Engine condition

Guys, I recently changed my exhaust but the car is making a really strnage sound and it doesn't even sound like a rotary...
I would like you to hear it and tell me what you guys think of it.

<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/KCIxgnvIDrU?fs=1&amp;hl=pt_PT"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/KCIxgnvIDrU?fs=1&amp;hl=pt_PT" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>

Did you go from a stock exhaust to a true dual setup?

It's most likely just the completely different exhaust design.

Yep, definately sounds like a rotary with duals.

You are getting that nice NA bumble bee noise. You might want to throw some resonators in there to get rid of that high pitched noise.

That sounds really loud in a bad way and really slow. Wouldn't true duals make the car slower?

You just need some presilencers (resonators) installed to get rid of that "rattle can" sound.

Not at all.

Different porting jobs and power goals match with different exhaust designs.

Streetports will often benefit from true dual setups, while bridgeports are more suited for a collected design... it's a pretty complex matter, there are many things to be considered, hehe.

Well, i'm going to install a presilencer ASAP.
Thanks for your oppinion guys, i was affraid it might be something bad with the engine...
BTW, about the car being slow, I think my aux ports are not operating because i feel heasy hesitation over 3500rpm. I should take care of that soon

I remembered when I had my first true duals. I only had a Dynomax ultra flow muffler on and man was that thing loud.
I love the sound though, the muffler gave it a very deep sound and the sounds of the exhaust pulsating out were music to my ears.....till I went deaf from the loudness LOL

Thats the sound of rotary rape..... I can't believe those are RB mufflers, they are extremely loud and annoying. You definitely need a good pre-silencer or muffler of some sort.
