Im planing on installing some headers and making my GTA dual exhaust, i have gone to the Flowmaster website and im unsure wich to get. i want Performance most of all and aggresive sound. i was palning on geting the 40series but dont know wich (delta, etc...) any suggestions.

It really depends how you are going to fab your duals up.. So.... what's the plan?

im trying to go with 3in tubing but depends on how much it cost

But you live in san diego will you pass smog that way i would go with which ever 40 series flowmaster also tell how much you spend at the end for i could do that

yes ill pass the smog as long as i have the state legal hedders which are the ones with the air tubes and as long as i have the cats too.

the super 44's will give you most agressive sound

I guess this isn't a daily driver? A setup like that would be ok for the track, I assume you will be dumping before the axle? Would be very hard to do, as others have demonstrated, and keep much ground clearance. The best solution I've seen ground clearance wise is with shorties and running both pipes down the passanger side.. Anyway with a good enough custom exhaust shop almost anything is possible.. Still I'd personally shy away from trying a street legal dual exhaust system on one of these cars if ground clearance is and concern..

Here's a good link for you, this guy did just what you're talking about, think he spent a small fortune on it as well, and still doesn't have the best ground clearance.. but it IS possible.. https://www.thirdgen.org/forums/exha...ve-3-true.html

Do you have the stock headers or which ones do you have i am planning to do that but not a dual exhaust and i live Oceanside

if clearance will be too much of an issue ill just go with smaller tubing... is not a daily driver jsut driv eit about 3 or 4 times a week so ill see whats best

well im palning on buying either some form Dyno Dons or the Hooker 2055HKR im still undecided on that

You should go for dyno dons i am saving up for his headers i have heard good things about his headers

Do u know if his have the 1 3/4 tube size???

regular 40s are the loudest flow they make they have a really deep drone to them and are loud under throttle they are your best bang for your buck if you have shortys you wont be able to run three inch tubing because the way the driver side header is built it will make it to were if you go down a hill you will scrape. i have 2.5 inch and everytime i go over a bump im out of my seat waitin for it to go bang.

your car didn't have the option of dual cats. you won't pass unless the smog tech doesn't check his books, which he most likely will if you show up with headers and a custom exhaust. not only that, to remain smog legal the cats have to be positioned in the stock location, which would be underneath the passenger seat. however you might get lucky. i know i had a hard time getting mine to pass, and mine was originally optioned for 2 cats, even though the tech said it wasn't, after checking his books he found it was optioned for dual cats, but had to be 2.25" pipe and 18"s long. even though it was 2.5" pipe and 16" long he just eye-balled it, and it passed.

if you do go with dual exhaust, do yourself a favor and get 2.25" or 2.5" exhaust, dual 2.5" is more than enough to support 500HP.

You should pm him he will tem you what size here are the pics he send me
