MRT, the engineered performance shop based in Plymouth, Michigan, introduces the newest edition to their premium exhaust lineup: the Street Race H Pipe for Jeep’s Wrangler Rubicon 392 .
“The stock 392 exhaust system is cool but not cool enough for the big HEMI V8 engine under the hood. MRT’s Street Race H Pipe is a real simple, good modification to wake up your Wrangler 392 just a little bit more than stock. Have a little bit more fun with it. Be tough when you want to be tough and you’re still a button push away from being quiet and conservative…This is the sound that matches Jeep. Just a ton of fun.”, stated MRT CEO, Scott Hoag.
Sound Engineering
Team MRT refined the factory exhaust with a mid-pipe section that replaces the stock X pipe and resonators with a more traditional H pipe so you get a deep full sound similar to old school muscle cars. Stock exhaust valves are retained so you have a similar sound at idle and start up. The MRT H pipe change is most noticeable in the performance mode of the exhaust giving you full sound at wide open throttle with a nice hum at steady state driving. This performance modification is extremely easy to do, retains all factory emissions components and is of high quality.
The MRT Street Race H pipe is a must have mod for your Jeep so you Hear the Difference, Feel the Performance and Get Noticed with every Wrangler off-road experience and driving adventure. Order your Rubicon Street Race H Pipe Here – Shopmrt.com
