Reduce exhaust noise ?

[supremeaccord]

Yesterday I I had 2.5 inch piping from the the cat back with a vibrant resonator and dc sport dual tip muffler, sounds good but way too loud on the low end in the cabin. I want it to sound kind of normal at crusing speeds and loud on the highway. Any tips or products to achieve this ?

You can try sound padding on your interior, seen a few write ups for that solution on here. If you want to quiet the exhaust, im assuming that your muffler doesnt have alot of chambering in it? same with the resonator? if that is the case try getting a better version of them with better more complex chambering. i have the same problem with my exhaust set up, im going to grab a thrush rattler to place in my mid pipe. They are pretty much a round stubby muffler.

Put a couple of 12" subs in you won't hear the exhaust anymore I promise. Or like he said you could do sound deadening but it's a lot of weight to add.

i have some subs in there already.

Yeah your right neither have chambering in it im thinking about getting the ultra quiet vibrant resonator just to bring the noise down a bit. wouldnt the thrush make it louder ?

my car has no cat or resonator and a straigh through muffler sooooo anything with chambers will make it quite. thrush has that rep because mostly they are put on a stock exhaust ya know

think it would help as another resonator

That round muffler won't do much for the drone in the cabin. I made a thread on how to eliminate drone or at lease reduce it by a lot. I researched on it and it worked for me and other people. I did a straight pipe exhaust with an 18" dynomax resonator and my custom resonator 2.25". With no mufflers it sounds super aggressive still and the drone is reduced by like 90%. With a muffler the drone would be reduced even more probably. It's not guaranteed it will work but it worked for me and others. If you want to research more on it, its called a side branch resonator. Here's my thread with step by step instructions.

interesting so add another resonator and the side branch or just the side branch

Just the side branch since you already have a resonator. Leave your vibrant resonator there. I had a dynomax resonator with no mufflers and it worked really well for me
