GMMG is loud and sounds great. As far as decibels, nobody I know has a decibel meter. Not really a standard automotive diagnostic tool.

All I know is I heard GMMG in person and compared it to my bassani true duals. GMMG loud>>Bassani loud.

I have the Bassani with the large 10" muffler, which is suposed to be the quieter of the two they offer. It's louder than I'd like it, but prolly because my car has gutted cat's, LT's, and H/C. (Keep in mind that I like my street cars quieter than most people. I'm an old fart.)

BTW, IIRC Futral sells Bassani...or was it Vinci? I think it was Vinci lol.

Power peak gain is minimal true duals over the Y pipe set up like GMMG but someone from FL (Mr. 223, I think his U/N) dynoed his car w/ borla and bassani and has posted the difference between the two. IMO, true duals > Y pipe set up on sound, torque, and power.

Go Bassani. GMMG is way over-priced. Just glorified straight pipes (I love saying that). You will have more tq than a ypipe.

Unfortunately, the only way to get a good sounding catback is to pay for it. People can talk all they want about the cheaper catbacks not sounding too bad..etc...but bottom line is nothing compares to GMMG and Corsa in terms of sound in catbacks.

Now duals is another story, but then you run into clearance issues and rattles.

How can you say that? Sound is just like taste or sight.

You can get a Magnaflow for example is it made well? Yes it is. Does it add HP? Yes it does.

Someone might love the tone of a 300 buck Hooker setup way more then a 1300 dollar crazy custom dual job.

To me and others GMMG is just not the best tone out there.

As said before, peak gains near same, gmmg will be louder.

Bassani duals have no clearance issues, and when assembled properly don't rattle. You are talking about wives tales, or low-time poorly designed setups. My Bassani system was perfect, and sounded better than any catback can. Not to mention the gain in power...

I figured when someone asks which sounds better, they are looking for opinions. I thought that the fact that good sound is subjective was common knowledge?

I never argued that duals don't sound better. I just stated that if you want a good sounding catback (implying Y-setup), that you only really have two choices.

I'm sure the Bassani setup fits just fine...I would expect nothing less from a pre-fab setup. However, if you want to mate it with LTs (and really what's the point of duals without LTs?), it's going to cost just as much as a good y-type catback setup.

GMMG, its a lot easier if you get headers later down the road.

What are you trying to say? Usually a good ypipe setup costs LESS than true duals...if you want to play you have to pay.

And fabbing the bassani to fit headers is a piece of cake. Any competent exhaust shop can do it in just a few moments, with no issues.

Not true. If you get headers later down the road, you then have to buy a ypipe that fits your headers. With the bassani kit, it can be modified to fit headers in just a few moments, instead of having to buy anything extra.

With the Bassani True Duals, when you are switch to the headers you will save $$$ by not having to purchase the Y-Pipe. However, You will need a set of 3 to 2 1/2 inch reducers. I used the flowmaster reducers. They were about $50 a set.

My car has the Bassani True Duals with Hooker LT Headers (no cats) and it is very loud at WOT. I wouldn't want it any louder.

If you don't have headers, either exhaust would be a nice sounding setup.

Good luck,

Al

P.S. Because of the X-pipe, I had to switch from the SLP Driveshaft Loop to the BMR.
