2.4 exhaust

what would be the best way to go off brand for an exhaust on our cars? i know nothing bigger than 2.5". but with cat/not cat? with muffler/no muffler? i like loud so thats not a problem but i DO NOT want any rasp or fart can type sounds.

2.5" with cat. Catless on our car barely helps it imo. Just pick a high flow cat

Dude do not go catless it'll be beyond loud. Just do as other suggested and stick with getting a highflow cat. Get a good header like clear image or zzp along with a 2.5 inch downpipe and hiflow cat and for the exhaust just change out the 2.25 section by the rear axel with 2.5 inch piping and add a magnaflow muffler. It'll sound real nice and you get some good power.

mid length is the best thats what i got . i got it from clear image. you can go shorty header but you wont get as much hp.

I've got the ZZP midlength setup with a high flow cat with a 2.5 from mandrel exhaust systems. Increased airflow Magnaflow muffler. I put it on and it was loud and raspy as ****, so I added a Magnaflow resonator and it sounds like SEX. Awesome setup IMO. Decent gains and sounds great, loud with no rasp

I got the same exact setup with a Borla muffler from MES. Has a deep mellow tone. It turns heads without people looking crazy at you. Using an 18" Magnaflow resonator. I love it!

4-1 header its better for high end power. And yeah i heard mandrelexhaust.com make decent stuff for the price. Just make sure you get the resonator 18 inch well be just fine.
