Supra exhaust VS turbo diesel truck exhaust sound... Am I crazy?

[Datsrboi]

I was at a shop today and saw this turbo diesel truck on the dyno....

HOLY SHIP 800whp on a truck. I also notice the guy had like a 4 inch exhaust system. My question is I have seen 3 and 4 inch exhaust on supras and even then its still louder then these trucks. Not to mention these trucks have bigger turbo, 2 cylinder more, and bigger bore. So why would a typical supra with exhaust that big be louder then the turbo diesel. The guys truck I saw today told me its a straight exhaust system with no cat nor anything yet it was that loud compare to a supra with that same size exhaust.

maybe it's the fact that our cars are comparitively smaller and the exhaust has a shorter distance to travel compared to trucks, therefore being louder. compared to a Cummins Ram 2500, i'm pretty sure my muffler would end somewhere around its axle. a shorter distance to travel would make ours sound louder, wouldn't it? don't flame me too much... just throwin somethin out there.:biglaugh:

diesel trucks don't redline at high R'.

Even then just regular daily driving our supras are still louder. I would love to have 4 inch exhaust system on my supra if it were not for the earth wakening sound.

Most diesel puckups are V8's. Chevy is V8, Ford is V8, Dodge is I6 = Cummins = The best and I want one. Early chevy diesel conversions were chevy small block (V8) gas engines converted to diesel during the period when diesel fuel was much cheaper.

My friend has a 4" to 5" and it is louder than my car. My car screams and gets close at high rpm, where the diesel redline's at 4,000. the truck's a much deeper sound, the supra is more high pitched sound at redline, which could make it seem louder.

the brand new 6.7 cummins is SO quiet, its like a gas engine. the old early 90's cummins sounded like they were rattleing apart. moral of the story, i love cummins diesels. That will most likely be the next vehicle i get.

I make a 4" full exhaust with no muffler or cat on my '05 Cummins....I'd be impressed if any supras on here were louder than it.

Supra exhausts are loud because people who fit them want them to be loud. I have a home made 3" exhaust from turbo back with just a rear silencer (muffler) and it is still pretty quiet.

There is a guy around here that had a 3.5 or 4" on an NA, I bet that'd come close. It's loud as hell.

a guy at my work has a new one and you can barely hear it running, its the most quiet diesel ive heard.

My 2K Cummins is a straight 4" from the turbo back, and it's loud as can be. I make about 400 HP and 800 lbs of torque. My 91 Supra is so quiet at stock I can't hardly hear it running at all.
I can't imagine the Supra being as loud as the Dodge. But I don't try to put a camper on it's roof, and a 20' bass boat on it's tail and then try to drag it across the country!

the new 6.4 Powerstroke's are the same, you can barely tell it's a diesel at idle. That will probably be my next big purchase.

My Supra's really quiet. I hit rev-limiter a lot now that I recirculated the wastegate because I don't know how high I'm revving .

I have a rediculously huge muffler and resonator. I'll try to post pictures of it, but it barely fits under the car.

This is the old one. The new one's BIGGER.

i have a HPF goliath 4'' and its loud. Deep loud tho. I am running open downpipe right now and i think my exhaust system is a lil louder then open DP lol.

i have a 02 cummin with a 4" turbo back exhaust,that has a pretty good size straight through muffler.i can't even here the exhaust over the turbo and motor from inside the cab.my supra is louder for sure and the turbo is bigger then the trucks
