I have an offroad H on my 97 with an otherwise stock catback. It sounds great with the stock mufflers, and is plenty loud for me. I definately wouldn't want to run flowmasters with it though. That would be painfully loud, with rediculous drone (IMHO).
The power gain with an offroad H is more than marginal, It is actaully quite good for the money spent. How else can you spend under 200$, less than 30 min installation and gain 15hp? I gained .2s and nearly 2mph when I made the switch on my otherwise stock 97. The factory setup has 6 cats, and if nothing else, you get about 30lbs of weight savings.
Anyway, I highly recommend this modification. The midrange is where I noticed the most gain, and that extra torque is just fun.![]()
Exactly.
Most guys love the loud exhaust of an offroad midpipe and aftermarket mufflers. It's too much for me.
On my 97, I ran stock mufflers with an offroad h. Perfect sound, much louder than just aftermarket mufflers with the stock pipe.
Dumping the stock mufflers with an offroad mid pipe also sounds great, but you will draw attention from the noise and not having tailpipes from the cops.
...less than 30 min installation...

I agree with the stuff you said, but I sure wish I could swap mine out in 30 minutes. I haven't found an inspection station that will pass my car (fails visual). So maybe with an "annual swap program" I will get my time down to 30 minutes.
Oh, and yes, an offroad H pipe and Flowmaster 2-chambers are pretty damn loud.
i have a o/r h and flows and it does not drone all that bad if any at 60mph it might just be me but i dont think its all that loud. i have heard a lot louder.
i dont think mine is loud enought for me i think im changing out the h pipe for a x.
