I've got a problem at the moment with my car being way to loud it hurts your ears after driving. its 2 in system from the extractors back with a fairly short hot dog and then a fairly free flowing muffler on the back. i want to build a drop tip glass pack muffler like you would run on a rotary, the plan would be to make it fairly large, pack it with stainless steel wool and then muffler pack.

 

I don't know if i will be going backwards with trying to get it quieter, i don't know how much just a standard muffler would restrict the system. it has shaved head, 32/36 weber, huge cam and so on. it moves a lot of air, so i don't really want to put on a stock type muffler to cut noise down and lose flow. i know there's always heaps of topics bout exhausts but i have the standard system every one says to get and is way to loud. i know there's kinda of a science to it to get maximum torque and power. i just don't know where to start 2 inch might be the wrong size all together. does any one know how to do all the maths to work out the perfect exhaust system for power wise and could still be quiet?

Good post, you told the people playing at home almost what they need to know to help you.

 

Tell us what engine and chassis you have and pehaps people with similar equipment will be able to field your question.

 

Cheers.

I've got a ke20 5k. Heat wrapped extractors and a 2in system straight through to a 18inch Super Cat glass pack with a chrome angle cut tip. Not that loud, but everyone knows when your giving it daboot.

Well it's a ke70 panel can with 4k shaved head, huge cam, 32/36 weber has 4 into 1 headers in to a 2 inch system with a hot dog and free flowing muffler. Would a glass pack muffler quieten it but keep it free flowing?
