Hey everyone,

I was wondering if this muffler (http://www.amazon.com/gp/product/B00029J3IO/ref=s9_simh_gw_p263_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-4&pf_rd_r=07HVXKJ6YJ2QGJNN8X63&pf_rd_t=101&pf_rd_p=470939031&pf_rd_i=507846)

+ a cherry bomb would be good on a 2.4 g6.

also, would i lose any low end torque with this type of set up?

Thanks

Dynomax mufflers sound great with the Ecotec L61 and LE5 motors. You need a glasspack or high flow resonator, and don't go bigger than 2.25" pipe diameter.

The ultraflow is a chambered muffler. I have to find it again, but Dynomax makes a muffler made for 4 cylinder cars, and they sound awesome, especially with a performance resonator.

Chaos have you heard/seen any sound clips online of a set-up like that?

I never got a sound clip, but my friend Lizzy's GA, with the L61 Ecotec motor. She kept the 2" pipping, glasspack resonator, with a Dynomax crossflow muffler. It was quiet driving normally, but loud at WOT.

Keep the 2" pipping and you're golden. Also, if you do add a header, it will become raspy.

Your car is pretty much stock, stick with 2". I'm pretty sure the LE5 models have 2" pipping for the exhaust.
