Soo doo itt!
I currently run my n/a with a 2" straight pipe with a glass pack for a muffler. You just need to make sure that the exhaust exits from under the car, or else it will resonate under the car and be ridiculous inside the cabin.
It is quieter than my 8v gasser I had on the same exhaust before I swapped motors.
Do it. Hack it off so that its easily fixable and your golden
ive never heard a n/a gasser even come close to being diesel loud..
my diesels have all been so loud that they will make your ears ring after a good wide open pull.. -

Well I doubt our diesels sound any different, my interpretation of the 1.6 na with a cherry bomb and nothing else is much quieter than my 1.7 gas motor. The diesel sound is all from the engine, not the tail pipe.I'll never run a straight piped NA again............
Was it legit straight piped? or did it have any sort of muffler at all? A glass pack will change the tone completely and take it from a droney horrible sound to a nice note, with rasssp. I have a 67 Cougar that we straight piped, true duals to the rear off the long tube headers. Holy christ.. Threw on some $30 cherry bomb glass packs and sweet sweet music.anybody remember the old IDI fords with straight pipes? GOD DAMN they were loud..
50:1 CR will make a loud explosion
TO THE OP, you wanted to do it originally, so doo it man. Go with your first instinct. Just make it reversible if you dont like it the muffler goes back on. Plus you likely have a resonator still, that will muffle some sound. It might sound bad ass.

Response 1.) dude, there is DEFINITELY a sound coming out the tail pipe on diesels.. if you think all the noise comes from the engine, then think, or listen again. sure the clack at idle is engine noise.. if all that noise is from the engine and not the exhaust, then why do EXHAUST MUFFLERS make the engine quieter?
anything else, is exhaust noise. i REALLY WISH you could have heard my n/a with an open header.. gave a new meaning to the term "LOUD". yes, OPEN HEADER on a diesel rabbit, not open manifold..
Response 2.) yes, it was a Legit straight pipe, like came off the downpipe, no mufflers, then exited in front of the rear tire.. it was FUGGIN LOUD!! it would RRRRRRRAAAAAAAAAAPPPPPPPPPPPPPPPPPPPPP right off an idle.. thru every gear. you couldnt drive that car and not rap the pipes..
another thing to remember, if your going to run straight pipes, just remember that overkill on the diameter, is a good thing on straight pipes.. it mellows them down alot, gets rid of alot of the low RPM rap..
Response 3.) ford IDIs never had 50:1 compression, they had like 18-19:1 compression.. our IDI VWs are the highest-factory-compression engines ive ever seen.. tell me that the ford IDIs with straight pipes didnt make any sound out the tail pipe? all that sound was from the engine, not the exhaust?
24:1 (diesel) exhaust is alot louder than 8.5:1 (gasser) exhaust generally.. -

Mine is turbo'd with just a resonator and it dumps out just underneath my backseat floorpan driver side, in front of the lr tire. I love it so much. Has a nice throaty burble when I'm on the skinny pedal and at cruise it has a slight drone that is not bad at all.
I do believe that without the garden snail it would be intolerable. I say do it but like others have suggested, make sure it exits not under the car. Or get a big bottle of excedrin. -

HAHAH! He said make sure it exits from under the car. Even a muffled exhaust not exiting from under the car would have a drone as the exhaust note would be trapped and circling under the car.

You also have a turbocharged engine. which does not apply to which we are referring.
And your a liar
. Same exhaust on my bro's TD, right off the dp, and extended 6"? to point at the ground. There is still exhaust drone inside the car. Comparing to a perfectly sealed muffled exhaust system exiting behind the rear valence.

no, im not a liar, you just have never ran a VNT on a 1.6
VNTs muffle the exhaust easily twice as much as a conventional turbo.. and scream twice as loud as a conventional turbo..
thats why i get away with an 8" long downpipe.. because my turbo is way down low, not up high behind the intake manifold like a normal TD..
yes Jeremy, my car really is that quiet, no drone AT ALL in the cabin.. you hear the intake noise more than from the drone that isnt there..
there, fixed it for ya jeremy. -

VNT on a 1.6? Thought we were talking bout non-turbo engines?
more than the drone from the pipes..
So there is a drone then eh? lol

I have to admit though, I would like it a little louder. Once I switch to the 2.25 DP and 2.25 straight, with a turndown exiting in front of the left rear but out towards traffic, NOT under the car I am hoping I will get that "little moar" loud that I want, and also quiet the cabin down a little bit. I am also hoping that I get that turbo whistle out the exhaust pipe that I have seen/heard on youtube.
Like this one:

This is my car, 2.5 downpipe and 2.5 exhaust with a straight flow muffler.
this clip is a cold start, lots of white smoke, but I've been meaning to capture the sound of the exhaust because i've never had a chance to hear it before.
*edit it was raining when this was being filmed, so there are odd sounds of cars driving by in the rain, behind the camera -

I would love to hear how it sounds warmed up. Why does it smoke so white on startup?
