Quad Exhaust and Pipes

94Lsedan · 07-09-08, 01:56 AM

I may be going down to a performance muffler shop soon. I wanted to put some nice muffler tips on, but I may go ahead with a quad exhaust setup for the Legend. I always wanted the rear to have 4 pipes sticking out kinda like L3GNDKNG's sig.

Would this be a bad idea for the Legend or will it work with no problems? I want to know what size pipes I should go with and how I should setup the pipes, that way I will see what the guys at the shop say. I plan on using two Stromung Dual Exhaust Mufflers to complete the Quad setup. Good idea or bad idea?

i think it will be good and will be waiting to see this if u actually do go through with this

DandDEE · 07-09-08, 02:03 AM

i think blkonblkcoupe has this setup if im not mistaken

94Lsedan · 07-09-08, 02:06 AM

Well what about the O2 sensors. Aren't there a couple in the exhaust pipes?

DandDEE · 07-09-08, 02:07 AM

hmm i dont think so only on the headers

blkonblkcpe's Setup is a single. He had a photoshopped picture of a dual exhaust setup, with two twin tipped mufflers (AKA "quad").

The only O2 senors on a G2 are in the headers, the rest is all just tubing.

On my dual setup, we used a merger piece where the A-pipe (or Y-pipe) originally was, for balancing purposes. (Read: pulses and all that) The piping was 1.75" from headers back to two "mufflers" at the end, and by that, I mean straight-piped resonators with shiny tips. (See: eBay $20 muffler)

We had to cut the spare tire area to run the passenger piping to the other side of the car, as the axle was sorta in the way.

I hope that answers a few questions.

pics please

Lol. Well, there's nothing to see right now. 90% of it is wrapped up ona shop floor while we build the tranny and motor and put it in. Remind me again when it's running? :p

DandDEE · 07-09-08, 03:06 AM

alright will do

94Lsedan · 07-10-08, 12:59 AM

I'm just worried about engine damage, backfire, overfueling, and long term effects. Is there anything I should look out for?

The Crowing · 07-10-08, 01:42 AM

I haven't had one issue... dunno why you think all that would be occuring?

95LegendGS · 07-10-08, 04:19 AM

I'm having a prototype dual exhaust being made currently for my car. It features a 3 inch pipe to 2 2.25 inch pipes and 3 mufflers. So far it looks promising and looks awesome on the car. But mine are only 2 tips total not 4.

maybe some of the OG's can remember who owned this car

The Crowing · 07-10-08, 12:32 PM

Thats very nicely done.

Dammit, now I'm all intrigued by this again. I want to run a true dual setup, each bank having it's own seperate piping. Back when we did our project, I was convinced I needed a union for pulse balance. Is this absolutely true?

*sam o nela* · 07-10-08, 01:39 PM

While I admit that I am not too knowledgeable on the subject, I have always heard that for a true dual setup, a cross over (either X pipe or H pipe) is needed to balance and smooth out the exhaust flow:

X Marks the Horsepower Spot--MagnaFlow Tru-X Crossover Pipes - SummitRacing.com

True dual exhaust

I believe Ford might be the only company nowadays that still does this, and you can find many debates on mustang forums in X vs H pipe....dont know how effective it'd be on a C32 (believe you'd need two small cats too), but just thought Id throw it out there
