Pontiac GTO 2004-2006 - 04 exhaust
02-20-2012, 10:31 PM
Buddy of mine just bought an 04 gto 6spd. He is wanting to put a catback on it. We both really like the Magnaflow and Bassani sound. How well do each of these two perform on an 04 gto? Thanks guys.

I don't neither will increase hp that much. Tell him to go with what one sounds better.

Well, the best way is to go on youtube and pick the one you like the best. I just bought my 04 and I'm probably going to get the SLP Loudmouth IIs. I like it loud but not raspy.

IMO i wouldn't get SLP. The drone of the exhaust of the highway gives me a headache. My question wasn't about the sound but the performance. I mean if the horsepower gains are minimal then go with which one sounds the best. Both sound really good tho so its not an easy choice. But if one system has like 10 more horsepower than the other than thats a clear answer. And going on youtube isn't the way to buy car parts.

Oi. I'm not saying to go shopping on youtube. I'm saying that if there is a certain combination you're going for, you'll find it and know what it'll basically sound like by going on there to hear it.
The exhausts for the 04 GTOs are minimal, if you are looking for a gain in anything, you'll likely have to split them and get an 05/06 rear bumper with insert.
I'm not the "know it all" guy when it comes to this but I have had a couple of these cars and know my way around the aftermarket area pretty well.
As for SLP, thank you for the advice. I will look into that drone.
You won't gain much with a cat back. Get headers and then see if you like the sound. You'll pick up a lot of power and the sound will change also. Win/win situation :)

If I were you I'd go with headers and mid pipe first, then you might not even want the catback

you wont gain hardly anything with a cat back. i would just save up and buy headers and catback at once you wont regret that. i cant post the video since im in afgan. but if you go to youtube you can hear my exhaust clip. go to 98demonZ28 and click on jakes gto. i have stainless works headers and catless mid pipe with spintech x-pipe with the spintech super pro race mufflers 3in center/center dumped off under my car check it out

I just bought the Flowmaster Catback. It is purely a sound thing, they don't net you power. YouTube is the best way to shop.

On youtube I find most GTOs without an aftermarket cam don't sound that good on initial startup. Most of them regardless of set-up sound almost like a European car.
