Air intake and exhaust. Is it worth it?

[jimmyjamson]

Hi!

I have upgraded my rig with another air intake at a very early stage. The snorkel w/ pre-filter and proper intake system to offer the engine cleaner air at roof level (in comparison to the dusty air on bonnet level) as I go quite often to remote areas where to expect sand, gravel and dust.

I always recommend to not just look at a snorkel because it looks more fancy but to take into account the whole air intake. I see many rigs equipped with a snorkel bu the rest of the intake is stock and in many cases still not sealed. From my point of view it makes only sense if the whole intake is properly sealed.

Same with the exhaust, the whole chain starting with the intake, including components like a 6.7 Powerstroke upper intake manifold, and ending with the last exhaust pipe is a complex system. It's better to get proper advice and quality products from professionals familiar with your specific vehicle rather than adding something just because it looks or sounds good.

I'd focus on the intake and exhaust only after getting the essentials sorted. A quality intake and exhaust can improve airflow and give you a better sound, but the performance gains on a mostly stock FJ are usually modest. I'd personally put the money toward suspension, tires, and recovery gear first. If you do upgrade, choose quality parts and don't expect huge horsepower gains.

yeah it's worth it on a JK if you're already doing the hemi swap or just want the sound. the intake gets you maybe a few hp, nothing you'll feel in daily driving, but the exhaust is where you actually notice a difference. mine sounds way better with the cat-back. just don't expect miracles on the fuel mileage lol. not 100% on the exact numbers though, go check dyno threads.
