Well, IF you want the very Best aftermarket exhaust AND you want it cheap AND easy to install, the answer is simple. Not GOOD, but simple. You will need to steal a Supertrapp and header pipe off another Suzuki 650. I recommend finding one with 14 baffles in it.

i got a straight through take off muffler from a dyna, out of the harley dumpster for free! (the chrome was scratched) ??? i got mikuni main jets from a local chopper shop for $2.50, i got the #55 pilot jet from the honda shop for $1.89, i modified the white spacer for free. total cost $4.39, how frugel do you want to be?

Thanks! just learning to navigate the site...oh and i want to be cheap as possible but still have the sound i want. After listening a screamin eagle is what i want. I love an extreme sounding bike. Anyone know of a place to get one with good prices? Cant seem to find them online for the savage. -DOC

A lot of people on the site run a HD muffler (usually sportster ones I think) - much better sound than oem one.

not all Harley stores have cast off mufflers (not the one in my town - they say the people who convert take their old ones away with them) but many on site say they get theirs for $20 or so - much cheaper than a screaming eagle & plenty loud from what folk say. some mufflers have a connector place with a hole in the pipe so you have to get someone to weld it shut.

the site has a how to connect a sportster muffler in the tech section I think - needs a connecting piece with a 10 degree bend in it - the local car muffler store make it for like $10 usually (mine did it for free). you'll need a suitable size heat shield to cover it up if you want to keep the bike pretty - I got mine from a box of old ones @ one of the old school type non dealer type bike places my town is still blessed to have (cost me about $5 against $10-15 for a new one!)

this is way the cheapest to go for a good sounding loud enough muffler (obviously being given & not have to pay a cent cast off HD one from the store is even cheaper!)

although not gospel - bikes do vary - you'll get help on size of jets depending on what muffler you fit & what sea level you are at (what year might not hurt - I don't know) - ask for help here. the white spacer mod is pretty obligatory on these it seems - mine runs fine without but maybe my bike/altitude is just unusual.

one other tip - watch it when you take the screws/bolts out the top (to do the spacer mod) & bottom (to rejet) of carb - they are very soft & can be messed up easily - may have to use grips on them if you screw up the heads. it is very advisable to replace them with stainless steel allen head bolts to make it easy to remove next time.

you'll likely have to drill out the brass plug on the right side of the carb (careful not to drill into the screw underneath to fine tune the carb. read Lancers carb tuning tips in the tech section of site on how to fine tune the carb using this mixture screw - worked  for me when I had a backfire I wanted to get rid of.

I personally have a slash cut hard chrome (double walled so no blueing) mufffler I bought from Lancer - he (used to -maybe still does) have them available for about $70 or so - not as cheap as a cast off HD one - but like I said the place in my town had no HD cast offs available. mine is certainly loud enough & helpful for more power I feel.

oh yeah - HD clamps are advisable - nicer looking than car clamps & better than oem - think mine cost me about $5-6 each. use hi temp - I used orange - permatex to seal the joints between header & connector & connector & muffler & don't start the bike for 24 hours to give the goop plenty of time to set.

you might have to take the header off to get the old oem muffler off it - I did - they were really tight, even after I backed the clamps way off. I used a new gasket where the header goes in the head (I'm a bit anal) but as long as the old one is in good shape you should be good to reuse it. just torque down the bolts on the header correctly - backfires on the bikes often come from exhaust leaks - either here or at the 2 connector joints.

Happy work changing the muffler over.

What Happent JD? That thing was running so good you thought it was a twin?  

Havent heard a screamin eagle, but my dyna muff is pretty loud and rumbles. Maybe we can make wav files of all the different types on a thread and compare...
