wich one and why!!!!!
Neither - too whiny on a 328. Something like a Bell or a Quicksilver normally works & sounds better - bit more of a deeper "bark" to them. I.
There'a gentleman in our local "group" with (I believe) a Stebro on his 328 - his screenname is Blue328GTS (maybe minus the "e" - can't remember) - and it sounds killer...
I've heard a tubi on one and it sounded absolutely awesome, its personal taste really, try and get to a ferrari trackday or something where there will be a good selection to compare
I too want to put an aftermarket exhaust on my 328 & I'm confused on which one to use. I have listened to the side by side audio/video of the stock, Capristo & Tubi on the 360, I personally like the Tubi (deeper, throatier sound) But while it's great to hear these exhausts I know that it's an entirely different set up compared to the 328. (USA version). I believe it's even more difficult when one listens to an exhaust and it's on a Euro Lambo, or Ferrari Enzo. It's a little hard to find 328 exhaust sound clips/users so I can make an informed decision. Anyone with sound clips for the different exhausts on a USA 328 would, in my opinion really be helpful. I really like the Tubi, but is the value really there when there's others?
Exhaust sound is definitely subjective. I'm not much for the Tubi sound nor price, so I looked at other options and decided on the Larini. I have their sports exhaust on my '85 Euro 308 and will post sound clips as soon as I get around to it. I have heard a Capristo on an '84 Euro 308 and it sounded good. I'd say about equal sound and perhaps a nudge going to the Larini, again, this is personal preference.
I have a Tubi on mine, and have been in 328s with the stock exhaust as well. While I love the sound and the look, to my ear the Tubi isn't much louder or throatier than stock. It does look magnificent through the rear grille below the bumper, whereas the stock exhaust looks very pedestrian. The sound is plenty loud for me. If money isn't an object, I'd recommend it. Another thought, though maybe less important, is that Tubi has a bit of name recognition and tends to be one of the few aftermarket things you can put on your car that may increase its desirability (although you won't recoup your costs by any means). Capristo might not factor into resale as much.
I checked out the X-ost muffler, & I think I remember that Daniel of Ricambi had one on his car. I liked the sound from the clips he posted, but again it was a 348. But when I looked at the Daytona site, the 328 exhaust looks like it is for a Euro version. Please correct me if I'm wrong. I'm not opposed to "sound" from the exhaust, I just don't want "tinny" but more throaty, & burble (sp?) on decleration. Previously I had a Borla with Ansa tips on my 308 2V, no cats. That was a little loud so I won't go that far, but considering the two exhausts are so different ie: two pipes on the 308 vs one pipe on the 328, I'm wondering?. Hence the request for 328 (USA) exhaust clips.
Mike - I have 2 US 328 systems of the X-OST inbound to me. They do not have a "tiny" sound at all... quite throaty. I have a beta customer already lined up, and we'll have sound clips as soon as possible. PM me if you are interested in also being a beta customer. The only obligation? Sound clips and installation pics. -Daniel
I have a Stebro muffler and a Stebro cat/"test" pipe on my 3.2QV and it sounds wonderful. Definitely throatier/deeper than the tubi - has some not insignificant amount of resonance however. Couple nice things about the Stebro: a) there are removable exhaust tips (4) which open things up a lot for the track or wherever, and b) the Stebro does not come highly polished so there's little or no "bling, bling" factor when it's staring at you from behind the exhaus grill - I like this more subtle appearance. It's a lot cheaper than the Tubi as well. Very good quality construction. Delivery schedule from Stebro is a little uncertain however. Pay with a credit card in case something gets messed up. Good luck!
Custom exhaust using inexpensive round tube Cherry Bombs from, i think, JC Whitney. The previous owner had this made. It is VERY light and free flowing. Perhaps TOO free flowing and debating adding some back pressure to the system. http://www.ispexperts.com/glen050406.wmv Image Unavailable, Please Login
Steven is on the right track..... Find a good custom exhaust house in your area and have them build you a system, it will cost you about $400 and it will perform and sound better than any $2,000 tubi...... I have done it on several 308's, and 328's and they sound and LOOK great.
