oh i know about loud cars. my last first gen was straight piped to a fart pipe. it was terrible lol. my 04 mustang gt had flowmasters. it sounded amazing. the car is actually loud enough as is, but it really sounds like a loud *** buzzing bee. it sounds almost like an exhaust leak out the tail pipe. its really hard to explain the sound of a car over the internet, but trust me, its not good. i guess i sounded to enthusiastic over it just being loud, but i want a smooth sounding hum thats loud. not a rasp or buzz.

I have an rb header to strait pipe (not sure of diameter) to an apex'i dunk. I'm sooo surprised I haven't been pulled over (knock on wood). But been followed for some time. I did not buy the dunk it was on my lancer. I'll buy a good muffler and a pre silencer eventually. I had a Honda tell me he was at 112 db w/ an open exhaust no muffler. I was much louder. I'm nervous about revving to red line because cops will hear me.

mine is some crappy header into 3" pipe into a glasspack and a borla. it sounds pretty good, but its too loud

it was a tad quieter than the stock manifold into a glasspack and a turndown before the axle

not sure what the next setup will be, it needs to be quieter though

Dynatech split flow!! Racing beat street header immediately into the dynatech followed by 2.25'' piping to a 10'' ebay special dump tip muffler that exits right at the rear valence. Both mufflers are SS packed and damn good quality, which especially good considering the dump tip was an ebay special.

my turbo sounded great with 3-inch back to a magnaflow straight through. Very sweet howl at redline, like an old carb'd v12 but slightly less refined.

now with the bigger turbo and SS header I'm running open downpipe till I can get to the exhaust shop, it's bad, terrible really, but not ear bleeding loud.

Custom stainless headers, Thrush 3" glasspack, and 3" medium tone Magnaflow muffler, it's PLENTY loud, but the thrush helps cut down the metallic sound so characteristic of the magnaflows so it really sounds good. Everyone tells me it's hard to tell it apart from a hyaboosa crotch rocket (except that mine's faster haha). Of course It's running a half bridgeport so that changes the sound a bit too.

Borla's sound amazing, but they're more expensive, the build quality sucks, they blow up from backfires, and they XRS are in fact crushbent. XR-1's might not be.

Racing beat makes mufflers strong as tanks and they sound great, but they don't make the most power if that's your goal.
Flowmaster's rot out after 6 months to a year of rotary heat.
Dynomax make amazing resonators, but their mufflers are glass packed and will get really loud with age.
Magnaflows are built like tanks and can take some serious backfires, just ask anyone who's driven behind me. steel wool wrapped core with rock wool filler. FTMFW!

Magnaflow muffler, and 2 dynomax bullet presilencers + a small street port make this sound. Loud as hell but fun.

If you want loud, why even bother with a header?

I don't.

(ahem - I'm kidding...)

You did sound too enthusiastic about having your car obnoxiously loud, so you got a scathing response. You asked for it. I delivered.

I have a RB SP exhaust. Sounds great, does not drone at cruise, and it has already outlasted one FB.

2nd Gen NA header, reduced to 2 1/2" pipe into new universal catalytic, downsized to 2 1/4 pipe leading to Magnaflow muffler.

Nice mellow tone, still gives off that rotary tone, that's well behaved, nothing raspy or tinny. Really waiting for the day I have the money to afford a full Racing Beat system, tho.

I blew out 4 magnaflows in about a year, running them as presilencers. Bunch of crap if you ask me. I'll stick to RB, Rotaflo, and Borla

The more I drive my car, the more I'm loving the sound of the dynatech. I just hope it lasts a good while, I can't imagine why it wouldn't.

I'm also looking to change my exhuast a bit(and i've been looking into the dynatech), i currently am running the original manifold to a Rotary Performance downpipe, to the stock connecting pipe then to a cheap Ebay muffler,
I love the sound difference from when i changed from the RB header the manifold and downpipe but i'm still looking for somthing a little different.
I'm thinking about running a 2.5' inch pipe after my downpipe to a 2.5' inch dynatech and then dump it before the rear axle, should be semi-loud and have a sweet tone.
Which exact dynatech do you have starfox? round or oval? and, have you noticed it getting louder since you've added the dynatech, in other words can you tell if the packings starting to deteriorate? i really want something that lasts.

i redid mine

RB header into 2x2"x31" glass packs into the same 3" borla. the borla needs to go, its sounded great before, but is kinda tinny now. i need something more robust in the back.

the good part is that its almost streetable!

so exhaust 2.0 is ok.

I’m running a s4 turbo 3” exhaust and two large Magna Flows, a nice low end rumble but your not going to want to run it on the freeway for a long time. its far from quiet but i love it and d i would not want it louder. If you go from a 2.5" piping to 3" you’re going to be noticeably louder and loose some tq.
