Quiet, free flowing exhaust

[ryztriumph]

I'm looking for the best flowing exhaust for my GST. It's stock now, and I like how it sounds, but I wouldn't mind to have it be a bit louder than stock. I don't want it to sound raspy and high pitched like Hondas around town do, more like low and rumbly. I was thinking of going with a 3" downpipe and then 3" catback to an Ebay N1 Muffler. I need a cat for inspection, so I don't really want to mess with that, and I like how my stock exhaust looks. Dual tipped. The N1 is so tacky. Also I could probably spend about $300ish.

This guys running straight back to an N1 and it sounds pretty good. I can't really tell how loud it is from the video, but I like how smooth it sounds!

Any ideas?

Ive personally never seen a fartcan that quiet. Anyways...

If you want something quiet, go with a 3'' in, dual 2.5'' out muffler with 3'' Piping. you could look for kits, or just buy the muffler and have a muffler shop weld together some tubing.

If you want something loud, go for a Thermal R&D 3'' Catback. Loud, Rumbly, and Free Flowing. And, as an added benefit, it doesnt look like a fart can.

If you want something loud and you dont have much money, you can get a cheap 3'' fartcan kit. The sound can vary on fartcans so you wont know 100% what it sounds like until you put it on.

I would suggest fabbing up an exhaust using 1 or 2 Magnaflow mufflers.

My exhaust has a low rumble and isn't loud at all, like what your talking about. I've got an RRE 2.5 to 3" dp and hi flow cat. And the apexi n1 catback. So similar setups should sound similar. This is a bit more expencive than your buyer though.

Nearly all the cat backs for our cars have a low drone from 1800-3000 rpms. So your basic normal driving rpms.

Mine is driving me insane. I am trying to sell it so I can fabricate something that doesn't drown out the radio and conversation unless your on the interstate doing 75+ never quite understood why it makes less noise at higher rpm.

The ebay n1 worked really good for me, not loud at all, and it was cheap

LiquidX does your have that terrible 2-3k drone where your passengers can't understand they need to speak the #### up for me to hear them? Thats the thing I hate about mine, its not loud really, just has that low pitched drone around cruising speed.

Liquid, that sounds pretty good. I am kind of worried about the drone though. I don't do much interstate driving because it is so boring. Most of the time my car is in between 1500-3000 rpm. Best gas mileage. I wouldn't want any droning as it is my daily car.

There is drone and you will pretty much never get away from it, it's all from the fact of pipe size, material used, muffler volume etc.

The drone isn't as bad as it used to be with a single muffler. If you want to completely get away from it, I would suggest having a 3" down pipe and the stock cat back exhaust while utilizing an electric cut out off the down pipe.

I was thinking of using a rather long glasspack. I had a 36" glass pack on my saturn, and it idle low and rumbly, but it didn't have that stupid highway speed drone.

I am seriously considering going with a 3" downpipe to a cutout then stock cat back. I just don't want open pipe off the cutout so I am going to have to get creative.

I have 3'' turbo back with 36'' Cherry Bomb glasspack and Dynomax supper turbo muffler(17744). It's nice and quiet when cruising and not too loud when i get on it.

You guys who are posting combinations of resonators and/or mufflers that have worked for you need to also say where each component is located. How well a given component helps to reduce drone, etc, depends on where it is. For example, to reduce the drone in a 2G set-up with a big T28, RRE 2.5" - 3" downpipe, 3" cat-back with straight-thru muffler will melon-blaster, I needed a resonator almost exactly where the cat had been. In contrast, on the Evo X, the resonator needs to be further back.

It's all about resonate frequencies and such. You could do the math from scratch, but best would be people posting the details of what has worked and not worked.

A cutout would be pretty fun but is not really what I'm looking for. Okm, do you have any videos of your car with that setup on it? I'm just trying to explore some different options. I guess I never thought of using two mufflers before. Our triumph has two mufflers on it and it's still super loud.
