Louder? Heck, you cannot hear the Kicker sub-woofer now unless the back seats are down! Good grief! It only has a resonator after the catalytic convertor now - and the turbo needs 'some' downstream restriction to work. Now, change to a supercharger....

My wife's dad and brothers have a service shop... they want to put her new '05 orange blast on the lift now to see what was left disconnected... they are adequately loud 'as is'. I must be getting old... I can't believe I said that - and after all of the Ansa exhausts I put on my Alfa's... they sounded great, albeit not for long. Gotta admit, the OEM MOPAR lasts... my 90 Shadow ES turbo, which I just sold in September, still has the original exhaust... and clutch. I wonder if the SRT-4 will still be as functional in 14+ years??

Turbos do not need any downstream restrictions to work, they are their own backpressure and do not require it from anywhere else. Only normally aspirated engines need such a restriction to create backpressure to help the engine to accelerate quicker and achieve maximum performance.

 

was just gonna say that. no restiction is optimal

 

i have the mopar.borla exhausts on my srt-4 and it sounds throaty and deep as hell. i love downshifting and hearing the backfires.

 

I HAVE A 3" ALL THE WAY BACK WITH JUST A HIGH FLOW CAT. ITS PRETTY LOUD.

 

i got single turboback exhaust with d/p and racepipe... sounds mean....

 

That's exactly why I take my foot off the gas on steep downhills!!!!!

 

turbos are optimum at no back pressure?thats sweet...could have duals and not have to worry botu backpressure

 

That's right, turbos are their own backpressure.
