which would still produce a flame but you would probably only see the flames at night. But it's much safer set up this way.

@@jonathanryan2915 Many carburetor engines had cats from the factory. Started in 1973, this car had one from the factory!

@@Meatwad.Baggins This car had EGR from the factory with a cat.

@@BobSmith-mc7uq Oh wow. Ok. I wasnt sure if egr was that old. That would be something for me to research.

2.5 would’ve sounded similar but better of course with a lil better/deeper pop to it oh yeah and of course a lil bit more hp/tq just from being able to breathe better lol 2.5in aluminized pipe, gutted cats with mandrel bends and this would’ve been an awesome sounding car!

It probably would have sounded better without the long tube headers

Yeah, pretty sure that’s a 1975 model.

Have to agree. 75 and 76 were square headlights. Does look like the 76 I had.

@@keithwagner7754 If you look at the grille closely you’ll notice that it goes under the headlights, the 76 grille doesn’t do that.

Agreed

Absolutely right! Dual 2.25 is too small for that cubic inch, even if it's not pushing big power!

I Was Going to Say the Same thing...he Definitely Need Some Different Gears 3.42's Would Wake it Up

His Kick Down Cable is Not Hooked Up..

Definitely a H-Pipe

It sounds awful

You are right! Bigger pipe, mufflers of some kind.

Flowmaster 40s were made for that!

Agreed! And 2.5 Inch pipe!

exactly, glasspacks with smaller diameter tailpipes sound nasty mean, and the smaller diameter tailpipes gives it that badass pop and snap. Had a 400 pontiac and requested it when I had the packs installed, they were 18 inches of music, installed, it never disappointed. After the install, just could not keep my foot out it to make those nasty pipes bark, damn, miss that car.
