I'm about to have my rear mufflers replaced for some extra sound out of the car.
Couple of quotes I've received are-
1. a pair of Hitech stainless steel dual tip mufflers $980
2. Cat back X-Force SS $850 or mild steel $475 (single tips I presume but I'd prefer duals. I'm not keen either on what some have said are 4" tips on their x-force)
I've read several times of x-force owners mention drone on the highway.
Would this be the result of the centre muffler being changed as part of the cat-back package ?
On my last Lib, an 03 2.5, I had just the rear muffler changed to a 'sports' one and it was great.
Would leaving the centre muffler stock reduce the likelihood of droning noise on the highway ?
I'd like to do this right the first time.
Thank you.
