Title: New Exhaust
Post by: Tim Kelly on January 05, 2009, 05:13:26 PM
Soon I plan on getting the exhaust pipes done on my 69 300 from front to back, but I have had some discussions with which mufflers to use. Me and several people I know all agree Flowmasters are the brand, but I'm in between on going with the Super 40's or the Super 44's. When I listen to the sound clip on their website, they sound almost identical.  I'm going for the deep sound with the HP rumble. Would anybody hear recommend one over the other?
One more thing.....I am also considering adding  "dump" exhaust with electric switches so I could scare the piss out of the tuner guys when I pull up next to one. Would this be overkill ? I have no idea what the cost to add the dumps. Any suggestions ?

Dynomax Super Turbo.
People tell me that my exhaust sounds awesome.
I have a 440 with some mild upgrades and TTi 2-1/2" system.
I heard the Flowmasters, and to me they sound too much like a Chevy or a Ford.
The Dynomax do give a true Mopar sound,IMO.

Ya think the Ultra Flo SS mufflers would be too loud?

Your car sounds good Cbarge. I think I'm going to have to go talk to my muffler guy this week, who also happens to be a Mopar guy, and get his opinion too.
He did a nice job on my Imperial back in 07.
Dynomax is certainly an option now. Thanks

Make sure the exhaust extends past the body line or at least reached the bumper or valance.  It will keep the cabin noise down.

I would stay away form the flowmaster mufflers...you'll end up with a nice drone in the car while cruising...plus they just don't sound right.
 
I have 2 1/2 dynomax super turbos on the wagon..off factory HP manifolds and the car sounds great...on the family vaction in the wagon last summer the wife and kids never complained about the exhaust noise while cruising for over 1000 miles....(http://www.moparfins.com/forum/smileys/smiley2.gif)

If you're sold on Flowmasters, go with them.  I think they are too loud and used Turbos on my car - but to each their own.

Post by: Stan Paralikis on January 06, 2009, 11:45:25 PM
I always use Flowmasters 40's.
The deepest rumble comes from the regular "40 series".
The "Super 40" and the "Super 44" are quieter.

Electric cutouts are pretty cool but expensive.....

They don't sound like open headers but they do make it known you're there!   a friend has em' on his 65 Belvedere 426 Wedge car ( motor change coming soon).    

we've got Dynomax Super Turbo's on 6 cars around here,  had 1 friend bound & determined to use Flowcrappers.....he got the 50 series & was sorry he did.    Drones bad between 40 & 50 MPH. 

I put Flows on My dart with the TTI system almost 10 years ago....didn't keep em' a year. switched to Dynomax & never looked back.

If you want the same sound but a bit louder the Ultra Flow Dynomax is the one to get.  the Ultra's are about the same at Idle & Cruise but they really "bark" at WOT compared to  the Super Turbo's.    Super's run about 45.00 to 50.00 for a large case version &the Ultra's are about 80.00 ea.   

The other thing is that even the Super Turbo's are proven to outflow a Flowmaster & the Ultra's  flow even better.    Borla's flow even higher & sound good too but are real expensive.

I've used Accurate for my exhausts systems before.  Excellent pipes but the mufflers they use are no great shakes.

My '68 Polara had Blue Bullets, AND a nasty attitude (http://www.moparfins.com/forum/smileys/smiley2.gif)    I don't know who made them though.

Post by: Tim Kelly on January 07, 2009, 06:02:19 PM
Looks like the general concensus is Dynomax. I can honestly go with any brand as long as it can get me to the sound I'm trying to accomplish, and as long as my car doesn't sound like a Phord.  I have heard the Dynomax mufflers sound better the longer you have them on the car, which would be a good thing, since I plan on keeping this car a while.     My exhaust tips will be different than factory though. I plan on having the tips at a 45 degree angle, pointing down at the corners of the rear bumper. I did this on my Imp and it looks cool when it's warming up.
damn, I ramblin here....I was on the internet last night and came across some website, DXM, MDX, or something like that, (I should've save the site) but there was a complete dump kit for $179 for both sides, and there was even a couple video's on their site that showed the functionality of their product. It seemed to be quality stuff and not a bad price, but I can't find this site again. Anyone ever hear of this company or know their web address?

