magnaflow exhaust on turbo set up
 

i searched through hmt few threads about mangnaflow mufflers, just seeing is any current members are still running there. i got the 12280 in the mail today for my ef. it has a 2.5 input and dual 2 out puts. its basically going to be set up sideways like the original si exhaust. my turbo down pipe is 2.5" and i am going to weld that to a 6" long 2.5 flex section that i got, then weld in my 2.5" magnaflow hi-flow cat. i am debating if i want to try to find a 2.5" resonator. i guess i ll try the exhaust system out firs without the resonator, then if tis too loud, ill add one in. i also need to find 2 exhaust tips that will slip onve the 2" piping that arent too big, kinda like the hks ef exhaust. not sure how bid the i.d. on the 03 acura tl exhaust tips are, but those would be perfect.

heres the muffler

Re: magnaflow exhaust on turbo set up
 

intresting, is carsound a magnaflow company, i could of swarn it came in a magnaflow box when i brought it

Re: magnaflow exhaust on turbo set up
 

I have 2.5 with nothing but a $20 thrush turbo muffler on it. nice and quiet but still sounds nice, I've heard those magnaflow mufflers on turbo cars, they are pretty noisy but not horrible. def. has a nice throaty sound to it.

Re: magnaflow exhaust on turbo set up
 

they do come in magnaflow boxes

Re: magnaflow exhaust on turbo set up
 

well, i will see how long this one holds up.

ya or nay on the resanator

Re: magnaflow exhaust on turbo set up
 

Gut the cat, you won't regret it. You might not need to where you are, but in VA you need to have a physical cat, everyone just guts them.

Re: magnaflow exhaust on turbo set up
 

if i wanted to i could just run a straight pipe. but i really wanted to have some type of cat on there

Re: magnaflow exhaust on turbo set up
 

Just run your afr's a hair richer once you hit a higher load (or on speed density systems once you start hitting a decent boost level, maybe above 4-5 psi). It won't make as much peak power, but it'll save the cat by running cooler egt's. If you try and keep your boost afr's near 11:3 at the leanest point (above the 4-5psi mark of course) you should be ok.
As for the muffler, I had the single 2.5" inlet/outlet on my old turbo'd b16 hatch. Sounded great, very quiet (a little too quiet for me, I like to cause a ruckus >:D), nice deep tone and no rasp. I think you'll like it.

Re: magnaflow exhaust on turbo set up
 

thanks for the info, anyone have sugestions on the resanator?

Re: magnaflow exhaust on turbo set up
 

I love my magnaflow muffler. when I put the turbo on there wasn't any buzzing like every other honda with a muffler. even without the turbo it sounded good except when I got on it real hard. The best sounding exhaust out there for a honda I think. The best part about it it when you are just cruzing it doesn't drone inside the cabin. nice and quiet.

Re: magnaflow exhaust on turbo set up
 

yeah, i think i made a good choice. now i just gotta find someone to weld it all together who isent going to rape me. i might try it myseld with my cousins flux core goodness

Re: magnaflow exhaust on turbo set up
 

you aren't that far from hotrex or coreyr

Re: magnaflow exhaust on turbo set up
 

Come to New England Dragway 08 season I will be racing my turbo d16y7 hatch for the first time.

Re: magnaflow exhaust on turbo set up
 

you won't need a resonator unless you're going for super sleeper status. And don't bother with buying a resonator in specific if you do, just use a cherrybomb turbo straight through thing--they are cheap as ---- and sound sweet

Re: magnaflow exhaust on turbo set up
 

when i am done i want it set up like this http://www.we-todd-did-racing.com/we...ZkMzF5NTQx.jpg

Re: magnaflow exhaust on turbo set up
 

Cats overheat and die from overly rich conditions, not from running lean.

Re: magnaflow exhaust on turbo set up
 

And cat's usually melt solid from lean conditions. I should know, I have quite a few collecting in my garage that are melted solid from running mid 12's to 13's afr's under high boost. And if overly rich conditions does what you say to a cat, why do most stock boosted cars run down to the 10's afr's under full boost? My Evo was a case in point when I first bought it, 19psi with a 10.4 afr. Not to mention my Wrx that had 3 cats and still ran a mid 10's to low 11's afr.

Re: magnaflow exhaust on turbo set up
 

no cats, magnaflow dual 2.5in outlet w/ 3in inlet. thats what i want too.

Re: magnaflow exhaust on turbo set up
 

No cat is the way, but if you really have to have one for inspection/emissions purposes I'd suggest making a section of the exhaust a "test pipe" section so you can swap the cat in and out for inspection time.

Re: magnaflow exhaust on turbo set up
 

stock cats burn up when a/f's are too rich(cats burn unburnt fuel more fuel more heat), aftermarket cats burn up because they are ----.

Re: magnaflow exhaust on turbo set up
 

No cat, cherrybomb for a resonator, cheap turbo muffler. Done.
