H Pipe or X Pipe?

I currently have neither but have read enough that I'm gonna visit my muffler man. What do you recommend? My setup is medium cam, 2-4bbl carbs on a crossram manifold, MSD electronic ignition, headers into 2 1/2 exhaust all the way back. Currently have glasspacks so it's very loud. I'd like to reduce the noise a bit while pushing max flow. Thoughts guys???

Re: H Pipe or X Pipe?

I like the X-pipe it has a different sound to.

Re: H Pipe or X Pipe?

Thanks Skip, appreciate your reply. What different kind of sound? I'm mid 50s age so the old school dual exhaust brings back memories but it's just a bit too loud. I'm a bit hesitant to go either H or X as I don't want to end up with something like a single exhaust sound and then want to change back. Any description of your sound would be much appreciated...

X pipe will make it quieter and you'll gain a few hp up top.

I have 3" one chamber race mufflers on my 67 Camaro and they aren't as loud as the 3" super 40s I have on my 74 'Cuda, but the camaro has an x-pipe where the cuda doesn't have any balance pipe.

Sure but its a BBC 498 and with the X-pipe it will quiet it down a bit.

Re: H Pipe or X Pipe?

here is a sound clip of mine that was shot from inside the car with one of the new Go Pro Cameras. It was filmed at night so you can't really see much. You'll have to turn up the volume a little bit. Sounds great with a set of external speakers.

Re: H Pipe or X Pipe?

I just installed a Magnaflow Stainless Steel 2.5" Exhaust System with the X-Pipe in my Chevelle. What a difference. It still has a very throaty tone, but it is quieter at idle and normal driving. At Wide Open Throttle, it sounds awesome.

Re: H Pipe or X Pipe?

I don't have any data, but it seems an X-Pipe would flow better since it would better equalize the exhaust pulses before it hits the mufflers. The mufflers are where flow is impeded.

Re: H Pipe or X Pipe?

Check my sig below for a sample of what my x-pipe sounds like.
I went from glass packs to Magnaflow duals with X and I love it.
Listen to the whole thing and you can hear some medium range throttle.

Re: H Pipe or X Pipe?

I have a x pipe and I wouldnt go back to a h pipe or true duals any day of the year. At idle it is quiet but you can hear your cam. Normal driving its smooth! When you want to put your foot down it just has pure awe power when you hear it singing. All of my friends like it and they wish they could put a x pipe on there cars now. You wont be sorry.

P.S. And Pypes makes a x pipe with cut outs already in there x pipes for the same price as a non cut out I do believe.
