Dual Exhausts

[JUICED4G64]

I am looking at putting dual exhausts on the 8G. I know that it will decrease performance, but I like the look. So how do I go about doing this?

its does look that bad, please dont do a skinny tip like what i saw this guy have the other day i was dual and the cut job on the second side was horrible and the tips were like 1" it was gross

this is my dads galant what he did was make something like a u shape out of the exhaust pipe behind the exhausted its technically a 90 degree bent pipe attached to the original

[Gladiator]

doesn't it theoretically hinder the performance of the vehicle because of more resistance to the exhaust that isn't designed by the factory?

[RAZ_76]

I personally think it's a waste of money and it's rice to put dual Exhaust on a 4cylinder car, even if you have turbo. If you do it, this is what you will hear a lot: V6? No! 4cyl.Then this behind your back, what an idiot...:lol:

Tell your dad to either bring the right tail pipe up or left down. Looks uneven.

what about putting this on a V6?

[RAZ_76]

This picture I posted is a V6 G. So yes most V6 cars come with dual.

but will it sound ricey on our v6's?

[RAZ_76]

No! V6 does not sound rice! if you go with like Greddy evo II or greddy Ti-c, it will sound good.

i was thinking magnaflow

[G-spot]

magnaflow is ok too

[RAZ_76]

Magnaflow is good too.

[RAZ_76]

Get out of my head..:lol:

[seth98esT]

Just dont weld the second exhaust to the exhaust, just put it on hangers. No performance decrease, all the looks of duel exhaust :P

[fliegendaffe]

Get out of my head..:lol:

LOL

i have a single exhaust right now with the magnaflow race series 14851 i think it is

[wright06jhs]

this is the kinda exhaust im getting! cant wait...

[6G72gearhead]

There really isnt any performance gains to dual exhaust in anything. Hell I see alot of build turbocharged LSx motors running single's. Nothing wrong with a single, but if you absolutly cant do without the look, run a single back before the muffler then Y it off, its not really going to be dual exhaust, it will still give you that look though.

[Kalamidad]

i have a y-pipe sitting at home, i got it from another member a few years back. just pay shipping and it's yours.

[bmaddock]

Ya at the moment I'm teetering between getting dual exhausts. I love the look but I'm afraid its a little close to rice-looking. I dunno, if i find some cheap mufflers to dual with a y-pipe than i might do it.

Does anyone know how much hp is lost by adding a second exhaust?
I have the V6 model if that makes any difference

Ya i read before i posted and i got that it doesnt sound ricey with a V6 but i read somewhere in there it might hinder performance, so i was wondering how much as in a number??

[fatal1]

couldnt tell you since theres no dyno sheet out tehre im aware of and you cant really guesstimate it either but it would still be in your best interest not to do it since it wasnt designed for it... unless of course you plan on spending the money to really have it done correctly

[fliegendaffe]

lose hp? i doubt that since there is less restriction on the flow

[Ruslik]

For raz every car is rice except his

[RAZ_76]

Shut up nooblet!! whats rice on my car??? If you gonna open your big fat mouth than have prove to back it up.

[Serstylz2]

that was meee

[Danger DANJ]

Unless you have a V6 and run separate piping for each bank all the way back, I wouldn't bother.

[BIGMONEYDAY]

I also have a V6 with a dual canister mufflers set-up. I used a Ractive canister style with 4.5 inch round tips. All the members in the ATL area and also a few in the Savanah area have seen and heard it. The muffler has a nice low tone, and not the raspy ricer sound. However the shop that originally mounted this system didn't do the best job in the world, it was ok for the price at that time. They put more of a "T" in the piping, by branching the 2nd side off the original exhaust, rather than mounting a "Y" in the pipe further back. So now 90% of the flow comes from the original side and 10% from the 2nd. Also they are slightly uneven and hang too low. Every time I come off a decline or up an incline, they scrape a little and my car isn't even lowered. I plan on having it redone by a different shop,when it's closer to the time for me to lower and install my kit. But this time I'll be using a Y- pipe, and 2 regular style mufflers with smaller, oval tips for added ground clearance. This is the tip I'll be using for version 2.0:

funny thread! lol

[JUICED4G64]

It looks great when you get a body kit as long as the hole on the right side of the rear bumper is cut correctly and looks flush. Any suggestions on a kit I should get for dual exhausts?

