A friend has a 7.3 that he runs "uncapped" and i love the sound. Its like putting your ear to a shell and hearing the ocean except all you hear is Turbo!!! My question is can i do this to my 03 HPCR? If so how close to the turbo can i eliminate the exhaust pipe?

 

just straight pipe it. depends on where you are located, you can get a ticket for being too loud. if you cut the pipe too close to the motor, all your going to do is get VERY loud and have a ridiculous amount of drone in the cab and cover your entire undercarriage with soot and make a mess.

 

Like said above, if you want a nice sounding exhaust, just straight pipe it. If you really want to hear the turbo, search the ****** Whistler posts on here. I did the mod and WOW!...its almost too much whistle.

 

I ran just a 4" downpipe on my 1st gen when I installed a Super 40/35 hybrid and couldn't make it to my friend's muffler shop for about a week. I even drove to my sister's place which was about an hour drive. It was certainly loud, left a hum in my ears and a tingle in my feet for a while after that.

That said, I only ran it that way 'cause I had to. I wouldn't want to have it that way for good. I would straight pipe it and look into a different intake as everyone else has said.

 

Jimbo,
Are the pics from before the muffler shop or after? My friend owns a muffler shop so i can do anything. Straight pipe all the way to the back? Somewhere in the middle? just tryin to keep cost down cause everything on an island is F@#%&**n expensive.

 

Before, of course lol. That was just the downpipe with a turn down tip I have.

 

thats wat i thot. straight pipe all the way back? or is it just a matter of preference? and is that how i tune the sound? has anyone experimented with this?

Thanks guys!!! My last post was not even answered

 

you cant tune the sound, straight pipe means just removing the muffler and putting in a "straight piece of pipe" to replace the muffler,

 

Um yeah but i cant very well put in a 20' piece??? Guess I meant: tune the loudness or resonance. BTW isnt an organ tuned by the length of the pipes??? I know my question seems elementary but I was just looking for some input. Thanks guys for ALL the comments
