Thread: Which Cat-Back to go with????

I'm wanting to get a cat-back kit for my 2005 GTP and i'm torn between the SLP Power Flo cat back and the Dynomax Super turbo Exhaust system all i want to know is which one sounds deeper and if anyone has these exhausts on a 2004 and newer grand prix put a video up thx

Just get mufflers. The entire catback is a good waste of money.

Which ones do you recommend??

It's up to you just do some youtube searching. I wouldn't go with a cat back unless yours is effed. I went with the SLP power flow, i got rear ended and it bent the resonator and effed up the mufflers, and love the sound, but it's up to you. I was going to put flowmasters on mine before this whole ordeal happend

I youtubed the SLP it sounds pretty good i just want something to give the car a deeper sound and i dont know whats the best way of going about it

youtube 03bluegtp or bluegtp03 or whatever and look at my exhaust vids.

Catless Pacesetter Headers/XP Cam/3" Custom Catback with the stock GM Resonator into Flow40's

ive got an slp powerflo and it does sound nice but as stated above if your pipes arent complete garbage, like mine were, then just do mufflers

Awesome? Sounds like butt.

i read that dynomaxs get much louder ovetime as the fiberglass inside wears out. those were my 2nd choice but went with magnaflow instead. both sound good

It was sarcasm. You said a catless header with no res setup sounded good. I posted that to show you that it doesn't.

Good video. Glad I have resonators.

so do you guys think just getting headers and mufflers would b best (mayb down pipe)??? What mufflers should i look at getting too???

If you buy headers...your getting a DP.

I covered exhaust options in my safely modding thread in my signature. Read it...and go watch those vids. Catless headers and a stock catback will make your car sound pretty good...then if you want louder and a better tone, toss some mufflers on the stock pipes.

isnt there a muffler sound thread on here somewhere?

you could also youtube "modded grand prix gt magnaflow" or "grand prix gt magnaflow" and find the image of the rear end of my car. Magnaflows have a nice deep tone to em.

Borla

Borla muffler would fit on my 05?? Any particular model??

find a local exhaust shop and ask what they have or can get for your car and pricing

no need for a catback unless its messed up
my exhaust cost 300 basically it was catback cause my piping was rusted when i got it
I like magnaflows and borla but its all opinion and youtube doesnt do any exhaust justice

Sure borla will fit, not sure what the inlet is on 04+ but probably 2.25
