Just read through almost this whole thread...has anybody gotten an f-body to sound like a C5 with borla straight pipes. From my understanding "borla" straight pipes setup is just LT's, x-pipe, and no mufflers but it sounds so sick on a vette. I've heard straight exhaust on an f-body and it sounds different for some reason???

Vette guys chime in if I'm wrong about this Borla straight pipe thing...

I'll get some clips up soon

Straight pipe things? Straight through mufflers or what, regular straight pipes is rasp city.

Will TDs give a more "deep growl" and less raspy than Headers, ORY, and a Catback?

if done correctly, TDs should make children run in fear for their life...

but yes, TDs in my opinion give more of a muscle car "rumble" sound (at least when you have it dumped it does) i've heard some good sounding ORY exhaust setups, but i'll never go back to a Y unless my clearance gets so bad that i have to.

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.

I'm actually curious, if the muffler has an internal x in it would the reduce the need for a cross-over pipe? I understand that you still want your crossover closer to the headers, but wouldn't it still be helping out balance and scavenging?

I have wondered that myself. I dont know the answer.

However, by keeping the front X-pipe, I could pull the Magnaflow muffler and install something else like power sticks and maintain an ideal setup.

i wanna see some pics of a universal X pipe system like summit jegs flowtech dumped befor the axel....so i can get an idea of ground clearance and such

Very true. Still sounds good

Is your car lowered? Ground clearance?

My car is at stock height. Lowest point in the pipes is just before the axle. They are still almost 5" above the road. I have more GC now than when I ran the 3" ORY single pipe setup.

Here is a shot from behind:

would this work....using a 3" I pipe mated to a ORY, over the axle into an slp LM, then use the single chamber flowmasters mounted as yours are, having the tips installed directly to the mufflers........

Would of taken the pictures from on a lift but this is all I had to work with at time. 1 7/8 ARH, Straight 3" true dauls with magnaflow race series bullets dumped. I must say this sounds pretty good and would recomend it to anyone. Sorry I have no sound clips at the moment.

CHRRRIS

^^^ My set-up is very similar but different bullets and headers. Straight duals does sound good, but I worry that I am missing out on more power from the better flow of a H pipe. Thinking I'm gonna get one put in next summer.

How would you guys compare a LT/ORY/LM2 VS LT/TD's?

What would sound / price diff be?

I have been on LS1sounds but i dont really like it, 90 percent of the cars on there have a cam so its hard to justify what the car is going to sound like. This past weekend I heard a WS6 that had LT's/ORY/LM2 sound very good with no rasp. If its just as close to price and I dont have to deal with the ground clearance hassle and bending a bunch of tubes ....

Any suggestions??


Thanks!

TSP's kit has a price listed on their site, I forget what it is. I had mine custom done and was north of $700 with 3inch mandrel bends not including my mufflers.

If someone decides that they want a custom mandrel one done, let me know.
I have enough leftover to do a whole system and I'm selling it cheap.
