I read somewhere that you can delete all exhaust on these. ? They said to straight pipe it and it gives a really nice hum. Is this true? It's a 1990 Bus.
Deleting everything as far as just replacing the Y pipe and back with straight pipe. But if your exhaust is in good shape, you can just delete the muffler and replace it with a straight pipe. Straight pipes on these trucks sound like a big block gasser at high rpms. They sound really good and do have a throaty hum to them.I read somewhere that you can delete all exhaust on these. ?

You can delete all the exhaust on anything with the right attitude.I read somewhere that you can delete all exhaust on these. ? They said to straight pipe it and it gives a really nice hum. Is this true? It's a 1990 Bus.
Sorry.. I was just having visions of your bus with big chrome dual stacks.. 'cool bus across the front. (and Elvis style sunglasses on the dash)
Do you like to ride a Harley with straight pipes? Do you ride it around constantly and take it on long trips? If so, then I guess you'd like your N/A IDI with straight pipes. Personally, I don't like either. Here's something else that I've noticed. When I first got my 1986 Bronco, it had a 302 with wore out glass packs on it. The exhaust ended right in front of the rear axle. It was pretty loud inside the Bronco. After I put the 6.9 in my Bronco, I took the exhaust that had been on there and put it on my Red Truck (81 F150). It doesn't sound nearly as loud on it. I think it has to do with the exhaust exiting underneath the cab of the bronco versus under the bed of the F150. I would think that since you have a bus, it would make the exhaust seem to be even louder that it would on a truck. I would say the same thing about a van.
My idi bronco is straight piped and is also obnoxiously loud inside, it's not bad at all under light acceleration and cruising but hard acceleration and under any load at all it is very loud. I was honestly planning to do a single in, dual out flowmaster with some old skool chrome megaphones exiting on either side of the receiver hitch. A lot of people like the way the straight pipe sounds though ,I have been complimented several times and even flagged down twice by people wanting to know what setup I have and both times they were absolutely flabbergasted that an idi with no turbo sounds like it does. I tell them it's the high compression which seems to go right over their heads.
there are lots of videos on youtube, just search 7.3 idi straight piped.Do you have a video that I can hear?
