JDL front pipe/Perrin 3" Resonated vs Nameless downpipe/axleback?

[Jesse@JDLAutodesign]

Regarding the 3" stuff...Fitment is much tighter but another thing to note that really effect fitment is the motor mounts. We have our shop car here that we test fit parts off of all the time, The car has less than 4k miles on it (don't ask lol). Anyways we did a recent install of a 3" overpipe/frontpipe combo on a local customers car and after trying many different things could not get clearance off the subframe. The same pipe fit the shop car with plenty of clearance to spare. We took measurements off both cars and realized that the customers car (with 80k+ miles, 30k of them with forced induction) the motor sagged/drooped slightly over 3/8" inch. We upgraded the car to cusco mounts and the pipe had clearance everywhere.

Thanks Jesse@JDLAutodesign , so would the 2.5" overpipe/frontpipe not run into any clearance issues or require new mounts?

I currently have a DC sports catback. I want to pair it with the jdl el and the ultra quiet front pipe but im afraid that it'll still be too loud.

Sorry for the delay in the video. i actually contacted jdl today and bought the resonater. i got the front pipe with just a cat and i have some rasp i want to get rid of but it still sounds amazing.

Are you still running this exhaust configuration? I simply breath on the gas pedal and it is too loud. I am running all 3" piping, JDL overpipe, UQFP and their 3" muffler. I'm wondering if their muffler is the issue. Just too loud! Solution ideas anyone?

"Review "installation" - After leaving the shop we noticed that the OP was hitting the sub frame. After doing some adjustments we were unable to resolve the issue. I drove the car through the weekend until Monday when I began an email chain with Ronnie @ JDL. After providing a few Pictures and adjusting what i could from the engine bay ( I didn't have a way to lift the car) i set up a day to go back to my installer. Using the tips from JDL we were able to resolve the issue. The V-Band from the OP/FP was hitting the sub frame. To resolve the issue we hand tightened the bolts on the OP/Header and the V band. We then pushed the OP upwards and tightened up the bolts to finish the install. This gave the V band about 1/2 inch from the sub frame to resolve the issue.

Support - After a few emails JDL picked up the phone and gave me a call. We went over the install process and pictures which they then used to provide the install tip to resolve the issue.

Over all i am fully satisfied with the Quality of parts and Support from JDL. The car sounds amazing. No rasp or drone at any rpm. If you are cruising at any speed the car is fairly quiet however the car will get loud if you accelerate but it's never to the point where it is uncomfortable. I was able to have a conversation with a really soft spoken 11 year old girl while driving around town. Video Plox? All i have to make a video is my camera phone so it may not be the best quality. I am upgrading to the Note 5 so maybe i can try with that. Now i have the problem of the car sounding awesome but still being slow cause i'm still NA."

I'm still running this config and absolutely love it. Make sure you get your resonators to remove rasp/drone. I have a few friends with a track pipe and those things are loud!!!!
