    The time has come for me to get an exhaust on my 98 gtp, my old one is starting to rust out. But im not sure at all on what im going to need, i was thinking high flow cat, u bend delete, resonator delete, and either flomaster 40 or magnaflow mufflers (i want performance and something loud and deep but with little crackle) and suggestions and opinions would be great.

    id say whatever you do... keep the resonator or at least replace it... you will hear drone like crazy without it and youll probably hear diff... but id say make sure you do put on a high flow cat... these cars just dont sound right without it

    keep the resonator or replace it with a glasspack but don't get rid of it altogether.....the rest of your plan sounds OK.........personnally I like the mufflers on so it doesnt sound like rice...............

    Id go magnaflows And weather or not to keep the resonator is just personal preferance. I deleted mine and car doesnt drone at all and is just a lil raspy under wot
    and the whole thing including ubend delete was a little under 300 and that was new piping from the cat to the muffs
    lots of people say it sounds damn good
