just installed LTH!!!
Hi guys ,I have a 2007 CLS63 and just had LTH installed with catless midpipes.I currently have an XPIPE in place of where the resonator use to be and the sound is obnoxiously loud.Also notice a loss of low end torque.Heard that the best set up is to put the XPIPE where the cats were and put the resonator back in. I have another problem is that i can't find where I put my stock resonator.Hoping you guys can help me out by giving me advice on what my options are as in alternative resonator,etc...
Thought headers were suppose to give some decent gains, but disappointed so far. If anyone has a resonator for sale ,please let me know.Thanks a lot!!

Not to reiterate bad news but if you look at dyno charts of LTH you'll see most lose a little up front. With N/A motors you'll want a little backpressure. W/ superchargers/turbos you'll want more of a straight pipe setup.


What x-pipe brand did you go w/??

The Xpipe I have is Magnaflow. Spoke to a few shops and they also said that I loss alot of backpressure due to the larger headers.also putting resonator back in will also give it some back pressure and tame it some.
So I'm looking at a resonator with A built in Xpipe and that's probably gonna be done next. Has anyone ever try this?Have a custom dyno tune coming soon and hope to get the exhaust tone dialed in perfect prior. Thanks for all your info

Yep. Went with RT 300 cell HF Cats. Gonna install with them with my current Xpipe setup to see how it sounds. And if its still loud ,putting the resonator back in and moving the Xpipe closer up front. Thanks bro .
