either let go or unstick your shift key, or turn caps lock off


two mufflers wont fit under the middle of the car if you still want decent ground clearance. one will, two wont. youve got a lot of options, its really a matter of what you want to spend. i have a 2-1-2 using a flowmaster 80 series and i think it sounds pretty good. alot of people run true duals with mufflers in the rear, alot run a Y pipe with a muffler toward the middle of the car. i think flowmaster sounds the best hands down, but i know they dont flow particularly well. im not too modified, so im not in need of a high price high flow muffler, i did it for the sound.

Talking Agree with J-Rob, also....

if, as he mentions, flow IS important to you - have you
asked Spintech what the flow rates are for the mufflers
you're interested in? They didn't offer that info on
their site. Whether you like 'em or not, you might compare
their rates with someone like Dynomax who does post flow
rates.

i had my eyes on some called xtrem flow.which had a flow chart and marked better then flow and borla , dynomax...then i emailed spintech and they emialed back saying that spintech flow great....have you seen the inteior design on spintech..it looks like curls, and like they say never say never i bet i can fiquer a way to place it under the carraige....if you know bout exhaust system.the new cars new backpressure. and the only thing for back pressure are the cat ( minus the 3rd cat and res.) so if i place the muffler under the car i would get better backpressure......more hp......

sooooo.... youre saying that spintechs flow great because spintech told you that spintechs flow great but couldnt give you any flow numbers? thats a little sketchy. get some numbers, dont believe "we are great". curls also wouldnt be good for flow. hooker sells straight through mufflers, thats good flow.

the placement really isnt up for arguement, two mufflers WILL NOT fit in the exhaust channel in the middle of the car. its just not happening. i tried it and it doesnt give you much ground clearance and doesnt particularly look great. DOES NOT WORK.

is that supposed to say "new cars need backpressure"? all cars need some backpressure at low rpm, new or old. mufflers, X pipes and H pipes and generic exhaust bends can create backpressure, this isnt exclusive to cats. also, placing the mufflers midway wont create more backpressure than putting them past the rear end.

Talking I have nothing bad to say...

about Spintech....I simply ask the question - what are
their CFM flow rates? The statement that "they flow
great"....tells you or me exactly nothing. Yes, your
primary cats are producing back pressure.....but so
CAN mufflers...so, until you get numbers concerning
their CFM capabilities - you won't know whether they're
contributing to your exhaust system's overall total
back pressure profile or not.

Make them disclose their mufflers CFM flow rates.....
they SHOULD be HAPPY to give them to you....

Have 2 40 series Flowmaster mufflers on my car where the 3rd cat is. Never had any clearance issues. and they wont hang down low as most people think as long as they're welded together to keep them in place.





I have this set up on both my 1997 4.6 Thunderbird and my 1993 5.0 Mercury Cougar. Both systems have 2.5 inch pipes running through.


Hope that helps!!!

Cheers

but you also arent lowered. i had the same exact setup on my car, and even before i lowered it i would scrape over some bumps, pulling into driveways, some speedbumps, etc.

you are going to lose a couple inches of ground clearance no matter what, and its in the worst possible place. it also doesnt look very good to see the two mufflers hanging down, IMHO

just my $.02 though

here, you can see what it looks like. i can assure you the mufflers were placed as close to the body of the car as possible.





another shot, cant see as well because its a crappy pic... oh well

Appreciate the info......

I'm still a firm believer that the mufflers should be up front. I hate the mufflers being all the way in the back. And having the mufflers hanging down a little bit gives that muscle car appeal

i agree with having them up front, its just not possible on these cars if you want ture duals. with a Y pipe you can tuck one nicely up into the channel and not sacrifice too much clearance, but two just wont fit up and in.

for me, the hanging mufflers gave me a "hey that looks like crap" appeal.

Matt,

True duals are possible with a 2 in/2 out muffler. It would be installed, tucked up where the 3rd cat, resonator is. I was looking into these myself. You can get one from Bassani, Magnaflow, etc.

i never considered that true dual though, but i guess that depends on the muffler construction. that is a good point though, i totally forgot about that option.
