What suggestions do you guys other there have about a fast and the furious import exhaust sound for a stock iron duke 2.5. What kind of exhaust system should I get fabricated (what kind muffler should I use and What size pipe should I use).

I suggest not doing it.

DONT put a damn fart can on a fiero!!!
its NOT a honda, you Dont make it sound like one!!

a decent sound for the 4 cyl, is remove the cat. and install a resonated tip

So your saying it is impossible to make it sound like that or you just don't like it like that, and your also saying leave the stock muffler, what if the muffler is old and need to be replaced, and what kind of a resonated tip (pacesetter, ....)?

Nothing is impossible crouyer, however, due to the midengine design of the Fiero and how low it is to the ground, it makes things a bit more difficult in comparison to a standard FWD. Personally, I hate the sound and look of the "Potato Launchers", but to each their own.

A Pacesetter resonated tip (or any other resonated tip for that matter) with a hollowed out cat will give ya a pretty good sound in comparison to stock.

As Alice Cooper once said...

quote Feed My.... Frankenstein!

The average "ricer" with a "fart can" does'nt sound near as good as the f&f cars did the f&f cars had a much deeper sound. I don't think you can get the iron duke to sound like the f&f cars because the engines in the hondas, ETC are all overhead cam or double overhead cam and had turbo's. The iron duke is a side cam engine and will not rev like the OHC/DOHC engines. You should be able too get a good sound out of the iron duke here's some suggestions: Remove the cat or replace it with a Hi-flow cat, get a header, get a exhaust system bent from larger pipe, and get a hi-performance muffler (turbo muffler, Glasspack, duel Fart cans,ECT). From the items I listed the most effective one's are the cat and the muffler.When you post anything about hondas or any japenese cars you will probably get alot of flames, most of the people on this forum hate "ricers". I don't mind ricers, at least they try to improve the performance of there cars and they are fun to beat

How about we help him with this question, instead of blast him about his tastes?

Since the dukie is a single exhaust, all ya needa do is find the correct muffler that'l fit inside the space you have.. Try looking for a Greddy, APC, Ractive, DC sports and Injen stuff.. I just pulled those names outta the canadian tire catalog, im sure there are more. and you'll probly want the largest tubing you can get.
But with this being said, It will be hard to do, the exhaust system on these cars is sooo short it wont sound the same. Your money would probly be better spent making the car fast then only sound fast

Ok guys thanks for the help I"m glad some none flamers responded.

I have no idea if this would work, but the area where the cat is is big enough for a fart can, could you possibly put it there, and run some 3" pipes out the back? The only problem I would see would be changing the oil filter, but I really havnt looked into it. But just somehting to think about.

Hey, I've got a "Ricer" Integra, and wouldn't/haven't put one of those exhausts on unless you had something to back it up, like a turbo or at least nitrous, I think that why people including me just shake their head when on of these goes by, there's one guy I always see that actually sounded like an old outboard motorboat, he finally changed it, I must not have been the only on that thought it sounded ridicules, but to each their own...at least you have a Fiero

Next time someone asks for help, don't throw your opinions in his face. We're not honda owners, we don't have to sound like a bunch of critical @$$holes.

get like flowmaster 40series if ya want the last and the hilarious sound?

JUGGALO!!!!

I put a stock V6 Dual exhaust on my Duke and it deepened the sound. It doesn't growl like a V8 or even a V6, but it was pretty easy to do.

would the flowmaster original 40 series sound good, or are you saying it will just sound bad, I just want a good, loud sound.

Oh yeah, it would sound real mean. I have a Borla cat-back on my 2.8, and I heard it from the outside for the first time today. Jesus christ. Its LOUD, a lot louder than I thought.

Hey, if anyone wants a low mileage 2.8, with rebuilt diss, new plugs/wires, and a new starter. LMK, ill be selling mine in a few months. It also has a Borla cat-back minus the cat, and possibly a 3 speed tranny. It has 54,000 miles on it. But including the borla I have about 900 in it. It has a vacume leak though.

lol, shutup man. You know you're trying to rice out your fiero.

How about we help him. I like that,BRAVO! I run my V6 with the stock exhaust and no cat.Sounds great to me.

This won't sound but... I have the v/6 and I took out the cat and added the Flowmaster 40 series and it changed the sound like night and day... It made it sooo much deeper. I can't wait until I get the 4.9L in there... Talk about mean...errrr

ps... Go easy guy's... He just asked a simple question..

thanks guys, I'll probably just take the cat off and put a straight pipe in its place and then put a flowmaster 40 in the muffler's place.

For a low rpm motor like the Duke you are better of emulating the deep sound of old english sports cars. MGs, Triumphs and Austin Healey were low rpm engines with a nice full sound, not the typical hot rod Honda sound so common today. The problem with most of the "Import tuner" exhausts, is that it sounds downright unpleasant unless you are rushing to the redline. The old MGs sounded good just burbling around town (as do V6 Fiero).

The Flowmaster will probably give a sound closer to the traditional sports car than the VTEC rice rocket sound.

Wishes he had a cool sounding exhaust!

i have 3.5 inch from the header back with a blue devil steel pack muffler it's sound deep and not farty everyone i ask likes it you do lose back pressure but im load and deep and it only a 2.5

------------------

dont do it with a 2.5, i took the one of my used mufflers i had on my integra and put it on with no cat (custom bent pipes, $60) and it sounded like sh*t on a 2.5 pushrod motor.... it just doesnt have the revs and stuff to make it sound like a import. trust me, u wont want to do it, it will sound more like a old beatup car going down the road then a race car.

Another thing to be cautious of when making exhaust changes on the duke is making sure you don't screw up the back pressure. These engines rely on the back pressure to make the enormous (haha) amount of torque that they do. I got a new free flow cat, that changed the sound enough. Later I am going to play with an electric cutout going to an otherwise faux dual exhaust that I can open at speed, just to see what it'll do.

On the british sound, what kind of muffler would you suggest for this?
