They are both a straight through design. there is no baffles to slow down the Exhaust flow like a gasser that creates back pressure.

I removed the rear muffler and have better quicker rpm climb and no drone at all. It's only slightly louder.

Can you buy a larger flexpipe and easily fit larger diameter piping all the way back? I'd like less back pressure in my modified wagon...

People have managed to cram a 3inch downpipe in their 617... Just run full 3 inch stainless all the way back, no devices of muffling.

You can save yourself a lot of expenses if you just go with one short piece of pipe.

Ah, okay, I thought you had a turbo car. There is a big difference on some of the pieces for the non-turbos. The center pipe (no resonator) for my CD is listed at $16 at one site.

From scanning other threads on straight pipe setups, the key to no drone is to have the exhaust tip exiting about 1" behind the bumper. If you put it into the stock position, you will get drone.

Matching the downpipe to stock 2.5" pipe is mostly the issue that caused the bump in price at the shop. The extra time would be to fabricate a joint there to go from the stock pipe diameter to 2.5".

Whoa, Charlie, no more coffee for you today.

You ought to know better. I would NEVER paint my hood black. Tch.

Anyway, I was planning on this approach:

What diameter pipe did you use for the rear section, and how did you adapt it up to the center resonator section? Did you do it yourself or did a shop fabricate it?

I am starting to like this idea.

Here is the Ansa web site, maybe get the MB Exhaust system from them.

That's a good one, saw that picture a couple years ago on a search.

That would good in Texas :cowboy: along with the Long Horns on the Hood. :D



Coffee? How did you know I just finished off a full pot? :icon_eek:



The SD with the black hood was owned by Youngbenz, haven`t seen him in a long time on the forum.

He sold it a while back, that was a backup hood from the junkyard. I think these days he's driving a 7.3 powerstroke.

Attention Greazzer (or anyone with the info)
 
Having trouble sourcing the all-in-one exhaust install kit. Looks like I will have to assemble some hardware.

I have found the locknuts for all the associated bolts online. But not the bolts themselves. (The actual spec isn't listed for the nuts.)

Anyone got the spec for the lag bolts that attach the flanges where the downpipe joins the middle section?

For some reason I have about 15 hangers of various flavours sitting around, so that is not a concern :eek:. Guess I must have added them onto several of my group parts orders....

Thanks

Go for the gold.

Is that a church organ instead of a trunk mounted amp and bass speaker?

Zacharias 04-13-2014 08:39 PM

Really, Jooseppi. Like I would put a big ugly star like that on my trunklid.

Who could have predicted that one man's tale of exhaust woe would unleash all the forum wisearses :antlers:?
