would this improve my cars sound? i have the magnaflow mufflers but wanted a little more aggressive sound. is this an option and do they make one for my 07? ty guys

 

Are u gonna replace ur magnaflows with em?

 

is that what id have to do?

 

the loud mouth 1 exhaust that was run on the ls1 fbodys was just a loudmouth resonator with the mufflers deleted. if you have a ls4 car you can take your mufflers off, run straight pipe to the tips. sounds similar to the loudmouth. to my knowledge slp doesnt make a lm1 resonator in 2.5 inch only in 3 in. check there site though that may have changed over the years. also if the goal is to sound exactly like a lm1 ls1 car i dont think it can be done with the way the factory exhaust is with the crossover, and the front manifold dumping into the rear. similar, but not exact. i have a video on here of my car with the magnaflow exhaust where i removed the mufflers, and just have it straight piped

 

ty for the info. im gonna look into that.
