Exhaust Questions

[blackblazer24]

Car is an 03 GT. I've got a couple of dynomax super turbo mufflers laying around. They both have 2 1/4" ins & outs. Can they adapt to this on the in side. Cause I believe the in side is 1 7/8". Also I plan on leaving the resonator installed. With these mufflers will it be annoying from the inside of the car on long road trips?

I also plan on getting the u-bend deleted. How much of a mileage increase can I expect from this?

Thanks

Can be loud. I had a borla and a magnaflow on my old alero v-6. the magnaflow was ok..but kinda loud, but the borla was loud. Not good for long trips. Dynomax's are not bad for sound, i would get the the reguler for sound b/c it will be a little quieter for sound.

Wow that sucks. I read some other dude sayin 3 mpg. Don't really know if that's worth $100.

each has a claim of something. Use your best judgement.

If you plan on just buying a U-bend delete you can get one for about 40 dollars here.
