Hooker or OBX headers and side exhaust and resonated or non-resonated?

<< < (2/3) > >>

69 DIRTY RAT:
obx have great stainless side pipes!

MR 502:
I fitted OBX headers & sidepipes to my 68 a few months back and love the deep sound they put out, they fitted perfect (LHD) and couldn't beat the price about $1250 au delivered to my door no tax, eBay USA. Ill be at the Tuesday BBQ next week if you want to see them. Good luck with your choice. Warryn

Matt G:
Okay, thanks guys. Will be at the BBQ. Keen to look at and hear the OBX Warryn.

Matt G:
Hey guys, I thought that I'd post an update.  After all of our discussions, and hearing a few cars with their side pipes at the BBQ, I ended up staying with my hooker headers and then running a new system out the back. I almost went with a Varex valved system, but apparently they get hot enough to ignite rubber if you don't run them open for long enough. I thought about a "Y" junction and a valve, but eventually I went with a straight through system. Much simpler,  seams to give me a little more bottom end, and sounds pretty nice as a bonus. Not sure how it would go with a noise test, but it's quieter than I expected at higher revs. I'm pretty sure that it would fail any noise check at about 1500 rpm.  It appears to have a resonating harmonic around there that will occasionally bring on an involuntary cough from the vibration, and then a selfish giggle after I realise that it was caused by the sound of the Vette.
Thanks everyone for your feedback and suggestions.
Cheers :cheers:

Matt

rosco:
so no mufflers at all  mmmm that will be interesting to hear. Surprising about the bottom end thought it would have given better top end with a little away from the bottom end.