...unless they don't do mandrel bending, which no one around here does. I still think there's a lot to be said for a true tuned exhaust system......up to a point($).
I have a Borla system on my 328; fairly loud with a clacking sound at idle. Been thinking about putting the factory muffler back on (for concours) but everytime I accelerate under a tunnel I change my mind...
well, def differences in taste, I don't think the SS looks blingy AT ALL. Now, if you put 21" spinners on your F, then THAT'S blingy.
A good exhaust shop that does mandrel bending is hard to find! I know I've asked around at the Automezzi auto show here in Colorado. Maybe I'm just not asking the right people? But in viewing Steven's set up, I tend to agree with him on the back pressure, (to keep "some" torque) also this set up is Euro since the intermediate pipe on the 1-4 bank (I think that's right/ ok, the header nearest the "trunk") has been modified to go to the left side of the exhaust. The same thing would need to be done to the 328 (USA) since the 1-4 header goes to the right side of the car & into the the intermediate pipe/(extension pipe from manifold to converter). I'm not opposed to this modification, in fact I would perfer going to this set up since it's some what more of a true dual exhaust. Again it's finding a shop that can (ie mandrel bending) & WILL do this.
Since Im in the market of an exhaust system for my 84 GTS QV maybe I should just wait till Aug 18th for the Concorso Italiano in Monterey to see what some of the 308/328 got on their system this way I can realy hear it and compare in person, what do you guys think? Mike
Thanks, though the previous owner deserves the credit as he did it. Dyno'ed the car 2 years ago and again last week and she seems to be in need of some back pressure as there is indeed some loss happening. Dyno numbers are about the same from each, which is good considering the added track time between the two measurements. The exhaust seems to be a dual system with each bank of four having it's own fun. There is no crossover pipe that i can see joining the two. The entire setup is quite lightweight, but as you can also see it is suffering from this New England harsh salt/sand environment so i need to clean/repaint it soon. Will probably do that when she is 'down' as i want to refresh the cooling hoses and a few small upper fuel line bits. Also want to have some other bits attended to... but that is always the way when you track a car often. Already have 8 track days on her this year alone. Below is May 06, 2006 dyno with three pulls. Note that KTR's dyno is said to measure things a bit lower than some others and the measurements are said to be at the flywheel. She needs some back pressure for sure. Image Unavailable, Please Login
Reminds me of the Great Allied Tire commercials of years ago "Tires ain't pretty". $1000 + for a muffler on a 308/328 is insane.....you never see it behind that gastly diaper on the 308. Use a supertrap to tune your exhaust and you will get any amount of Backpressure you desire. http://www.pegasusautoracing.com/productdetails.asp?RecId=4304
If you think your Ferrari is not a work of art , then put on a canada tire muffler. to many people put on cheap aftermarket parts, an then when the car is for sale ,what top dollar for a car that hasn't been service properly or have wrong parts on the car. You guys are driving a Ferrari not a Z28 . The companys that develop these exhaust system spend time and money to develop the sound and horsepower from mufflers. That doen't come cheat. Some people should not be driving Ferrari's.
It's actually not that hard with a little study and experience, and they don't spend that much tuning for hp, as they know sound and appearance are the selling points for this market segment (although dare I add 'name recognition'). The old FChat addage still applies:when you buy an aftermarket muffler, buy based on sound, not any promise of hp. The hp difference between any good exhaust system, if by Tubi or a good local race shop, is going to be close. For hp alone, you may never better with a straight through non-interconnected dual system as Steve's for our 180 degree flat crank V-8s. That is the exhaust system that takes maximum advantage of the even bank exhaust pulses - no cross over pipe needed as in an american 90 degree V-8 best to all rt
Horsepower from mufflers??? yeah for $2500 + maybe a couple of horsepower from a "pretty and shiny Tubi". These things are all about sound and marketing.....nothing more nothing less. Run your headers into a supertrap and tune it for your needs....sound or performance, take the $2400 you saved and buy a Z28
