Re: Straight Piping 99 Grand Prix GT Coupe *HELP*

i would advise against straight piping. sure, delete your cat if you want, but your car is gonna sound like crap without a resonator or mufflers.

yeah see my girlfreinds uncle is going to do it... he will take off the down pipe and remove it and use a straight piece of pipe and weld it on... but he said it needed to be bent?? or soemthing..... i think that would be costly... he is also replacing one 02 sensor and i have an emmulator...
 
Why would you replace the o2 sensor if you have an emulator...unless you mean your replacing the top o2. Also...nothing needs to be removed DP wise...he just needs to cut out the cat/u-bend...weld in the piece of straight pipe...and done. Zip tie your emulator to your frame or something...and throw out your old rear o2. Problem solved.

Your uncle is correcr. You need to spend much money on it. But one way to lessen your expenses that if you have an acquaintance that gives you discount. :D

I see the labor...but parts? LOL Cut out cat...gut it...reweld.
