    Megan Racing 2.5" Downpipe For R18 Owners (HF, LX, EX, EX-L trims)
    MSRP $195
    [​IMG]
    [​IMG]

    Megan Racing Stainless Steel Down-pipes are made of the same high-quality T-304 that is utilized in our Headers and Turbo Manifolds for extreme durability and resistance to corrosion and cracking. The missing component between any Header/Manifold and your Cat-Back system, these Down-pipes will complete the high-flow exhaust system desired for the performance of your vehicle. With a noticeable power gain throughout the rev-range and a polished finish, these are a perfect addition for any performance vehicle. Expect an increase in exhaust tone, due to freeing up the exhaust flow and the deletion of the catalytic converter. (NOTE: For off-road use only, not intended for use on public highways.)

    Key Features:
    • Significant power gains.
    • High quality, 100% T-304 Stainless Steel.
    • When necessary, Megan Racing uses stainless steel flex joints to help dampen the cat-back exhaust system from engine vibrations.
    • Bolt-on installation.
    • TIG-welded for strength and durability.
    • Straight-through design and bolt-on installation.
    • CNC-machined flanges for strong solid support and mandrel bent tubing.

    Header Design:
    This Skunk2 Alpha Series Race Header features a large 4 inch bellmouth design with 3 inch outlet is manufactured from high quality cast stainless steel for superior heat resistance and strength. This design enables maximum extraction of air flow and increased power. Heavy duty 1/2” thick flanges ensure secure and leak free attachments.

    So the full race and the skunk2 are catted, though will both pass california smog test? or is that something I should ask the company themselves also would they fit with a tsudo or an Greddyevo3 exhaust system since the piping on those are 70mm(2.76)

    This is next on my list for mods, probably be ordering later this week...
    Really want a 3" one so that narrows it down to the skunk 2, UR, and FR.
    Was going to go with skunk 2 but some users have been complaining about a whistling sound that sounds like a leak, which some cant even stand....

    How long have you had it? How many miles? If I recall, you haven't had it that long. I you could get 75-80% of the average going retail price right now.

    Situation sucks, btw. :( Sorry to hear.
