exhaust

hey guys, I'm tossing up whether to put a duke 390 underbody GPR power core on or the new GPR ghost line. what do you guys think is better? sound and power wise?

Hi, does anyone know that if i put more packing in my exhaust muffler it will quite down the sound? My exhaust is ridiculously loud and was wondering what my options are. cheers

I NEED THIS GONE ASAP OPEN TO OFFERS. Selling this exhaust system due to wanting to upgarde my bike. Fits KTM RC 390 2014 onwards. Located in Adelaide South Australia 5081. This exhaust is amazing, unique sound, loud and punches out way more power. Not a mark or scratch, only been used a...

have any of you guys seen the GPR Ghost Line Exhaust system? looks pretty promising, for those wanting to keep the original look of the RC belly pan exhaust. not a fan of the huge GPR decal on the factory exhaust outlet though, but the cover plate looks good. https://youtu.be/weUSBQ-cFk0...

I have a new in box Akrapovic exhaust for sale. I opened it and looked at and that's it. I didn't even unpack anything, just looked to see if everything was there. Will sell for $800/obo. It's just sitting in my basement. If you need pics .... let me know but it's the system from KTM

Just wanted to give the group a heads up. I'm developing an exhaust that will replace the stock exhaust can but maintain the stock location. My intent is to be able to develop an exhaust that will meet (or maybe even exceed) the Akrapovik system, but not have a big can sticking out the side to...

Wondering what this hose is on the left side of the bike just under the fairing. It looks like is came loose and has been touching the exhaust and now looks all melted. I've attached some pics, anyone know what it is?

Just as an FYI for the group... I've been working on developing a new exhaust which will ditch that huge stock 5.2kg boat anchor of a muffler and replace it with a new muffler which will still fit into the stock location. This primarily means no huge can hanging off to the side of the bike to...

While I'm waiting for my new exhaust to be made, I thought I'd cut open my stock muffler and see if I could modify it for better flow and sound. First thing I noticed after wrestling it off? IT WEIGHS A TON!! I haven't actually weighed it, but I'd guess its 12-15llbs! I then cut the outer shell...

Does the duke exhaust fit the rc???

My Arrow pipe arrived today, so naturally I installed it tonight. I ordered it from an ebay seller called acrmedics, I paid about $540. He was very helpful and communicative; seems like a good guy. It seemed like a good option relative to the Akro system. I have had Arrow pipes on other...

I Just got finished doing the first service and when I was taking the two bolts out of the right side mount that goes into the muffler under the exhaust outlet I immediately noticed they were not the same and one of them had a spacer on it. I noted which came from where but am wondering if...

By now I am sure most of you have seen this: 403 Forbidden Although it kills it on the dyno, our ride finishes a disappointing third based on the reviewer's view of weak suspension (ostensibly caused by the position of the exhaust muffler so close to the rear shock, creating a heat sink - as...

i'm wondering if there's a way to preserve the look of the stock exhaust but make it louder. not offensively loud, but just louder:confused:

I plan to road race my RC390. So I have ordered the F1Race exhaust and muffler hanger from Fuel Exhausts in the UK. Nothing against the kit Akraprovic parts but I wanted something different and it seems like exhaust changes are not giving a huge horsepower improvement for non-kit race bikes. If...

Question: My dealer says that KTM told him that the Akra exhaust can be installed with the stock belly pan. Can anyone confirm or dispute this? I would guess that it'd have to exit through the stock opening by removing the heat shield like others have done with the Fuel. Anybody know?

If you've upgraded your exhaust and are about to bin it, I am interested in possibly buying it! I really like the look of the hidden stock exhaust, not so much the sound. So I'm thinking I'd like to modify it. I haven't seen pics of the stock can (suitcase?) so I wont know what direction I'll go...

The following is not really a specific question, just sharing knowledge/experience for others getting their RC390 race ready, specifically in CA: I was looking into getting the KTM Hard Parts Akrapovic exhaust and the dealer here in CA is refusing to sell me the exhaust (even though this will...
