Exhaust Change 2.5" to 2.25"...
Hey guys, just a quick coupla questions..
Firstly, I've got a 2.5" redback sports exhaust on my EA. I find it way too loud on the freeway, as the zorst seems to be it's loudest around 2500rpm (which happens to be my cruising speed on the highway).
I do a lot of highway driving as I'm up in Sunbury, and to get anywhere, you have to drive on the highway..
Now for the questions.. Oh, and my EA engine is perfectly stock..
1. If I swap to a 2.25 will the droning on the freeway stop? Will I need a system with 2 mufflers and a resonator to stop the droning?
2. Will I gain low end power at the expense of high end power?
3. If I have a 2.25" zorst, how do I get the exhaust to look bigger at the back? Can they put on a 3"-3.5" dump pipe on the end of a 2.25" exhaust?
Thanks, all help is greatly appreciated..
