mufflers
 

whats a good cheap muffler that will make my car sound better

Or you could go to Walmart and put some muffler tips on.

tips aren't really guna change the sound.

but seriously, you're being to vague. sounding better is a matter of opinion. deep, rasp, loud, etc.

What sounds good is a matter of opinion.

Borla is one of the most universally liked exhaust notes on the rx-8. I just didn't like the piping and that due to the design more soot and flames came out one side than the other.

I tried the OBX exhaust off ebay.....and it compares to Borla $395 for catback system......Thats aout the cheapest cat-back system u will find for tthe 8.....it's a little loud at first start up but after the pipe gets hot is quiets down and sounds pretty throaty....
