View Full Version : 2 mufflers for cosmetics or performance?
I have a 98 Deville. I need to replace the exhaust system. I noticed that it is a single pipe all the way to the rear axle and then splits into "dual exhaust" with 2 mufflers. If I only install 1 muffler, will that effect the N* performance?

I think it is for both. It looks good and having 2 mufflers probably gives better flowthrough and less backpressure.

Exactly. Factory mufflers are quiet and restrictive so having two medium sized ones would allow easier gas flow than one big one. Plus it looks cool.
