i have been thinking to trade my hooker cat back exhaust in very good condition, for a atr 3'' single shot!!!
Why would you do that? Your increasing from 5.5 " in to 3" of back pressure. Plus that ATR system is louder unless you like noise & the drone & the dual exhaust looks better.i have been thinking to trade my hooker cat back exhaust in very good condition, for a atr 3'' single shot!!!
Heck! just get an enema & they can bury in a shoe box !Bacause its 40 lbs lighter and will last FOREVER AND EVER UNTIL YOU DIE
BTW 9.74 through the pipe 25 PSI
The hooker dual has a lot more back pressure than a single shot with a nice straight through muffler, this was tested on a friends car at the crossover with both systems and the backpressure with the dual was about 10psi over, hope that helps.
Cruz this is what confuses me. Anything Kenne bell or ATR was crap & this has been known for years except for the newbies. Is the question about a race or streetcar. If its a race car we are talking about it should have zero back pressure as in a 3.5 or larger D/P with no muffler. Maybe I shouldn't respond to these entry level posts & save myself the embarrassment.I have a 3in system (single) and I CAN tell you, YES, they drone, and YES there LOUD!
its sitting in the back waiting ....... for what? I dunno.
mine has a 18in pitbull muffler,
I have a hooker system on my WE4 with dyno max turbos, quiet, no drone, no rattles, no looks from the cops!
Yeah Gary that's what I'm talking about !I believe that a single ATR 3" exhaust set-up is quicker than the standard Hooker cat-back exhaust.
I've been told this has been proven on both the track and a dyno.
I have read and been told that the 3" single shot is more efficient that two 2 1/2" pipes.
However, the single shot 3" ATR does have a serious drone and loudness problem.
Aesthetically I just can't get used to the looks of a single shot exhaust.
I would never run a single shot exhaust, I don't care how much power it develops & how much it makes a car go faster.
Nor would I ever even think of trading my Hooker cat-back for one, regardless of the condition of the ATR set-up.
Most of my comments are directed towards street use and not actual track use.
