I want to put on a pair of Magnaflow mufflers only, on my 02 V8. My local dealer says he would sell me a pair of #14325 and installation for $450.00 Canadian. Sounds a little pricy as I have seen them on ebay for $87.00 US. Has anyone that has installed just a pair of mufflers liked the improved sound ? and did it have any adverse effect on the car's performance. The dealer said there would be low cabin noise with these. I'm looking for a slight throaty sound only. I don't want to hear a rumble all the time as I drive especially on the highway. Any comments, thanks.
