    Boig Motorsport Announces Its New Quiet Pipes Side Pipe Kits!



    If you would like to mellow out your roadster a bit, and are particular about quality, then a set of all new QuietPipes baffled side-pipes may be just what you are looking for. If you don't want everyone within 150 feet to turn and look at you when you start your car at the gas station or coffee shop, then a set of all new QuietPipes baffled side-pipes may be just what you are looking for. If you would like to take your Roadster to church on Sundays, then a set of all new QuietPipes baffled side-pipes may be just what you are looking for. We think in many cases a Roadster with Quietpipes gets used and enjoyed more!


    Close-up of Quietpipes collector. Notice the high-quality welds and collector shape.


    Tight radius bends increase clearance to rear edge if body cut-out.



    Check out this video for a sound clip from Todd Buttrick's 392 Stroker. The dog even likes it.





    These pipes address the need for neighborhood friendly side-pipes. The outstanding feature is the baffled design with no packing to blow out. These side pipes will be as quiet after years of use as they are the day you installed them.

    The sound is sweet and powerful but never nasty. Have we made them too quiet? Maybe. 70mph cruise wind noise is a bigger issue. These pipes are made to order in USA with all new parts so you don't have to sacrifice your FFR loud pipes, or search for a donor set, or incur an outbound shipping cost.



    The collectors make a smooth transition and are a nice cosmetic improvement over the FFR collectors. Warning: once you see the smooth collectors, you can't un-see them! Also, check out the improved weld quality. The width of the welds at about 3/16" is about half that of typical Factory Five welds. The FFR collector is the cut-off pipe in the main photo. Our design also removes the FFR kink in the passenger side, meaning the 4 tubes, collector, and muffler section are all on the same axis. It just looks better. The pipe bend radius is smaller which provides more clearance where the sidepipe exits the body. The turnout has about 1" of extension for a more finished look, and angles down slightly towards the road.

    Plan for 2 - 3 weeks for delivery. Add a week for transit time if you are on the West Coast.



    Notes:
    - Photo shows collector with the smooth collector you will receive with your all-new QuietPipes.
    - Pipes come with Mk3 style two-hole mounting tab. Note in special instructions if you need a Mk2 style mounting arm.
    - If you install your pipe with gaskets, you must remove the unsupported center section "star" of the gasket before installation. If the center is not removed it will eventually blow out and is likely to get stuck in a baffle and cause unwanted sounds.
    - These pipes are fabricated in carbon steel only. Customer will need to paint (high heat black is our favorite) or have ceramic powder-coated locally.

    I have used these pipes on a 347 and a 427 MK4.Great sound, but you can have a conversation while cruising and actually hear the radio on a trip. Still sound great IMO when at idle or under acceleration.

    I ordered them last week and looking forward to a much quieter ride. Plan on having them ceramic coated locally in satin black.

    Any plans for 289 side pipes?
    FFR8551 289 FIA build in progress.

    We have jigs for 427 style sidepipes, that fit FFR supplied headers. These have been used on FEs, stroker motors, 351, 302, and 289 c.i. motors. We have not built anything yet for the 289 USRRC/FIA car yet. It's possible we can build a jig(fixture) from your present side pipes. Let's talk. 781-424-0882.

    Would these fit an FFR with catalytic converters?

    Yes TPM3, Quietpipes fit an FFR roadster with catcons. Quietpipes are an exact replacement size wise for FFR factory sidepipes.

    Very nice product - You may want to have a look at the 2 active threads on the Type 65 forum discussing sidepipes issues. Do you make a set of these sidepipes which fit the Gen 3 Type 65 coupe? I understand from others with experience that the Roadster sidepipes from FFR will hang too low and cant downwards if used on the Type 65.

    Thanks

    Are there any before and after dyno numbers? I am interested to see the HP and torque cost.

    Bill, thanks for the inquiry. We actually have a customer that has ordered headers and single exhaust tube sidepipes for his coyote engined Gen 3 Coupe. He wants a matched set of headers and sidepipes, custom fit to the coupe. Modifying the standard headers and/or sidepipes does not appear to be cost effective. We expect to have them completed after about 2 weeks. We are building production fixtures for future orders.

    Unfortunately Avalanche325, no dyno numbers. Not for not trying! The dyno shop first had computer problems, then he felt he had a problem related to the side pipes! And this dyno shop did work for FFR. After that a guy offered a bucket of money for my car (FE engined roadster) and I sold it.

    General consensus is the pipes cost 3-5% power. This is due to them being a baffled design, not straight thru like a glass pack.
