H-pipe power gains w/my combo??
 

I was wondering if it would be worth the money installing an aftermarket H-pipe given my present combo of edelbrock heads, pulleys, headers,dynomax mufflers and e-cam. I still run the factory H-pipe with the front cats hollowed, and the rear cats removed. Would I notice any difference,over my modified stock pipe asides from sound??

Straight h-pipe or off-road (do you have to worry about emmisions?)? Front/rear cats??? You lost me. Anyways, IMO, I wouldn't choose that as my next mod. I'd go w/ gears, pulleys, subframe connectors, and intake, before I swapped out for the new h-pipe.

Blaster,

I'm in a very similar situation to yours. I've gutted the front cats and removed the rear cats as well. I know that I'm not going to spring for a new pipe until I get my combo finished.

As far as power gains, you will probably see a few hp due to the exhaust not becoming so turbulent in the hollowed out spaces where the cats used to be. Also, if you did an X-pipe, you'd likely pick up a few more and a great sound to go along with it.
