Flowmaster introduces its new Slimline sidepipe style mufflers. Intended for Shelby Cobra sidepipe applications, these Laminar Flow technology mufflers can be used in other applications and feature a raw 304S stainless steel case with no logos for a cleaner appearance. The inlet and outlet diameter is 3.50" with a 4.50" body and 24.00" or 30.00" long case. These mufflers offer a quieter alternative to the glasspack style mufflers that are traditionally used in these applications, plus the Cool Shell Technology helps prevent the outside of the muffler case from seeing the extreme temperatures associated with sidepipe applications. The Slimline mufflers are backed by Flowmaster's Lifetime Limited Warranty. #Corvette #ShelbyCobra #Sidepipes

not bad at all

[@chadminor2360]

just went to the website and did a search. I don't see this product. is it just a muffler that you add to a hooker style sidemount headers or do you offer a header/muffler setup?

[@FlowmasterInc]

+chad thomas You can find the product page here: bit.ly/20YtAnZ The Flowmaster Slimline Sidepipe style muffler is a universal style muffler and does not come with headers. If you have any other questions, don't hesitate to call us at 707-544-4761.

Any idea of the sound level in dB, for a Cobra build with 5.0L Coyote engine?

[@FlowmasterInc]

No, due to a number of factors we do not perform dB testing. I can tell you they will be very aggressive but it will sound so sweet! - Jason @ Flowmaster

[@nicholass8122]

is it possible to put this setup on a 99 Tahoe with a 5.7 vortec 350

[@FlowmasterInc]

Hi, As these mufflers are designed for universal application it may be possible to have a similar setup on your Tahoe. However, it would require extensive fabrication. Additionally, Flowmaster does not recommend replacing factory single inlet exhaust systems with a “true dual” system on computer controlled vehicles, as the computers in most late model vehicles may not be able to compensate with the fuel needed when increasing the exhaust flow. If you have any additional questions, or if you would like a personalized product recommendation, feel free to give us a call at 707-544-4761. -Team Flowmaster
