As of right now I have the 18 bullet mufflers from TSP, and I would really like to change up the sound, maybe even quiet it down since I live in townhomes. What I was looking at was 1 chambered flowmasters, would this quiet is down enough to ear a difference or should I look into something else. I read threads that have yes, its a lot different, and no, go with brand z. So, any help would be great.

 

Any other thing that you weld into the equation will reduce noise. unless it is a straight piece of pipe.

 

Agreed. Put another pair of bullets in, and it'll quieten the noise. Or, I'm always hearing how people say they want to swap their Magnaflows and Borlas for something louder. You may wanna check them out, as they flow like a straight pipe.

 

I say borlas period. They are IMO the quietest muffler @ idle and cruise all while still having that chest pounding bass and rumble. At WOT they scream just like bullets(maybe a little quieter but not much) are much more refined sounding and flow FANTASTICLY.

I love mine! They are a bit too quiet for me, but I'll take quiet over obnoxious any day of the week.

 

I can't see how the 1-chambers would be any quieter. Mine were pretty damn loud. Borla mufflers should quieten it down some though.

 

The thing about borla mufflers are they are not cheap. And, do they really flow that well. Flowmaster has that sound(not the 80 series cross flow) you can not replace. I am not planning on sending my car to the muffler shop, I will be doing all the work.

 

Yea, the Flowmasters do have a killer sound. You could throw some high flow cats on it and help quieten it a bit.

 

The only thing about cats, they will take a good 10 rear wheel away.

 

IIRC Borla XR-1's flow between 1100-1200+ cfm.

As far as price goes, you get what you pay for. Great flowing mufflers that are stainless, very well built, and are docile compaired to others. You decide. Do it once, do it right.

 

The 1 chamber flows wont be quieter, just deeper. If your looking for quieter, take a look at the Moroso spiral flow mufflers, they are pretty tame at idle, but at wot, they sound mean.

 

No, It is not that restrictive.

 

hey what are the specs on your borla xr-1 mufflers? (size,part number,price,purchased at?)

 

If you want to quieten it down you are gonna need to use the spiral flow mufflers. They will be alot quieter than what you have now and flow well.

They sound incredible under accleration, but are quiet during cruising

 

Thanks for all the input, Sorry it took so long to get back online. I was just wondering what is the size of the borla mufflers and best sight price wise for these?

 

I'd say 10 1/2" metal-core bullets before the X-over followed by SweetThunders or Borla XR-1's after the X.

 

moroso spiral flows sound nice.

 

So, the round 15 inch XR-1 would be a good choice to quiet it down some and fit up there nice? I found them for 116.

 

My buddy put some of those new Flowmaster Hushpower mufflers on his LT1's dual setup. This sounds very quiet at idle, and really opens up at WOT. My adjustable borla exhaust is louder than his car.

 

spintechs are a good choice also maybe somthing to look into.