While it is not a C-body,it is a Mopar just the same, my 99 Intrepid ES with the 3.2 V6, had the exhaust replaced 2 months ago to a true dual exhaust, using a Cherry Bomb dual inlet/dual outlet(muffler also has an X pipe inside) has a great rumble to it when I jump on it and a great back down when I use the autostick and hold it in gear.

I'd be interested in hearing that Tom.  I've never much cared for the sound of V-6s with custom exhaust, but I'd sure like it if my 3.9 Dakota sounded more like a "real truck."  But I don't want to pay for something and then be dissapointed. 
 
I did hear a 225 with the split exhaust manifold and FMs once in Sacramento - it did sound good!

Your right again Snotty!!! I've always said GOd is a Mopar guy, I've never had a Mopar show rained out. One time it rained but it only lasted about 30 min. then the sun came out and it got HOT!!!

After thought here...in addition to the new exhaust system, I thought this would be a good time to locate and add a set of HP exhaust manifolds. Will the HP's line up with the standard 440 exhaust manifolds or should I get the HP's first before spending the $$ on the exhaust?
Title: New Exhaust
Post by: Ken on February 04, 2009, 03:47:28 PM
IF you can find 'em, get the hp manifolds first, because the outlets are at different locations than the stock logs.  That's what I have done so far...might go the TTI route next, or have an old salt muffler shop guy do up a system for me.


Title: New Exhaust
Post by: Snotty on February 05, 2009, 08:40:25 AM
Yes, stock manifold outlets point straight down; HPs point rearward.

I really lucked out today!  Located a nice set of the HP exhaust manifolds with  the heat riser parts still working from a good ole boy, and he was only 30 miles from me.
I have been convinced from the replies to this post to go with the Dynomax Super Turbo's with 2 1/2 pipes. I can't wait til the weather breaks, so I can get the 300 to the muffler shop.
Title: New Exhaust
Post by: Snotty on February 17, 2009, 09:45:22 AM
Make sure that those HPs don't have the usual cracks on ther backs by the collector.  If so, they can be repaired, contrary to popular beleif, but these manifolds are commonly cracked, especially the passenger side.
Title: New Exhaust
Post by: Tim Kelly on February 26, 2009, 03:41:19 PM
I stopped by the muffler shop today (without the 300) and the tech said I may have to start out with 2 1/4" pipes from the exhaust, then further back, change the pipes to 2 1/2". He said I might have a clearance issue with the 2 1/2" pipe near the engine and steering.
The HP manifolds point down with a rear facing angle compared to the stock ones. I know TNT fuseys had this set up, but I have never seen one close up. Anyone have pics of this area?

I was reading a post on the Dry Dock on HP exhaust manifolds. I read the left side (drivers side) HP's for the C body is specific to this body. Is the casting number 2806900 or 2883409 for a '69 440? If I have the HP from a B body, can it still be used or will either manifold work?

Title: New Exhaust
Post by: Ken on March 02, 2009, 04:34:54 PM
I don't think it will work due to the B-body manifold outlet being where the steering column will be...interference fit is a no-go.

Thanks Commando1! Once you gave me the right casting number, I checked eBay, and low and behold there it was, in the parts section when I did a search under "HP exhaust manifolds".
After the left manifold arrived from Oregon, I had both exhaust manifolds hot tanked, and then painted them. After the logs were replaced with the HP's, (didn't know the manifold studs went right into the water jackets...what a mess that made), I needed to decide if I should drive to the muffler shop, which is around 5 miles, with open exhaust, or have the 300 towed. Concerned of burning a valve, I called my AAA membership and had it towed for $0.00. Now the exhaust sounds great and the additional horse power is noticeable.
Right after I got the car back, I changed out the old Hercules 235/75R/15's for the BF Goodrich Radial T/A's 235/70R/15's. At the same time, replaced the dual point ignition with the Mopar high performance electronic ingnition kit from Summit.
The 300 now starts better, rides better, and sounds alot better!