[RAZ_76]

Any body kit, really! I mean they don't make one for a Galant with 2 exhaust openings so you will have to make one yourself, so get whatever you like.

[JUICED4G64]

No, I meant what exhaust kit should I get? I was looking at GReddy.

[criz067]

I am not thinking about getting dual exhaust but i was just wondering, technically, why it would reduce performance to switch to it???

[RAZ_76]

Greddy is good!

[RAZ_76]

The difference would be unnoticeable if you just do 2 mufflers unless u run FI .... basically. You need true dual, you would get arguable more hp because of the exhaust goes straight to the muffler while the stock exhaust (y-pipe), the pressure would get built in the middle before being splitted on the rear/muffler again , hence less smoother flow.....

So it just comes down to preference .

[fliegendaffe]

i don't see why it would reduce performance

[fliegendaffe]

if you put a "Y" pipe on there, there will be no build up of pressure, no loss of performance, and no loss of smooth flow.

true dual will obviously be your best dual exhaust, but doing a dual with a "Y" or "X" pipe, won't hamper anything.

[dknight3]

the only non-ricer exhaust is stock. (besides fi'd cars)

and i doubt the performance difference will be noticeable.

unless you do what that one guy said and run a separate exhaust from the banks or w/e.

[criz067]

It seems that there may be more power from true dual b/c of better flow but since the backpressure has decreased the low end torque may be lower but high end would be higher.

[6G72gearhead]

No, a larger diameter pipe has more capacity to carry volume, again, I've seen turbo big block cars run in upwards of 5" single exhaust. When they make 2500 hp off a single, I dont see any reason for duals, aside from looks.

[Reelax]

super rice LS1 exhaust:

[RAZ_76]

^^^^Thats nice rice because it's unique :lol:

[6G72gearhead]

Thats alot different then what the op has in mind.

[WarmAndSCSI]

Okay, let's end this now. No, increasing flow will never decrease top end power unless you fuck up the scavenging effect of your headers.

Having two pipes after a certain point where there used to be 1 pipe will only increase top-end power (unless the combined flow of the two pipes is less than the original).

[Reelax]

Thats alot different then what the op has in mind.

no kidding... but it still is a dual Y setup w/ dual mufflers, like what we are talking about. piping is 2.75" downpipe to resonator section then split to 2.5" dual sections w/ turbine mufflers (no internal packing) then to cast aluminum dual tip section. power feels no different than when I was running straight pipe 2.75" to thermal race muffler w/ 5" tip single... the new setup is just way quieter. the biggest flow gains actually came from removing the precats on th CA spec, the main cat flows pretty well although it was removed by the downpipe also.

found a better pic of the piping:

http://i242.photobucket.com/albums/ff8/ooreelaxoo/underback1.jpg

notice how tight they kept the piping to the spare tire well and that Y piping goes above the rear cross member for ground clearance. piping was done by a race shop that builds headers and cost about $300 for install and custom fabrication.

[djflex167]

i love the exhaust on REELAX's Car its crazy hot and unique like RAZ said!

[6G72gearhead]

That piping looks amazing, you really dont fuck around do you.

[Reelax]

That piping looks amazing, you really dont fuck around do you.

well like I said, it was a race shop that specializes in making custom headers. it's all mandrel bent and very tight to the car... $300 for piping is expensive, but the job they did was excellent, especially the Y section that starts way before the rear crossmember (not visible in the pic) for flow. u can really see the difference compared to the other duals in this thread.

[99 galant]

that dual is sick in the center

reelax is that really yours?

[Reelax]

thanks. I wanted to do domething nobody else could copy easily. the tips and rear valence (cut then molded to rare JDM super vr4 rear lips and stock bumper) are discontinued and hence super rare (SLP 35th anniversary camaro SS limited edition)... to copy what I did would cost around $1300+ if u could even find the parts. it's sleeping in my garage right now.
