Anyway. Coming soon...

P.S. Just make sure it doesn't rattle like the old exhaust. I'm sure everyone heard us when we were in the backseat last time.
eee ahh eee ahh eee ahh

OHHH thought... why not just have the exhaust shop make a new sound pipe? Tthats prob even cheaper. lol
They do sound similar but the Renntech has a deeper sound to it. The design, manufacturing and style are soo close to Remus though... Honestly... Now I wish I knew. I'll just assume yes for now. lol
Oh and I've been in communications w/ Renntech to try and work out the rest of Stage1. The new cf airbox seems to be quite a chore.

[QUOTE=nrg_mike;4076065]You totally should! You mite as well buy the new sound pipe. It's prob similar in price and it'll allow you to swap sound levels depending on mood. LOL.

By all means, please don't misunderstand me. I don't mean to denigrate your purchase. I just never understood why someone would spend twice the money (or more, with Renn), for a "pre packaged" exhaust as compared to a quality shop bending a custom exhaust set-up.
Then, on top of it, allow them to plaster their name all over their products so they can get free advertising.
Again, not trying to upset you (or anyone else), but I personally never understood it. Maybe someone will make me see the light.
But... as long as you like it, that's all that matters, at the end of the day.

Well first off, I'd just like to start off by saying that I paid quite the fair amount for this. It was no where near what most would expect.
Next, I'd like to look at the idea of making a new exhaust setup with the aid of a muffler shop.
Quite a few people have the Magnaflow muffler so let's use that as a general/common item. The simple muffler alone usually goes for $100-150 (depending on what you want). Then you'd have to purchase tips (esp if you've already purchased the cheap $100 one). Next, you'd have to have the shop do your new piping. In most cases, crush-pipe from the catalytic converters only costs roughly 100-120 (also keep in mind that this will flow worse than the factory system). If you'd want mandrel bends this will cost more depending on a few choices. First choice would be how you'd like the bends. Do you want them to weld in each angle in sections, or do you want them to manually bend the pipe with a bending machine where a ball is pulled through the section to create the right bend without crushing the pipe? Mandrel bent piping usually runs 150+. Oh, and if you'd like to make this new system a bolt on or a clamp on, you'd prob have to add another $40 for the connections and any gaskets or hardware you may need.
So to add those, lets add $100 for the muffler, $40 for new tips, $120 for the bent piping, and $40 to weld the muffler to the pipe and another $40 for connection hardware. This totals about $340 for a custom exhaust that can be un-installed and put back to stock. (I could compare just adding a muffler but that's an unfair comparison to a new exhast setup IMO.)
Honestly, for $340, I would much rather have bought Howard's Remus exhaust system. It would be much easier and less time consuming.
Another reason I chose to go with a system that was pre-designed and created for the car was because I've had many custom exhausts done before. The process of it all while fun, is time consuming and may lead to problems down the line. These problems include, welds, gaskets, hardware, hanger locations and muffler/baffle fade.
Next reason is because I come from a manufacturing background and understand the differences between materials, welds, piping material, etc. Just to set the record straight, I've worked as a manufacturer for years and have manufactured exhausts for TRD, and DC Sports. I've also sponsored many exhaust companies with products ranging from wheels and body kits, to steering components so my relationships w/ the companies are quite fair. It is because of my background and knowledge that I appreciate a developed system that was made for your vehicle vs a system that was made to fit your vehicle.
Lastly, one simply cannot say that brands don't matter. Especially if you drive something like a Mercedes. We own them for a reason.
For me, I'm not going to lie. My waredobe consists of almost all Burberry, my watch collection includes brands like Bell&Ross, Rolex and B&M. Hell, my airsoft team callsign was "Prada" because of my preference for quality. Sadly, all things are not created equal. Coke is better than RC Cola. Dr Pepper will always be better than Walmart's Dr Thunder. Johnnie Walker Blue Label 200th anniversary will always top Boone's Farm. Like it or not, brands do carry more quality behind them. It's the same reason we can't stand the knock-off stuff and the ebay stuff.
So in the end, pardon me and the many like me that would prefer the dry-aged fillet mignon over the flank steak. I understand that the last part may make me sound like a total brand douche but if any of you have met me, then you know me and probably understand the reasons behind the rant.
Thank you for reading.

Different opinions and different taste.
Edit
Perfect example, buddy has wheels on his 204. I hate his wheels and don't think it looks good at all (never told him). He told me he doesn't like my wheels. He says why would you ever pay money for the wheels you have (engraved brand). Again just different taste and different look. Why would anyone buy real Brabus wheels when they can get reps for much cheaper...guess what there is a reason to it

This is how I look at it: The Renny exhaust was designed and made by humans. The exhaust Gods don't work for Renntech. It was made at the lowest cost possible in order to be able to make enough of a mark-up to make a profit. Though, in Renny's case, they like to REALLY mark stuff up because of the name.
Now, granted, I'm sure Renntech has "purchasing power" as they probably buy more than two mufflers and more than 40 feet of tubing at the same time. But at the end of the day, their exhaust is designed and made by a person, just like an independent shop would have done.
If you have a background in something, why pay someone a good mark-up to buy their stuff? I mean, seriously... It's a bunch of pipe, not rocket science. If you have all tis experience, you should be able to calculate flow, temperatures, bend angles and all the other stuff that's involved in making a custom exhaust. Hell, if you have all this experience manufacturing exhausts for TRD and DCS, this should be as second nature to you as breathing.

I've sponsored a bunny rabbit once. Does that count?
I'm a cowboy boots, generic jeans and shirt kinda guy. I own several suits, but I don't wear them. I'm not in this world to impress anyone. Though, I must admit, I prefer Tony Lama boots to Justin boots. I will not
lower my standards on the boot subject.
If you do have a reply, I may not get to it for a while, we're going to exact genocide on a Prairie Dog town for a farmer friend of ours. Ammo is loaded, Rifles are oiled, BBW grille is in the back of the truck, and the deer steaks are in the coolers.
I totally see your points. Honestly, we all could shoot this one back and forth forever and debate the manufacturing, marketing and production of brands vs labels and private labels.
I'd just like to generalize my response to say that buyers feel comforted by brand names they recognize and know. In general, there's a belief of more quality behind the products being purchased. I serve as a Brand Ambassador for GQ Magazine and know this all too well.
So in reply to the comment about figuring exhaust flow and all, I would like to say, that sure, I could have had an in-house tech design my exhaust (I am by no means an engineer) but I trust that Renntech's designer did a good job. This doesn't take away from Tony'S (from Valley Muffler, they've been doing my exhausts for 10 years) ability to make me an exhaust and brands like Magnaflow, but would most rather put a "Tony" on their car or a Renntech, Remus, Eisenmann or Brabus?
