3" exhaust questions

[smudge]

So, the 3" catback has been ordered

Header will either be custom or a JDL UEL with a 3" collector

Overpipe and frontpipe will most likely be custom made seeing as Nameless don't want to get back to my emails, website inquiries or PM's on here...shame

I'm in the same boat as @smudge running the Sprintex 335 supercharger.
I want to get the most out of my setup so I am considering running a full 3" exhaust. I don't mind loud, but I don't want my ears to bleed...

The two setup options I am considering:

2.5" setup
JDL catless UEL (for more low end power and subie rumble)
JDL 2.5" overpipe
JDL 2.5" catted/resonated frontpipe
2.5" ARK DT-S exhaust or 2.5" JDL D2 exhaust

3" setup
JDL catless UEL (for more low end power and subie rumble)
JDL 3" overpipe
JDL 3" catted/resonated frontpipe
3" JDL D2 exhaust

I would think the JDL exhaust is much lighter than the ARK, but I can't find a lot of information of users having experience with the JDL exhaust. I found they have different tip options and are running a Magnaflow resonator. JDL's quality is top notch and it might be best to run their full setup. Just not sure if it would refine the sound better with the ARK DT-S and avoid DRONE.



JDL exhaust has an option of JDL Tips or Standard Double Wall Tips, just not sure the difference and diameter, etc.
Looks like they might have a slash tip option which I would definitely go with if I choose their exhaust. Not sure if the JDL will DRONE.

I used rubber grommets I made from scrap and wedged in between the engine and the frame when aligning my three inch overpipe. I don't get rattles or anything at idle or down shifts. 1 tip is to leave the exhaust bracket by the transmission loose when aligning the over pipe. Have someone up front checking clearance as you raise or lower the exhaust from the transmission exhaust hanger bracket.

Fullblown Motorsports was kind enough to give me a flex pipe on my exhaust just passed the other pipe. With a tiny bit of force I was able to align everything perfectly.

Fullblown Motorsports doesn't advertise publicly but they do offer a over pipe all the way to axle back that is entirely 3 inch with v bands cheaper than nameless in the other competitors. I had 0 fitment issues...

You will not find this exhaust with over pipe and front pipe on the website you need to call them directly.

Anyone have any input on the three inch Xforce exhaust?

Seems like a bargain with a decent sound.

Decided on full 3" setup from JDL

JDL catless UEL (for more low end power and subie rumble)
JDL 3" overpipe
JDL 3" catted/resonated frontpipe
3" JDL D2 exhaust

Bargain for a 3" system? Those 2 things shouldn't go together...I'd be worried about quality

[Summerwolf]

Its Xforce....so their reputation is pretty established. I just don't think its popular or well known here in the states. They are a huge exhaust company in Australia.

Just don't know of anyone running it, and there are only a few threads here about it. Overall consensus seems extremely positive.

Nice! You should take some vids so we can hear what a full 3" JDL setup sounds like.

I'll get some videos up as soon as I can.
Full 3" JDL, Sprintex Supercharged!

I'm booked in to have a custom UEL manifold (2" primaries to a 3" collector in a 4-1 design) with a 3" overpipe and frontpipe on 9th November. Can't wait to have it all finished so I can get the map done!

I assume you are going this route to eliminate more bottleneck

The JDL UEL is:
1.75″ Primary Runners
Low Angle Merge Collector with 2.5″ Outlet

Only header I know that's 3" is Nameless.

I'd be surprised if a good 2.5" system is much of a bottleneck. I'm not really sure even today why I went 3" - even pondering a swap of the whole setup to get the car quieter.

So is it an issue running the full 3" JDL system, as their header is not a 3"

Bigger bore just allows for more flow. Bigger the better
