Might go with 4 chrome tips though...we'll see. BTW the x-pipe does not have the perforated core-it's all pipe.

Thanks to all who made the GB happen.

So instead of the Xpipe, they gang punched the mufflers!

This is called the SW X-Pipe and is installed on both my 90' and 91'
The 90' installation is just a few weeks ago. My SW X-Pipes are just a bit different.

Cliff,

Sorry but I'm pretty sure I'm looking at the muffler. When I got my SW Xpipe, it had the gang punched inserts which Al removed. My Dynomax mufflers don't look anything like that. They're straight thru.

They have another version of muffler that is louder and more directly straight thru. This chambered version has a little offset and an air gap to allow resonance into the packing plus the perforated tubes. I can tell already that it will still be pretty loud. I figure I can always go to a traditional turbo muffler again if needed.

my plan is to try and fit LS7 cats I have and go with this cat-back. hopefully putting catalysts back on the car will moderate some of the rumble.

I am soooo confused sometimes......

but on another subject....my X-pipes have the cross plates which mike100 does not have on his.

I have the same version (Offroad)......My SW exhausts are ZR1CHAMSW ......so I guess the same as mike100
And I get some resonance in some gears at some rpms but can shift out of resonance easy.

That SSW exhaust system look's great ! Workmanship is fantastic.
Please post up about noise/resonation.

Frank....I think you were asking Mike.....but.....I just took the 91' for a spin and no real resonance. It is loudest at 2,000 rpm with moderate throttle. It is really nice just cruzing in 4th or even 5th and letting off the throttle in 6th just coasting at 65 is just a nice hum.

Any time you step on the throttle you can definitely hear it but again....from inside with windows up (100 deg F outside) and air on it is very nice listening to

Temperature gage did never get over half way

Going to try that system with the C6 ZO6 flapper's.

I'm setup for next Saturday with my exhaust guy so I should know then how crazy the SW muffs will be. I will be adding the LS7 cats so lets hope for some sanity in the resonance dept.

NPP valves from a c6 would probably be worth it since twin outlet mufflers are known to be loud on C4's.

Cliff,

Can you post pictures of the tips? (installed)

Love to see how they look....
