I'm bummed!

So I bought an 89 250 xtra cab 4 wheel drive last week, with an older hypermax turbo. I thought I would run it down to the muffler shop this morning to have it straight piped, only to find that it already is!
Why would a truck with no muffler be so damn Quiet? My 86 with the old banks turbo is louder than hell straight piped. Is this something particular to the hypermax design?

I bummed, this truck is too quiet for me!

it did seem very quiet... wouldnt of thought it was straight piped... my truck sounded louder with a muffler on it... hmm

Your timing is in need of advancing. These idi engines run very quite when they are retarded on the timing. Advance it the "thickness" of a dime. See what that does.

we hooked him up to the timing meter at the meet and he was dead on where he needed to be

The problem is it's a Him and not a Her. Her's are always louder, din't ya ever notice.

take a pic of the exhaust to let us see how it travels, might be able to point out something that is quieting it down, how high are you revving to say it isnt loud enough? I have heard multiple banks turboed trucks and they were way quiet with 3 inch straight pipes until about 1500 or 2k rpms

the turbo will act as a muffler, dont relate it to a straight piped n/a engine

Yeah, Nevada law says as long as we have a turbo, dont need a muffler.

He's comparing it to a truck with a banks turbo.

The old banks kit on my other truck is hella loud straight piped but this old hypermax on the new truck straight piped, is darn near silent.

The turbo works fine and I can hear it spool up, although it doesnt give a ton of boost, I have the fuel turned down right now for emissions testing.

Also check for exhaust leaks.

I don't know how to post pics on here. My banks is the old original on my 86 and was installed in 88. That thing sounds great, even when it starts up, sounds very similar to a first gen straight piped dodge in comparision for sound.

The new truck exhaust runs straight to the back, over the axle and out the side.

Would installing 4" exhaust help with the sound any?

to a different turbo, two different turbos will not sound the same or act the same,

Why would you want to cover up that sweet rattling sound with a loud exhaust anyway? I prefer to run it stock

Actually I prefer both and in my 86, it's the perfect combo.
