Looking for good muffler choices.....

In all the years I have been around cars I have only heard a few mufflers that make a 6 cylender sound good. Most just make them sound like the minivan with the muffler missing. Do any of you have any suggestions on what to use to make them sound better? I am looking for something that will enhance or change the sound to make it distinct and not just loud. What have people used?

One of the users on here has a very nice exhaust set up - it depends on what you are looking for though...

RJ (TrepCruzin, above) has a very nice exhaust set up. Really krackles when you get on it. He's got a 2.7, and the exhaust he's running really wakes up the notes it produces with out sounding like a naked minivan... To me personally, it is too krackly - not fart can ricey, but just not my personal taste.

Tom (Shadowvox, I'm sure he'll chime in) is running a 3.5 with an modified LX X-Pipe, two Cherry Bomb Glass Packs (near the center of the car), then two Cherry Bomb Turbo mufflers at the rear, on true dual exhaust. I don't remember his exhaust tubing size, I think 2.5 inch. This exhaust I think personally has the nicest sound of the various custom exhausts I heard at Art's (InTheTundra's) meet this last summer. Nice roar when you get on it, but not obnoxious when at idle. Deep and loud enough that when driving you know it is there.

There's a nice thread on here somewhere with a bunch of options listed and discussed - maybe I can try to find that...

I have a Magnaflow set up on mine, I love the sound, nice and deep at idle and snaps good when you get on it!

To me the Flowmaster 40 series sounds great on our cars. With my setup people have told me it sounds anywhere from a mustang to a carmaro.

I was thinking of running a true dual exhaust with just the cat's and no mufflers, but a friend of mine did that with his 300C and it sounds like a naked minivan.

I have heard flowmasters on V-6's before and I didn't remember them sounding any different, but I don 't know what they were using. If 40 series sound good, I wonder what super 44's would sound like? I want to be able to drive this without that constant interior drone you'd get when it shifts into overdrive. Probably if I ran tips out past the fascia that would cure that problem...

Flowmaster and Magnaflow are two very popular brands that lots of people have had success with on their LH cars.

I personally like the Flowmasters, but am kind of waiting until I can splurge on an expensive system that I really want. I absolutely love borla mufflers and their tone, but man are they pricey.

You're friend's description sounds pretty good, a naked minivan. No mufflers would be painful to listen to all day. If you run true duals at the least use an X pipe and one set of mufflers, minimum. A lot of people actually use two sets of mufflers to keep the drone at cruising speed down.



My car won't ever be done because I'm insane. That is all.

i would try the "dynomax vt" they have little to no drone cruising at highway speeds and still sound good when you get on it.

+1 That's what I'm running, too! It's as close as I've ever heard a V-6 come to sounding like a V-8.
In fact, when the wife comes home in the morning I often mistake the Trep for the Chevy 350 truck across the street. (He leaves about the same time she gets home and both are low-idling backing out of or into a driveway.)

I'm not sure you can have a good Muscle sound, as opposed to a sports car sound, without some highway drone. The Road Runner has a highway drone in the same 1500-2000 RPM range as the Treps. There's just something about that RPM range, = 25-33 Hz, that resonates with standard-sized car bodies (I've even set off a couple of hair-trigger car alarms with the Road Runner ) and I think if you muffled that Hz to much you'd also lose the V-8 growl.
