When the weather gets better I may ask =Jeff= or PW to help record a flyby at full bore. Al took it out from his shop while Pete and I stood by to listen and you could here it going down the street and Al having to back off due to tire spin.

This is a no frills exhaust just the basics long tube headers,full 3" pipes,X-pipe,no CATS.

This exhaust is all business but tame enough it won't give you a headache.
It's a beauty and the beast exhaust.

Still a B&B exhaust then, right?


Sorry, couldn't resist. I'm stepping away from the keyboard......................

Dom/Pete,

Thanks for clarifying and it makes sense about the double walled tips. If I remember correctly the B&B are only rolled edge but still a single wall design. Darn, those Z06 might be harder to find, cut off and then shipped to me and also wondering about how to connect the flapper on the 90MY where the charcoal cannister is in the front and not the rear; not sure what vacuum sources are easy to tap into. I like the Mr. Gas 4" tips that are double walled. I might not mind just a beast, but touring long distance when I do could drive me crazy or give me a headache. Thanks for all the input and guidance.

If you notice the prototype B+B that LB posted have the B+B shape tips but they are double walled.
BTW, nothing against the Dr. Gas stuff but the tips alone are $60 ea. You could find complete Z06 tips w flappers for that or a bit more.

Dom,
Yes, I noticed that and those are very nice....but I don't even dare ask them how much. It seems to be the going price of high quality double walled tips but, yes I am considering that with the total price of tips in mind. I'll still in search mode, but also have to figure out how to tie in the flappers or go electronic control (even more cost). Thanks again for all your help.

Craig,

Flappers are connected via vacuum line running to the D/S plenum port. You could run a separate "hard line" (plastic) to the rear of the car and then T to both flappers. I'm going to look into an ECM control we might use to energize a solenoid which would then allow vacuum and activate the flappers. With larger cams this would help control valves from flapping open/closed when larger cams are used resulting in oscillating idle vacuum.
Could be dictated by TPS v or %.

Dom,

Thanks for the explanation in terms that even I can understand. I'll look into the Z06 tips to see what I can find and make a decision with all things considered. I love how your car sounds and it sure is both wicked and nasty sounding at the same time.

Anybody ever check out the Akropovic system/ tips? some of the Z06 guys run it

John,

Thought you might get a kick out of seeing this. I finally scored a set of Z06 muffler tips w flapper valve and we installed them on
a pair of DynoMax 17228 Ultra-Flows. I think the muffs and tips make the LT-5 sound pretty nasty. I would welcome your reaction.
