Not being big on medication, can someone tell me what you guys are suggesting to me? I will pass this on to my doc, to see if this is something he wants to put us on. Right now, we're taking Naproxinsodium and hmmm I forgot the name, it's a muscle relaxer, very small yellow round pills.
I take SOMA for my back on occassion. It is a muscle relaxer, however, anything over 250mg would make you very drowsy going onto to next AM. My doc gives me both 250 and 350. I have since stopped taking the 350 and only the 250 on occassion because it is very addicting. Hydrocodone is a strong pain reliever.
im guessing it should be additional...but i think this is another one for Brian
after removing charcoals was +10whp/+7lb-tq from baseline
after 2nd cat delete/x-pipe was another +5whp/+12lb-tq
total of +15whp/+19lb-tq from baseline
FWIW, my C63 gained almost +6WHP / +14 lb-ft RWTQ on the dyno after my high-flow cats (in place of the oem stock 2ndary cats; the rest of the exhuast is stock) had been installed...slightly higher increase than what the X-pipe is showing. For both dyno's I've done at RENNtech, my charcoal filters had been removed. Not sure if all the gains can be solely attributed to the high-flow cats, but either way, my car dyno'd higher.
Everyone thinks this product is no big deal and easy to make. I don't know anything about GT Pro, but I do have welding and fabrication experience and people don't understand the time it takes to hand make something like this. The time it takes for welding a perfect X (without a single leak) out of hollow stainless steel takes time, making sure it's made perfectly to bolt onto the car without a single flaw. The cost alone of tubed stainless is very expensive. For the record, I'm not going to buy it (sorry, I'm a cheap ******* and the stock HP and TQ are perfect for my track needs), but the gains sound decent.
There are many ways to go about this, our way, or the muffler shop chop/hack/weld, however everyone will have their opinions as to what is right for them, and I am no one to judge. I just feel that if you buy a nice car like a C63, it is a travesty to hack/chop your car at a muffler shop (no offence guys), but some will still do it, and that might be ok for them.
Basically boils down to this. I have only shown the LOWEST gains we have ever seen, NOT the highest, nor the biggest differential of lowest stock HP vs the highest Xpipe hp gain. I have posted the highest stock HP vs the lowest gain our Xpipe has seen, to ensure something for us... No matter what, the gains "actual" that will be attained are beyond our "claims", and EVERY, I mean EVERY customer of our product have been nothing but pleased, if there was a single person unhappy, I would gladly give them 100% money back, no questions asked. To this date, no one has taken me up on the offer..I do however have references of many happy customers willing to speak to anyone here about their experience with us and our products. Our product is MINIMALLY invasive, easy to install and a complete PROVEN product tested on the dyno and on the track.
Judge for yourselves, we stand behind what we do..We RACE/PROVE/DYNO our parts, no ands if's or buts. This is what we've done for the past 15 years, and we're not changing!
the car...i dont really know how to describe it...She sounds soooo much more refined at lower rpms ( < 4k), and hopefully i dont get destroyed for offering this comparison, but almost Italian-like.....above 4k She maintains the beast quality that we all love, slightly louder
the resonator was not removed so its not ridiculously loud
Can you remove the resonator if you want it louder and does this make the job more difficult?
I'm sorry but what are charcoal filters? Are they part of the 2nd cats or something?
Charcoal filters are black filters in the air boxes with the regular air filters; although they filter out some engine pollutants, they also make the airflow more restrictive.

Hi guys, we just finished Unbreakable1 's C63 dyno.
This is no way is advocating the removal of smog components, and is only meant for testing purposes.
Test conditions:
Baseline fully stock 91 Oct vs
GT PRO's new product called the "Single X" secondary cat delete for C63. (yes it is totally removable and your cats can be reinstalled after the test)
Baseline best (not lowest#, but HIGHEST # baseline was used)
Test was also performed with charcoal filter removed as well. (we saw 10hp 7tq on this mod alone)
We picked up 15RWHP and 19TQ, but the best part is that in the mid range we're picking up 25RWHP and 27tq, the mods also show a gain everywhere in the curve.
I hope you guys like it. We will be doing a formal release of the "Single X" and "Double XX" by this weeks end.
I have a hard time understanding $600 even for an x pipe.
I can buy all of the parts to make one, pre-bent for like less than $200 on amazon. It just involves some sectioning and welding.
The luxury tax on these cars is intense.
you are right brother it is absurd, I know mbh x pipe is a 3 inch diameter, was looking for a direct bolt on, the resonator delete x pipe on ebay looks okay anyone heard good things about Topspeed tho? I'll stop by some local shops and see what I can do... appreciate all the help guys!

That MBH x-pipe is OEM size not 3" and is meant for use in a stock exhaust system.
