Here is the soundclip. Also went over speedbumps with no scraping. I dont scrape anywhere. So to anyone who said you cant do under the axle without sacrificing clearance find a better shop

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" reducer cones
Magnaflow stainless (5) J-bends, (4) L bends and (1) 45 degree bend
Woolf aircraft (2) 2.5" ultra tight 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 clamps

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.

Looks great! Sounds pretty good too. I'm not a huge fan of the Magnaflow sound but good job none the less!

Nice - with that setup there's a lot of variety in regards to proper combinatoric.

WRD that sounds great! What was the total bill for the whole setup? I'm going to start saving my money

Not counting the cutouts, about $600 but I got all the pipes, clamps and muffler at cost. Average Joe might spend $1000 for all the stuff again minus the cutouts. I also sold my Borla for $500 so I got a lot of bang for the buck. Cutouts were another $350 IIC.

Lots of cool setups in here.

Two questions. Has anyone gone from a Borla to a true duel setup with some bullet mufflers? I would like to compare the loudness from say a borla with the open plate (essentially unmuffled) to a true duel set up. I would not think a true duel would be louder but I don't know.

Secondly for the TA's out there, the bumper cutout looks off without any tips for those that do the before the axle dump. Any solutions to this?

True Duals are not necessarily louder, but are deeper.

My duals with two bullet mufflers are every bit as loud as the cutout I had previous to this setup, but part throttle is MUCH more quiet.

How bad is the vibration when u guys dump the x pipe before the axle?

iTrader: (3)

did you get this done at a shop or in your garage? Im looking for someone in the kentucky indiana area that can do a quality dual xpipe w/ 2 bullet mufflers and a cme around that price range....

I have pacesetters with tsp true duals and the vibration isn't too bad

Do you have any sound clips that you can post up?
I'm thinking of building something similar to this setup.

i have a question, i just got true duals put on and it sounds amazing! the only problems are that at idle it feels like my head is going to pop from the drone/resonance... like when you roll one window down in a car kinda thing. my turndowns actually point at the rear end and i was wondering if i could remidy the problem with turndowns that pointed further towards the ground and out a little

secondly around 1500-1700... everything shakes.. something i shoudl just get used to or what?

thanks!

Here's a couple clips, theyre not the best but it's all I have as of right now..videos dont do it any justice though, easily the most wicked sounding ls1 exhaust! Skip into the last video a little..Hope it helps!

Has anyone been able to or tried to get the sound of a vette out of a fbody.
