Supertrapp: Lives up to the claims

October 1, 2013

Super easy install on my 03 wide glide. Took about an hour. Great performance on basically stock 88TC. I've got a 42mm flatslide on there too. Installed all the discs and an optional open end cap. Quieter than my screamin eagle slip-ons, and much smoother. I can't say I love the 2-1 sound, because I don't for idling and low speed, but when I get on it the thing screams. Very smooth and quick acceleration right up to the limiter, which I don't think ive ever hit with the stock setup. The performance gain is worth the sound compromise for me.

I would recommend this item to a friend.

Supermeg

September 26, 2013

I found this item to be high quality,and simple to install.To my surprise the performance increase acquired with minor jetting adjustments has confirmed supertrapps claims for this exhaust. Thanks , for a great product.

Very pleased

September 25, 2013

The manufacturer replaced the front heat shield due to chrome flaking after less than 100 miles, and this took more than 2 weeks because they required pictures as proof, and I had to email them several times. Finally everything came together. The Supermeg 2 into 1 is quieter than expected with the end cap installed and 20 discs, but it still has a good deep note on my 2003 Fatboy. Several Harley riders commented how much they liked the looks and sound. After a not-so-good beginning, I am finally very pleased with the final results. Using the Vance & Hines Fuelpak and Arlen Ness Big Sucker stage 1 air kit. After describing my set-up, I was able to get the proper program numbers from Vance & Hines even before I received their Fuelpak. Runs great with a noticeable increase in power.

I would recommend this item to a friend.

Supermeg 2 into 1 supertrapp exhaust

March 11, 2013

I installed the supermeg on my 2006 Fatboy replacing the (Vance and Hines big shots, nice pipes a bit to loud around town and when you it on it hard) The supermeg sound is deep and not to load until you get on it hard and then you can here the roar. You can feel the difference between the two systems with the supermeg 2 into1 having better torque and throttle control. Easy to install just remember to get 2 new exhaust packing gaskets. Also nice fit and finish.

I would recommend this item to a friend.

Mellow sound and good performance

September 27, 2012

Excellent fit and finish. Adjustable sound and performance, you can't beat that. I went through 3 different exhausts, and wish I had got the Supertrapp in the first place. I'm very happy with the 2-1 Supermeg and Dennis Kirk for shipping it quickly.

Excellent Deal

June 29, 2012

Perfect fit, great sound (with end cap off), good torque improvement, and after 500 miles, NO discoloration! This is the 3rd set of pipes I've had since removing the stockers, and the only one I'm 100% happy with! Saved over $100 by ordering through Dennis Kirk.... You GuyZ Rock!!!

Great replacement for stock pipes

July 7, 2011

Installed this on a '05 FLHRS that already has an intake and Dynojet. The sound is much to quiet, almost like stock mufflers. I installed the open end and removed discs per the instructions and now I'm very happy with it. I ride 107 miles round trip to work everyday and the sound doesn't get grating, and I believe it wouldn't interfere with a stereo either. The seat of the pants power is noticeable too.

I would recommend this item to a friend.

Awesome Pipes

May 21, 2011

Replaced some lousy BUB Cross Dressers with this pipe. It was part of a 95" upgrade with Andrews 37 came and Mega Flo Ported heads. Doc Watson dynoed it and with 20 disks and open cap he got 110 hp and 108 tq from a 95" those are decent 103 numbers!!!! I love these pipes as they aren't too loud even with the open cap. Doc tuned it to the T on his dyno and he is one of the best. He recommended the pipes over the VH Pro Pipe and DD Fat Cat and I am ecstatic.

I would recommend this item to a friend.
