Guys my trans am has 3" true duals, x pipe an a set of summit 18" glass packs. Car sounds amazing but its way too loud. How much more noise reduction would i get with moroso spiral flows or a set of spintechs? car has no cats, longtubes and 12.0:1 compression. Reason for having to change to something lil quieter is my neighbors have called the cops on me 4 times in the last 2 weeks since i completed the build.

hmmm classic chambered might be a better way for you to go. you can get them really long and they do help to quiet them down. your best bet however would put in a second muffler in place of the stock muffler. duel in duel out with the bullets. i run a set up like that on my camaro but its a single exhaust. but its nice and quiet.. when i want it to be

was hoping to keep my true duals trying to find something a lil quiter for my set up. anyone know how much quieter moroso spiralflows are than bullets?

the spiralflows really aren't quieter then the bullets, just not as raspy. at least thats my opinion. i would find something with more of a chambered design then a straight thru desigh like you have.

i wasnt saying get rid of your true duel exhaust. just route it in the stock location and put another muffler in line.

I would toss in extra mufflers or put in a chambered 24 inch to bring things down. Cats would also work.

how do you route an x pipe true dual exhaust in the stock location on car that runs singe exhaust from the factory?

who has a 24 in chambered? i was looking at the 12" chambered spintechs. if the thing wasnt so raspy it would be great. So any suggestions?

Hey:

I added 2 Moroso spiral flows to my loudmouth and made it a lot less a cop magnet even went to Mrytle Beach with it and they have some of the most strict noise laws in the US. But I have cats also, they work pretty good when you get on it, but pretty quiet when not.
