Im running True Dual H-pipe (big difference with the H-pipe) Flowmaster 40 series

[#8trx450r]

I ran two on a 98 Z71 with magnaflow Tips and it sounded very good, best setup I have personally had on any of my trucks, Nice mellow deap tone with minimal interior noise.

yep right here. the 3" duals from factory with a pipe fitted between them ( custom H pipe ) 3" single in/out Flowmaster Super 44s, 3" tailpipes 45'd out the side behind tire, with Magnaflow 4"x12" tips.

 

Love it! I kinda wish I went for the 18" long tips though but its all good. going up hill at 2500rpms sounds like 4000 on my old setup. And its silent inside while coasting, and you can still keep a conversation going from 1000 - 2400rpms. & I still have plenty of backpressure, gas mileage went from 12.8 to 12.6, hardly any loss, I haven't full throttled it yet, waiting until I put 1,000 miles on them.

After install, drive away, drive up, and monitoring the speed and rpms

i was going to throw duals on there but my buddies talked me out of it little bastards lol. single 40 with dual pipes. it is pretty loud but could be louder. im kinda happy i went with the single this way i dont piss the neighbroughs off and if i gotta sneak into some trails it helps not being so loud. plus in nj we got some stupid noise law i would of gotten pulled over. not trying to stick out too much im going to lift it in the summer 8in plus 3in body.
