Ok, I have 3 inch true duals with Dynomax Race Magnum mufflers, I can barely hear the car running at idle, I just dont know if its going from a single muffler to 2, but going to dual 3 inch should make a deeper sound. Looking for something more aggressive sounding. Whats everyones preference.

It must be your mufflers. Mine are pretty damn loud and IMO sound amazing. I run the Dynomax Bullets BTW. I have heard many different mufflers on TD setups on the LT1's and they pretty much all sound really good. Just comes down to personal preference.

I'm trying the Flo Pro Twisties out..there is a guy on here that has them and it sounded pretty cool.

I know there is quite a bit of difference between my setup and a LT1..but it should sound close.

you are probably going to get every answer possible in here. its best to just watch as many soundclips as possible and go from there

Hey:

How about Moroso spiral Flows, you can even get them in polished stainless steel?

I really like the sound of them.

I have finally finished the true duals project for my 1995 Z28. The entire system is stainless steel and was made from Magnaflow mandrel bent pipes.

Here are the specs:
Flowmaster 3" to 2.5" reducers
Magnaflow stainless (5) J-bends, (4) L bends and (1) 45 degree bend
Woolf aircraft (2) 2.5" radius L bends
Magnaflow dual in/out (internal X) muffler
Magnaflow X-pipe
Magnaflow stainless dual oval tips
Dynomax stainless cutouts
QTP electric cutouts
Lots of stainless Accu-seal almps

I designed the cutout pipes to be easily removed and replaced with catalytic converters should the want or need ever arise. Takes about 30 minutes to do this. Also the whole thing can be easily removed rather easily just like a catback.

All pipes are stainless MIG welded and ground smooth for a seamless look. I polished the rear pipes exiting the muffler to a very shiny finish as well.

The exhaust sound is deep with absolutely no signs of rasp, popping or machine gun sounds in the 2K RPM range like what I had with the old Borla catback and ORY pipe. The sound volume at idle, as well as WOT, is similar to any other catback. Definitely not overly loud unless you open the cutouts. Maybe this is due to the Magnaflow X-pipe up front and the internal X-pipe in the muffler. The exhaust waves should certainly be balanced with this setup.

Ground clearance is outstanding with the lowest point being ~5" off the ground. This is on the pipes just before they go over the axle. I have yet to bang a pipe.

I also managed to reuse all the factory exhaust hanger points to secure the new system. I only had to custom make one new hanger, just in front of the axle as well as the pair at the tips. There are also stainless O2 bungs welded into each reducer for easy hookup to the wideband O2 at the dyno.

Thanks to everybody who offered help and advice with this project. I could not be happier with the final results.

Dynomax bullets!
This was my really **** poor ground clearance but awesome sounding dual setup. 2.5" h-pipe with two Dynomax bullets. I've since gone to a single 4" also with a Dynomax bullet.
I start the car 2 minutes into the video for those lacking patience.

They are amazing sounding

I am running a 2.5 x pipe with 20" powersticks and I personally like it more than the cars I've heard with the bullets. But then again, that's me.

Nice, im getting a pair of those. These summit turbos drone like a **** 1200-2000rpm. It's annoying even with the sound system pounding.. Do these drone at all?

Mike, IMO one of the best LT1's I have ever heard. Sounds perfect to me, luckily mine sounds the same just in a stalled auto haha!
