Put a muffler on it. Or it'll be loud.

Next time your header cracks (if you are like many of us, it is probably cracked now), get a Speed Daddy (eBay banks knock off). I have an Aeroturbine muffler, and it growled a bit before. Now it is loud!

Magnaflow 4x9 oval 14" muffler should set you back about 60$

Looks like theyre doing a shitty job ripping off banks... for 2/3rds the price.

You know those details... allways getting in the way.

You said you don't want it too loud at cruise, but a bit more aggressive when you open it up. Running WITHOUT a muffler will make it aggressive sounding through the entire revs. Mufflers are designed to manipulate that sound through the rev range and throttle.

TL;DR you definitely want a muffler. Find one that makes your ears happy.

I have one of the Thrush welded ones cost me $30 through Summit and I love it. Nice growl but no annoying. Half the cost of magnaflow and IMHO sound the same and built well.

APN header, magnaflow 2.25" high flow cat, thrush muffler. sounded great on my XJ and the muffler was good at deflecting rocks.

I'm going back to a stock exhaust. Loud is obnoxious, on the street and on the trail.

It's not like you're feeding a big engine with a bunch of air. It's a low compression tractor engine.

Thrush turbos aren't too loud, thrush weldeds are a bit louder, depends how loud you want it. A glasspack would be even louder but a lot quieter than straightpiped
