The stock 2004 Pontiac GTO has around 350 HP, but there are tons of ways to boost that number! Upgrading the exhaust system is a popular and effective start. I went with a Borla cat-back, and it made a noticeable difference in both sound and performance!

Totally agree! I had an old GTO and installing headers was a game changer. It really opened up the flow and made a significant difference in horsepower. Plus, it sounded amazing!

I’ve also heard of people using cold air intakes. Does anyone have experience with that? I’m curious about how much power they actually add.

I installed a K&N cold air intake on mine and it definitely helped! I noticed better throttle response and a slight increase in horsepower. It’s a solid mod for the price.

Don’t forget about tuning! After I did a custom ECU tune, my HP jumped up by at least 30. It really optimized the way my GTO runs after the exhaust and intake mods.

That’s impressive! What kind of tuner did you use? I’ve been thinking about getting one but want to make sure I choose a reliable option.

I used HP Tuners, and it gave me great results! Just make sure you have a good understanding of tuning or get a professional to help. It can be a bit tricky if you’re new to it.

What about superchargers? Has anyone added a supercharger to their GTO? I hear they can really crank up the HP, but I’m worried about reliability.

I love my supercharger! I went with an Edelbrock kit—huge HP gains, and I’ve had no reliability issues! Just ensure you have supporting mods to handle the extra power.

A supercharger sounds awesome! I’m concerned about the cost, though. Is it worth investing that much for the performance boost?

If you’re serious about performance, it’s worth it! Just consider your daily driving needs. If you use it for weekend fun, go for it, but be mindful of the added maintenance.

I’ve kept my GTO mostly stock, but I’ve done some minor upgrades. Sometimes I think about going bigger but see mixed reviews online about reliability issues with supercharging.

I understand the hesitation! Modifications do come with risks, but often, it’s about how well you maintain your car after upgrades.

That’s so true! Sometimes the fear of complexity keeps us from enjoying our cars to the fullest. It’s all about balance and knowing your ride.

Has anyone tried nitrous? I’m curious if it’s a reliable way to temporarily boost power without going all out on mods.

Nitrous can definitely be a fun option! Just remember, it’s for short bursts and can stress the engine if not handled properly. It’s a thrill but has its risks!

The 2004 Pontiac GTO has about 350 HP, which is solid for its time. It was one of the highlights of the muscle car revival, offering great performance compared to many rivals.

That is true! It competes directly with the Ford Mustang and Chevrolet Camaro, but many GTO fans argue it has a more refined ride.

I’ve driven the Mustang and Camaro from that era. The GTO felt more balanced, especially during cornering. Those 350 horses really pull well!
