Before I consider a 3" exhaust (and all the cost/problems associated with it), I want to try the other mufflers. When I had the stock exhaust manifolds and cats, with the Loudmouths, I didn't have this sound. It was just plain awesome then. This started after the LTs were installed.

Yeah try those mufflers they should sound good. I want long tubes! I had them on my old mustang and I loved the performance difference. So would you recomend the Dynatech's??

don_w

Yes... the Dynatechs are made very well and fit great. They went in a whole lot easier than the stock stuff came out. It's a nice set up.

Firedude

I am in the same boat. Waiting to here how you like them. Otherwise, back to stock.

don_w

They are scheduled to arrive on Monday.

Here is an update on my "unacceptable" exhaust sound.

Tonight I slapped on a pair of Magnaflows in lieu of my Loudmouths. I have mixed emotions on the swap. On the positive side, they did take care of that annoying trumpeting and the "bap-bap-bap-bap-bap" is gone, so mission accomplished. I couldn't deal with that much longer. On the negative side, the car is sooooo quiet now, especially at idle and low rpms. It sounds OK at WOT. I'm sure it's louder than stock, but after running with LMs for several months and then getting to hear it with open headers... this is a dramatic change for me.

So for now, I'm going leave it with the Magnaflows until after the Kenne Bell gets installed. After that, I may watch for some other "pre-owned" axlebacks to test out.

Bottom line: I'm glad the mid-range trumpets are gone, but I miss the volume.

Trying to find that Happy Medium

Exactly... but I'm not sure what I should try next. Something similar in design to the Magnaflows, but louder.

duh.....borlas.... lol

I wish someone would post a clip of lt's, h pipe, and borlas. i am dying to hear that combo, as it is what I will be running somewhat soon

don_w

Which Borlas? The straight-through design ones I've seen will probably trumpet like the LMs do. Does Borla make a fiber packed muffler?

SixtySix

In fact they do.

The Ford Racing ones with an "A" at the end of the part number are a chambered muffler.

don_w

Hmmm... I wonder if they are louder than the Magnaflows??? Might be worth checking out.

Maybe someone out there has a set they are looking to sell? Or even trade for a set of Loudmouths?

SixtySix

Well the only one I've heard is the V6 one, it's chambered and to be honest sounds a lot like my straight through ones. It makes a V6 sound pretty flippin cool

Tony, when are your headers expected back from getting coated? Once you get them installed, I am going to find a way to sneak out of work the next time you guys go to the track. I really want to go with a set of long tubes, but do any of the companies that are selling them right now offer a H pipe setup rather than the X? Originally I was planning on going with the Dynatech's but the tubes seem to big for a street car that will not see a blower. I am planning on going the N/A route with ported heads and cams. Don you said that the low end torque came back when the cats were reinstalled?

SixtySix

Jon, they're getting back from coating either tomorrow, or Thursday. If you are looking for a bolt-on H with cats, then JBA has your setup

I just don't like the price... but oh well

don_w

The only time I felt like the torque was down, was when I was running it with the open headers. And once I put on all the exhaust piping from the header collectors back, the torque felt fine to me. It will still bust it loose on the 1-2 shift, and bark the 2-3 shift.

SonicGT

i just added the jba headers and hpipe and they have the trumpet sound to them. before the jba headers i had hookers with a prochamber and borla and that sounded sweet. loud, deep and with a nice rumble. sounded mean. with the jba headers and all , it sounds quiter than before. im thinking of adding the prochamber again to this setup

SixtySix

What happened to the Hookers?

SonicGT

got shipped the painted ones and so they got rusted. i bealive by adding the prochamber it should stop that trumpet sound do it. didnt know what you guys were talking about till tonight. at idle if you revv it, it sounds mean

tom281

Don't forget about Bassani too. They're pretty close to the same design as the Magnaflow but louder.

Yeah sure, I'm alittle partial.........but that's why I bought them over the Magnaflow. They're deep too, even with an off-road H.
