Exhaust on GTP

i have a 1999 GTP and i have a buddy that can put three inch exhaust from my cat back for $100 without mufflers..... Should i do this? what kind if any, of side effects will i have without mufflers ??, and finally, has anyone heard a gtp with only 3inch exhaust and does it sound good? much help would be appreciated :-)

Re: Exhaust on GTP

Ive got 3" exhaust from the downpipe back w/ a hooker aerochamber muffler. Sounds pretty decent. If I were u I would just use the 100 and get a 3" downpipe put on and leave the catback alone.

Perfect exhuast (in my opinion)

TOG headers
3" downpipe
3" cat / no cat
cut out either manual or electronic
followed by the stock cat back

i would do it, but get rid of the ubend also at the least, a new downpipe would be nice also with a high flow cat, keep the stock mufflers they do not restrict, without mufflers your car will sound pretty loud (never heard a 3800 w/o them tho)

on a gtp i already thought i have a 3 inch down pipe to my cat, and i am keeping the cat on, and deleting everything from the cat to the back of the car including the u bend of course, i was mainly wondering if i didn't have mufflers and just a cat, it i would be haveing a backfire problem
