Turbo Exhausts

[EMC]

Rob, what you're saying makes sense when those products are used in the specific application. For example, the fan delete can be argued that it is a good mod for an NA car, same goes for underdrive pullies and crank pullies. Turbo cars are different. Many of the mods we did on an NA will not only not be benificial, but might even keep the car from running up to its potential.

A catback exhaust from UUC is great on an NA car, but a waste of time and money on a turbo application. Same goes for the flywheel IMO. It might not hurt anything to have it there, but its not going be worth the extra money.

Being a supporting vendor is great, but you have an agenda. I am a guy who only has his experiences. A few posts up from here a good friend of mine gives you his impressions before and after the turbo install on his lightweight flywheel. I have driven his car NA with the lightweight flywheel, and I have driven it with the turbo on.

The car was fast before, but now it is faster than hell because of boost.

If you have a turbo car, the UUC TSE is about the best exhaust you can buy. Of course, this assumes that you need an exhaust to bolt up in place of something stock. I would not be suprised if guys with an AA cat back exhaust would benefit 20 or even 30 horsepower by switching to a UUC muffler section. With the money they could get from their AA exhaust, buying a UUC TSE would only cost them a couple hundred to net another 20+hp. That's a bargain. You can't come close to that hp/$ value with a naturally aspirated M3.

Sure, Rob may have motives for posting. He's got a business to run and employees to keep employed. That's obvious. BUT...I've never known to lie about anything.

I'm assuming that many guys running a turbo are going to be removing the cats, and going for something straight off the downpipe. The TSE is beautiful, and you would really need to love it to not go a 3'' back to the tips.

EMC,

I'm sure you know more about this then I do....but better then a 3" turbo back setup? :confused

for the money, a magnaflow custom setup is cheaper and more efficiant....unless you can get your hands on an E36 HKS setup and work a little magic to make it a true 3" system. :pimpflash

I'm selling my AA crack pipe and Rogue DMS after I fab up such as system since a single 3" will flow better then two 2.25" setups. the y-pipe alone is just another disturbance that you'll want to avoid when working with a turbo exhaust.

I'd still rather have a 3" turbo back exhaust. I've seen a lot of AA cars that appear to run the AA muffler. Those cars would benefit greatly from a TSE which is a straight thru exhaust. The DMS is another good turbo exhaust.

Lots of people keep their cats on the car. I'm not one of them. But for those that run the stock cats and want to keep them, this is a great way to go.

Dual 2.5's should outflow a single 3.0 even if you count the "boundary layer". Wow, I haven't used that word in a long long time.

Magnaflow 3" is the way to go if you want all out performance. If that's not enough, just put an electric cutout in there. I looked at going to 3.5 and even 4.0", but it just wasn't worth the extra noise. My car is a daily driver, so I don't want it that loud. I'll post pics of my exhaust tomorrow night if I get a chance.

...Oh...sorry about the OT. This was a clutch thread.

[Rob Levinson]

"Agenda" comments should barely be dignified with a response and are inappropriate and insulting. I was an enthusiast long before I started UUC, and had these identical discussions way back on MSN Autos way before "smileys" and hidden e-mail addresses. Please don't insult my years of experience by commenting that I am just trying to sell something - I am not that kind of manufacturer/vendor.



A quick note on exhaust systems... the TSE is officially discontinued, and replaced by the RSC36. Details here:

http://www.uucmotorwerks.com/RSC36

I bring it up in this thread only to pre-empt any confusion about those looking for the TSE as recommeded by EMC, and also that it may be of special interest to turbo car owners.

The RSC36 is the only exhaust system that acts completely like a "straight pipe" exhaust in terms of flow... the Corsa-built RSC tuning elements (they're no longer called mufflers) do not contain restrictive baffles, nor perforated tube interiors. The Reflective Sound Cancellation technology, whose only in-pipe appearance is the small sound wave ports, presents a completely smooth interior pipe throughout the rear section. Technical details and pics in the link above.

This may be the most productive bolt-on system for a turbocharged E36.

I can always split the thread if desired.

as for the dual 2.5s, that's just more work when compared to the ease of a 3" turbo back setup. wouldn't you agree?

[themadhatter]

now we're really going into exhaust systems.

I know AA sells a turbo back setup and TT has one in the works...who else has a true turbo back system ready to buy?

time for a thread split.

Two smaller pipes are more work to fabricate, but easier to attenuate the sound. Maybe not a concern to all, but definitely to some street-driven cars.

A single 3" runs the risk of being too loud, or droning within the car. Available mufflers that knock the sound down sufficiently may negate the purpose of a big pipe in the first place. A baffled muffler, such as some of the generic mufflers used, definitely falls into that category.

YMMV, but it's food for thought as the various factors can have significant effects.

I absolutely loved the sound of the TSE. I had people pull over when they heard me coming up the canyon. :devillook However, the resonance/drone of it at lower RPMs made me sell it. I couldn't take it in a convertible. But if that is no longer an issue I am very interested in getting one again. The sound at medium/high RPMs is very addictive. Do you have a sound file of the RSC?

The lightweight flywheel rarely rattles in my car. It goes away when you drive or push in the clutch. You know that before you buy it and you make a choice. Come one, you don’t put solid aluminum bushings into your suspension and expect it to be as quite as stock, right? This is not specific to a product or a vendor, but you make a choice when you pick performance parts.

I highly value the opinion of the supporting vendors and they deserve respect for the products that they make available to us. Of course they think that their product is the best, nothing wrong with that. Especially if they make technical articles available to proof their point. It’s your choice if you are buying it, in this case literally.

Hopping off my soapbox. Just my $0.02

FWIW, I just had a custom 3" exhaust fabbed/installed last week for $450. That was with a Magnaflow 3" to 3" resonator and a 3" to 2-2.5" tailpipe. I sold my Dinan muffler for $475 so it was a no brainer for me.

The exhaust is quiet and does not drone on the highway, I couldn't be happier with it!

[caldweb]

Hey those of you with the 3" magnaflows, could you post pics, please?

Not a 3" but it's much more flow than stock. What I did here was use a B&B Triflow from an E34 M5 3.6L (2.5") from my headers back. This is going to be a supercharged car, I know headers with 2.5" outlets would be ideal but that wasn't within budget and several NA guys tell me that stock manifolds flow best for torque anyway. There are two magnaflow hi-flow 2.0 or 2.25" 4.2L capacity catalytics. The B&B exhaust seemed to be very free flowing. I am hoping that it flows much better with the extra air going through the motor when compared to the restrictive 1.75" stock system. I would think 2.5" dual is more capacity than single 3" no? It is certainly loud though.

Not a good one, it's very difficult to accurately capture the sound.

But in all reality, as far as interior sound goes, the experience is very similar to the RSC-based system we have for the E46 330i. With similar displacement and chassis characteristics, your E36 experience will not be much different. Note that the loudest interior noise at cruising is the wind noise:
