Default True duals on Lt1 what size pipe

What size pipe does everybody use with a true dual system? I have L Ts mufflex y-pipe and borla 3inch plate system. Do the true duals and the bullit muflers sound that good to change my set up or is there some horsepower gains going to the duals? How much? <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

It doesn't always mean it will be loud if you run 3" it depends on the mufflers.

Hey man whats going on??

I don't know if you remember or not but we met over at AutoSpecialties one day this summer. I have the blown green Z in town.

If you want you can look at the true dual 3" exhaust Greg made for me. It just has 2 DynoMax bullets on it. With the blower and the 383 my car was very loud...the cops didn't pull me over but I don't think they cared to much for it either.

Shoot me a email or something I'm usually around.

Been a while.

Well if you didn't read on the CamaroZ28 board...I broke the front of the crank off. I never did get it tuned right. I had a fuel problem but I did get 370rwhp and 450rwtq at 3000rpm so it was on its way.

I'm currently getting the car back together now. I think it should be ready by spring break or so. At least I'm working on it. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Just about any muffler will be quieter than a bullet.The borlas are alot quieter than the bullets but there are still alot of other good mufflers out there also.

Yeah I remember ya.

Last time I think I talked to you, you were just getting the motor built for the Firebird, and I had just started collecting parts for the 383 build at that time. Probably been what like 2 years ago?


I'll be all about running that thing once I get all the bugs worked out and I'm sure its not going to tear itself apart like it did to me this last time. I think its been almost that long since I drove the car more than 5mins at a time <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

I'm running 3" pipe on mine w/ an X-pipe and bullets . There are pics in my sig .

FWIW - I did gain , coming from LT's/3"Y/4"spintech Mufflex . Its only marginally louder than that . The sound of the X and bullets together is sweet .

My setup on my 93 T/A:

Hooker LT's, 1 3/4" primaries
Custom made 2.5" y-pipe in to a single 3" intermediate
Cutout right before the rear axle
A Slowmaster muffler that rarley gets used
No cats

With the Hot Cam this thing it SCREAMS at WOT and sounds GREAT at idle. Just about as close to an open exhaust as you can get without actually doing so IMO.
