V6mustang2004

hey guys dont let the name fool you i created this account when i had a v6 and now i have a v8. i swear to god im not lying!!

so what i wanted to ask was whats the best catback to add on?? but the things im looking for is a loud sound, improved performance, better gas mileage, and a price thats not to high but not to expensive. maybe from like $350 to $400 maybe a lil more.
let me know any help would be awesome

thanks!

You'll get a million different responses. Go to youtube and search "mustang exhaust" and figure out what you like the best. Your not gonna get better gas mileage, improved performance, and loud sound out of a catback (dont believe the ads). You need to change your midpipe if you want loud and slighty improved performance.

Get the Flowmaster American Thunder 40 series cat-back. $369.95 in Mustangs Unlimited catalog for 99-04 GT/Mach I. Sounds great, have it on my 2002 GT and my 97 GT. It says Flowmaster cat-backs will give you about 1 mpg on their website, idk though.

not to many mods that will give you performance and better gas mileage. the two are like oxymorons
