I noticed flowmaster just released a system for the HHR. Emailed thier customer service to see if they had anything in development for the Cobalt. The rep wrote back to me, said they are working on a system, but no date set on when its available.... I for one am excited for this, flowmaster makes some quality stuff....

 

traditionally, flowmasters sound horrible on the ecotec cars. thats why none of us run a flowmaster muffler. Of course ill never complain of more aftermarket support

 

Well put.

 

i would love to hear a sound clip of a full flowmaster exhaust

 

I would tend to think that putting a muffler vs putting a complete system made by a manufcaturer that tests and tunes thier product would hopefully yield a better sound. I've never met a flowmaster system that I didnt like.. plus, aftermarket support is never a bad thing..

 

well, the piping will all be the same regardless. at the end of the day, the only thing that will change sounds on a car with full exhaust versus a car with a custom exhaust and muffler/res is the muffler/resonator... given that all else is equal on the car
basically, what im trying to say...running a custom made catback with a flowmaster and running a flowmaster complete exhaust will sound identical. again, i hope im wrong, and i will never turn down aftermarket support, but im just sayin

 

I currently have a flowmaster cat-back on my SS and it sounds like poop... Which is why the just purchased the Vibrant Header back from Turbo Tech Racing

 

In my experience, the smaller the motor, the less I want to run Flowmaster. While they sound great on big blocks and pretty good on small blocks, they don't sound too good on V6s and even worse on 4 cylinders. While this is true for most mufflers, it seems even worse for Flowmaster.

 

i think thats the general consensus amongst the rest of the forum as well Matt

 

For the first time, I agree with matt

 

lol. matt's usually right on the level..its Zoomer who goes a little crazy... haha

 

the vibrant header back is way 2 loud by my opinion trust me you'll cring at wot
